Additional controls include a transmit key for front panel microphone PTT, volume knob for speaker and earpiece, automatic power up of the radio, remote radio reset, and DTMF from keypad. The remotes incorporate additional features including: Intercom mode 8 025-9448D

Typical Configuration Receive audio mute Secure mode for privacy Privileged supervisor functions In addition, the remotes have many LEDs and LCD icons that provide functional information to the user. Model 390 Options The headset interface box (Part No. 950-9674) provides an interface to replace the handset with a headset for hands-free communication. The programming kit (Part No. 950-0115) allows interface features to be changed from a personal computer. The kit consists of an interface cable, adapter, and programming software. There are connections for a desk microphone (Part No. 905-0329 or 905-0330), external speakers, recorder, headset (Part No. 950-0030 or 950-0032) and footswitch PTT (Part No. 950-9102). Three different wall transformers are available to power the remotes: 220 V, 50 Hz (Part No. 815-9028), and 115 V, 60 Hz (Part No. 815-9033) and switching power supply (950-0406). Typical Configuration Figure 2 shows a typical Model 390 Radio Remote system installation. Up to 15 Model 390 Remotes can be connected in parallel to control a single radio. Each remote can be located up to 600 meters from the radio and are connected to the Model 390 Radio Interface with three pairs of in-building twisted wire. The Radio Interface is co-located with the radio and is connected to the radio with an 8-connector telephone cable. 9

Introduction Figure 2: Typical System Configuration Installation is simple because the audio levels come pre-set from the factory, and the default configuration settings are ideal for most applications. Furthermore, maintenance and repair are minimized because of the advanced microprocessor circuitry used in the design of these products. Using the Documentation Who Should Read This Manual?

Specifications Operation This section describes the operation of the Model 390 Radio Remote. The functions that mimic the radio are described first, followed by a description of additional functions provided on the remote. Next, the display and LED indicators are explained. The section ends with a description of the available audio options for the remote. This section does not attempt to explain how to operate the radio. For a full description of the radio itself, its features, and operation, please refer to the radio s user guide. For information on using the remote, see the Model 390 Radio Remote user guide. Figure 3: Controls of the Desktop Remote 15

Operation Radio Functions This section describes the front panel controls of the Model 390 desktop unit in detail. Control LCD Volume Scroll Keys Cancel Key Description The liquid crystal display (LCD) of the Model 390 mimics the LCD of the MTM700/800 Motorcycle Control Head, and shows the current radio status. Typical information displayed includes current call information, aliases, and a data or status message. The LCD also shows a set of status icons on the top row (see LCD Icons on page 21). The volume level of the front panel speaker and the handset earpiece are adjusted at the same time by turning the Volume knob. These keys allow a user to scroll through messages in the stack, a list of preprogrammed groups, options, or radio IDs. These are the same as those programmed into the radio (for more information, see the radio s user guide). This key is used to cancel a call, erase an entry, or delete a message. This key functions in the same way as the key on the control head. Select Key To select options when the appears in the display, press this key. It can also be used to select other options, such as the desired talkgroup or range. Phone Call Key Direct Mode (DMO) Key Message Mail Key This key places the radio into phone mode, which allows connection to the phone system on equipped systems. With the handset off hook and the PTT bar pressed in, a full duplex call is possible. This key allows local radio-to-radio communications without using the repeater. This function is typically used if a site is down or unreachable for some reason. When in direct mode, the LED next to the key will be on. The same radio functions allowed in direct mode are available through the remote. To enter the direct mode, hold this key down for a period of time until the mode initiates (the length of time may vary from radio to radio depending on its programming). This key places the radio into message mail receive mode. Status Mode Key This key allows a status message to be sent to the dispatcher. Use the keypad or scroll keys to select the appropriate message, and press PTT to send. Range Key Group Call Key This key is used to select the desired range of a group call. When pressed, an arrow will appear next to the group field. The Scroll keys can be used to select the desired group. This key puts the radio into group mode. The current group will be displayed. 16 025-9448D

