2 The brief was just a few simple words on a single sheet of paper - yet the task was enormous: "