Radio Functions Control Emergency Key Private Call Key Transmit (PTT) Key External Alarm Key Menu Key Alphanumeric Keypad Hook Switch Progress Tones Description This key allows the remote to send an emergency call (see the radio s user guide for more information). The Model 390 Interface may be configured to trigger an external remote output on receipt of an emergency call. This key allows the radio to be placed into private mode. Use the alphanumeric keypad to select a recipient or use the Scroll keys to select from a list. (The Model 390 Interface may be configured to trigger an external remote output on receipt of a private call.) To key the radio, first select the recipient or group, using the appropriate keys, then press the Transmit key on the remote. There will be a delay while the radio negotiates and acquires a channel. This delay is dependent on the radio and traffic on the system. If the recipient is unavailable or the system is busy, a tone is heard and the LCD displays any message from the radio. Once the channel has been acquired, the TX LED turns on to indicate that the unit is transmitting. Now begin speaking into the Model 390 Remote. Its internal microphone is located near the front, right edge of the unit, and picks up a person s voice at an arm s distance, though audio quality improves as the distance is decreased. Release the Transmit key to hear receive audio from the front panel speaker. To use the handset to key the radio, remove it from the cradle. Press the PTT bar and wait for the TX LED to come on steady. Speak into the handset mouthpiece. Release the PTT bar to hear receive audio from the handset earpiece. To clear down a call, press the Cancel, Group, or another mode key. This key allows a user to change the status of the external alarm output on the radio. This is usually used to trigger some external event when a call comes in. This key functions in the same way as the External Alarm key on the control head. This function is different from the private and emergency call triggers that can be set on the remote. To change or verify menu features of the radio, hold down the Mute key and press and release the Private Call key. The current radio settings will be displayed. Press the combination again to select the next setup menu. Use the Select key to change a setting. These keys function as a 12-key keypad for alphanumeric entry, dialling, or selecting a talkgroup. This keypad works just like the control head keypad. The hook switch on the remote has the same function as that of the hook/clear button on the rear of the radio s mic. This allows a user to cancel or clear down a call by placing the handset on hook. All progress tones generated by the radio will be heard either from the front panel speaker or from the handset earpiece, depending upon whether or not the handset is off hook. For more information about progress tones, refer to the radio s user guide. 17

Operation Additional Model 390 Remote Functions Function Intercom Key Mute Key Description Intercom mode allows users at various Model 390 Remotes to talk to one another without keying the radio and tying up a channel. To enter intercom mode: 1. Press the Intercom key. The Intercom LEDs on all the Model 390 Remotes will flash. 2. To talk to someone at another Model 390 Remote, press and hold the Transmit key while speaking into the front panel microphone, or remove the handset from the cradle and press and hold the PTT bar while speaking into the handset. While any Model 390 Remote is sending audio, the Intercom LEDs on all the Model 390 Remotes turn on steady. 3. To listen for a response, release the Transmit key or the PTT bar. 4. To exit intercom mode, press the Intercom key on any Model 390 Remote. The Intercom LEDs will all turn off. As long as the Intercom LED is flashing, the system is in intercom mode, and pressing the Transmit key or the PTT bar does not key the radio, but only transmits to the other Model 390 Remotes on the system. While listening in the intercom mode, receive audio from the radio can still be heard. If no key is pressed on any Model 390 Remote for 30 seconds, intercom mode times out, and the system returns to normal operation. Intercom mode may be disabled through system programming. For information on disabling intercom mode for a single Model 390 Remote, see Remote Configuration on page 29. To mute the receive audio of any Model 390 Remote, press the Mute key. The Mute LED will turn on and a positive indication beep will be heard from the remote to indicate that the receive audio is muted. Note that mute mode does not time out and that it does not affect any other Model 390 Remotes. To unmute the audio, press the Mute key again, and the Mute LED turns off. 18 025-9448D

Additional Model 390 Remote Functions Function Secure Mode Key Description Secure mode allows a user at one Model 390 Remote to talk to someone over the air without anyone at parallel Model 390 Remotes hearing either side of the conversion or being able to control the radio. It effectively locks these users out, leaving one person in full control of the radio. NOTE: Even in secure mode, communications over the channel occur normally, giving no additional security beyond that which the radio provides. Supervisor To enter secure mode, press the Secure Mode key. The Secure Mode LED comes on. The Secure Mode LEDs on all the other Model 390 Remotes blink to indicate that they cannot control the radio. The Mute LEDs also illuminate on all the Model 390 Remotes except the one that initiated secure mode to indicate that their receive audio is being muted. The radio may be controlled as usual by the person who initiated secure mode, and current radio status continues to be displayed on all Model 390 Remotes. As long as the Secure Mode LED is on, users at all other Model 390 remotes will be unable to receive audio or key the radio. To exit secure mode, the initiator must press the Secure Mode key again. If no keys are pressed on the initiating Model 390 Remote within 60 seconds, however, secure mode times out, and the system returns to normal operation. Additionally, returning to normal operation when the secure mode initiator hangs up the handset can be set in system programming. Secure mode may be disabled for all remotes in system programming. See System Parameters on page 42. For information on disabling the secure mode for an individual Model 390 Remote, see Remote Configuration on page 29. Any number of Model 390 Remotes in a system may be configured as Supervisors. These remotes are immune from the effects of secure mode. In other words, when another Model 390 Remote initiates secure mode, all Supervisor remotes are still able to hear both sides of the conversation and control the radio. Furthermore, when a Supervisor remote initiates secure mode, the mode does not time out. For more information on configuring Model 390 Remotes, see Remote Configuration on page 29. 19

Operation Function Supervisor Takeover Incoming Call Trigger Adjacent Deskset Muting Radio Reset Description There are two types of supervisor takeover: 1) A Supervisor remote may be configured so that it can kill an undesirable call without waiting for keys to be released, and 2) Any remote (Supervisor or not) may be configured so that it can physically disconnect downstream remotes from the system for a more positive form of control. Pressing the Secure Mode key initiates supervisor takeover. The first type of supervisor takeover occurs when a Supervisor remote enters secure mode. The second type of supervisor takeover requires that supervisor takeover be selected in system programming. The FET output of the remote is then used to control an external relay, which is used to disconnect the downstream remotes. The output is a pull-to-ground and remains active for as long as secure mode remains in effect. For more information on using this output, see Section 4, Installation. The FET output can alternatively function as an incoming call trigger. (see the following entry: Incoming Call Trigger) If the disconnect-type supervisor takeover function is not used, a setting in system programming allows the FET output on remotes to be used to trigger an alarm or other notification of an incoming private and/or emergency call. For more information on using this output, see Remote Configuration on page 29. When two or more Model 390 Remotes are located in the same room or within earshot of one another, audio feedback may be a problem. When one user keys the radio, the audio will be heard at the other Model 390 Remote and may cause feedback to the first. To prevent this, each Model 390 Remote may be individually configured to mute its receive audio while another Model 390 Remote is transmitting. For more information on enabling this option, see Remote Configuration on page 29. Sometimes it is desirable to reset the radio remotely, usually as a last resort. By pressing the Mute and Cancel keys on a radio-reset-enabled remote, the radio interface will attempt to cycle power on the radio. All users will receive a notification before this takes place. It should be emphasized that this feature is designed to be a last resort method of gaining control of the radio. The user should probably attempt to force the radio to re-register by changing modes first. If the user has to perform this task often, it may be a symptom of some other problem with the radio or radio settings. For more information on configuring the Model 390 Remote, see Remote Configuration on page 29. 20 025-9448D

LCD Icons LCD Icons The top row of the LCD displays icons to convey status information from the system and the radio. Icon Description Private Call This icon indicates that the radio has received a private call request. When the call is accepted or rejected, the icon goes away. Alarm This icon indicates that the radio s external alarm output is armed. (This is not the same as the remote s output that can be triggered by a private or emergency call.) Antenna This icon indicates service and single cell mode. When flashing, this icon indicates that the radio could not get coverage. Signal Strength The three bars indicate the received signal strength (RSSI). Three full blocks indicate maximum strength, whereas three empty blocks indicate a weak signal. If the antenna icon flashes as well, then the radio may not be able to get signal coverage. In-Use Indicator In the upper right corner of the LCD is the animated In-Use indicator. When this icon is displayed, another Model 390 Remote is currently using and controlling the radio. No key can be pressed (apart from the Mute or Secure Mode keys on a Supervisor remote) until the controlling remote has finished using the radio. Loss-of-communications If the continuity check function is enabled and this icon appears in the LCD display of the remote unit, it indicates that the remote has not heard from the redio interface unit for 6 minutes or more. 21

Audio Accessories Audio Accessories Accessory Description Desk Microphone An external dynamic desk microphone may be connected to a Model 390 Remote to key the radio while the handset is on hook. If connected properly, it will operate just like the front panel microphone. External Amplified Speaker Headset Footswitch Recorder An external amplified speaker may be connected to a Model 390 Remote in addition to, or in place of, its front panel speaker. The Volume knob simultaneously adjusts both the volume of the external speaker and the volume of the front panel speaker if connected. An optional headset interface box may be used to plug a headset into a Model 390 Remote in place of the handset. Alternatively, a headset with flying leads may be connected directly to screw terminals in the Model 390 Remote. In either configuration, the headset replaces the handset. There are three possible setups for switching between the headset and the front panel speaker and mic (or desk mic): 1. Permanently enable the headset, thereby permanently disabling the front panel microphone and speaker as well as any desk microphone and external amplified speaker. This involves shorting two screw terminals together. The radio is taken on and off hook by lifting the handset from and replacing it to its cradle. 2. Leave the handset in its cradle while using the front panel microphone and speaker, then lift the handset off hook while using the headset. Use an external closure to ground, such as a footswitch, to activate the headset. Press the switch to use the headset. Release the switch to use the front panel microphone and speaker. Again, the radio s hook switch is controlled by the handset s hook switch, regardless of the state of the headset. 3. Use the jack sense signal on the optional headset interface box to activate and deactivate the headset. Plug the headset into the box to use it, and unplug the headset to use the front panel microphone and speaker. Just as with the first possible setup, the radio hook switch is controlled by the handset s hook switch, regardless of the state of the headset. A footswitch may be used to control PTT for the front panel microphone or an external desk microphone. Footswitches may also be used for headset PTT and headset takeover. Headset takeover controls whether the headset or the front panel mic and speaker are active. An external recording device may be used to record all TX and RX audio from and to a Model 390 Remote. TX audio and RX audio are summed together and presented to the Recorder Audio output. The recorder will be activated whenever RX audio is present and also whenever that Model 390 Remote is transmitting (over the air or in intercom mode). 23

Operation 24 025-9448D

Overview Installation! Caution! This equipment generates, uses, and can radiate radio frequency energy. If not installed and used in accordance with the instruction manual and commonly used radio practices, it may cause interference to radio communications. Installation of the Model 390 Radio Remote system should be accomplished by personnel who have experience with remotes and radio systems. Overview Figure 4 shows a typical system installation, with the Model 390 Radio Interface colocated with the radio. As shown in the figure, a modular telephone cable connects the interface to a telephone wall jack. In-building telephone wiring connects that wall jack to a punchdown block in a central location. In-building telephone wiring also runs from this punchdown block to wall jacks near the desired locations of the Model 390 Remotes. Finally, modular telephone cables connect the Model 390 Remotes to these wall jacks, completing the circuit. The remotes can either sit on a desk or be mounted on a wall.! Caution! The radio and the radio interface should be co-located whenever possible. The interface should NOT be separately grounded. It is important that the radio interface ground is through the radio interface cable and the radio. 25

Installation Figure 4: Typical System Installation Required Equipment The only equipment required is some assorted hand tools. However, to install in-building telephone wiring to the punchdown block and jacks, additional tools may be needed. Installation Phases Installing the Model 390 Radio Remote system can be broken down into three phases: 1. Configuring system components 2. Installing and connecting system components 3. Initializing the system Before starting to install the system, be sure to read through this entire section to become familiar with the components, the system functions, and how different settings interact with each other. Before starting, you should know which system functions you want to enable for which remotes. For example, which remotes in the system are to be Supervisor remotes? Phase 1 Configuring System Components The first phase involves configuring the radio, the interface, and then the remote. 26 025-9448D

Phase 1 Configuring System Components Radio Requirements! Caution! Do not plug the fist-microphone into the MTM800E radio control heads as this is known to cause audio distortion issues. The use of a fist microphone causes the audio levels to drop dramatically requiring a M390 reset. Model 390 for MTM700/800 (901-9617) The radio must be equipped with the Expansion Head, which provides a DB25 connector on the front panel for connection to the Model 390. Do not attempt to use an MTM700/800 radio with the Standard Control Head with the Model 390. The keys and indicators of the Model 390 Radio Remote emulate the MTM700/800 Motorcycle Control Head. If using an MTM700/800 equipped with the Motorcycle Control Head, disconnect the Motorcycle Control Head and attach the Model 390 in its place. Radio Configuration To ensure correct operation of the radio and remotes, it is recommended that the radio be set up for use as though it had a full feature front panel attached, using the RSS (Radio Service Software) and adapter (or equivalents) from Motorola.! Caution! The radio should be programmed without the radio interface connected. Interface Configuration Configuring the interface consists of setting jumpers on the interface s PCB (printed circuit board) if necessary. Most of the jumpers can be left in their default settings (position A). The jumpers and their functions are described in Table 1. Figure 5 shows the approximate location of the jumpers. 27

Phase 1 Configuring System Components Remote Configuration Configuring the remote consists of setting jumpers on the remote s PCBs if necessary. The jumpers and their functions are described in Table 2 and Table 3. Figure 6 shows the approximate location of the jumpers on the remote s main PCB. Figure 6: Location of Jumpers on the Remotes Main PCB To access the keypad PCB, see the top-level assembly drawing in Section 6, Troubleshooting and Repair. 29

Installation Table 2: Configuration Jumpers on the Remote Main PCB (702-9892) Jumper Purpose Positions JP1 Reserved for Internal Use Do Not Cut JP2 Reserved for Internal Use Do Not Cut JP3 JP4 JP5 JP6 JP7 JP8 JP9 JP10 Supervisor: This jumper determines whether or not the remote is a Supervisor remote. Supervisor remotes are immune to the effects of secure mode when initiated by others. Furthermore, when a Supervisor remote initiates secure mode, it will not time out. Adjacent Deskset Muting: If this feature is enabled, the RX audio of this remote will be muted whenever another remote is transmitting. This is useful if two or more remotes are located in the same room. In such a case, feedback may occur when one of them transmits. To eliminate this problem, Adjacent Deskset Muting should be enabled on the remotes located together. Radio Reset: If the interface has been programmed (see Section 5, Programming ) to restrict radio resetting, use this jumper to allow this remote to reset the radio. Handset / Headset Earpiece: This jumper sets earpiece audio gain to the proper level for either the handset or a headset. Handset / Headset Mouthpiece: This jumper sets mouthpiece audio gain to the proper level for either the handset or a headset. External PTT: This jumper determines how audio will be routed when the external PTT input is activated. Audio is either taken from the external desk mic input or from the front panel microphone. Front Panel Speaker: This jumper is used to disable the front panel speaker if an external speaker is used. The front panel speaker connector plugs directly onto this jumper in either position A or B. Audio Test Points: TP1, TP2, and TP3 provide a convenient place to monitor volume levels during initial system setup.

Not Cut - Enabled Cut - Disabled Not Cut - Enabled Cut - Disabled Not Cut - Enabled Cut - Disabled JP6 Unused Do Not Cut Phase 2 Connecting System Components Once all the components of the system have been configured, they must be installed and connected properly. There are four aspects to this step: in-building wiring, radio connections, interface connections, and remote connections. Do not apply power until all the system components have been configured and connected (see Power-up on page 36). In-building Wiring The connection between the remotes and the radio interface requires three twisted pairs of wires, 24 gauge or larger. Typically this would be in-building telephone wiring terminating at modular wall jacks at the locations of the radio interface and each remote. The modular cables supplied with the radio interface and remotes require 6-conductor RJ11 jacks where pins 1 and 6 make a pair, 2 and 5 make a pair, and 3 and 4 make a pair. The remotes may be connected in any configuration (star, T, or multi-drop) as long as no remote is located more than 600 meters (electrically) from the radio interface. 31

Installation Radio Connections Install the radio per the Motorola installation manual. To minimize noise pickup and crosstalk, avoid placing the antenna and its cable close to the power cables of the radio or close to the modular cables from the interface to the remotes. Note If a control head is attached to the radio, remove it to ensure correct operation. Do not apply power until all the system components have been configured and connected (see Power-up on page 36). Interface Connections The radio interface should be co-located with the radio whenever possible. It is connected to the radio with the 8-pin RJ-45 radio interface cable, Part No. 709-7585 for the MTM700/800. It is connected to the remotes with a 12-foot, modular cable (Part No. 709-7416). Interface to MTM700/800 Connections To connect the interface to the MTM700/800, complete the following steps using Zetron Radio Interface Cable 709-7585: Connecting to the MTM700/800: 1. Connect the DB25 connector of the interface cable to the DB25 connector on the front panel of the MTM700. Secure the connector by tightening the jack screws. 2. Connect the modular end (RJ45) of the radio interface cable to the 8-pin telco socket on the rear of the interface (marked To Radio ). Note When connecting to an MTM700/800 radio, use Zetron cable 709-7585. Do not use a cable with the pinout shown in Figure 4-4. Interface-to-Remote Connections Connect the 6-conductor telco modular cable to the 6-pin telco socket (RJ11) on the rear of the interface and to the wall jack. 32 025-9448D

Phase 2 Connecting System Components System Programming Now is an ideal time to program the radio interface if desired. Refer to Section 5, Programming, for more details.! Caution! It is important to disconnect the programming cable from the interface front panel once the correct system parameters have been programmed into the interface. Remote Connections Power Figure 7 shows the connectors on the remote s main PCB for power, the in-building telephone wiring, and audio accessories and the FET output, which is used for supervisor takeover or incoming call triggering. Power must be supplied to the Model 390 Remote through TB1 on its main PCB. If a 12 VAC wall transformer is used, connect it to pins 1 and 2 of TB1. If a 12 VDC supply is used, connect the positive side to pin 1 and the ground side to pin 3 of TB1. Do not apply power until all the system components have been configured and connected (see Powerup on page 36). Figure 7: Connectors on the Remote Main PCB Remote-to-Interface Connections Use the supplied 6-conductor modular cable to connect J6 on the remote s main PCB to the in-building wiring that runs to the radio interface. 33

Installation Audio Accessories Use TB3 on the remote s main PCB to connect optional audio equipment, such as a desk mic, headset, footswitch, external amplified speaker, and recorder. A pin out of TB3 is given in Table 4. Details on connecting the TB3 pins are given in Table 5. FET Output TB3 pin 12 is used for a supervisor takeover or incoming call trigger relay. Details on connecting the TB3 pin 12 are given in Table 4: Pinout of TB3 on the Remote Main PCB Pin # Function In / Out 1 External PTT Input 2 Desk mic audio Input 3 Ground 4 Headset mic Input 5 Headset PTT Input 6 Headset takeover Input 7 Headset speaker Output 8 Ground 9 External speaker Output 10 Recorder audio Output 11 Recorder enable Output 12 Supervisor takeover/incoming call trigger Output Wall Mounting a Remote Remotes may sit on a desk or be mounted on a wall. Mounting a remote to a wall: (contact Zetron for parts) Note The Model 390, as shipped, does not include a wall mount handset clip. Before starting this procedure, call Zetron Customer Care group at (425) 820-6363 and request the following part numbers: 415-0705 (clip), 220-0007 (screw). 34 025-9448D
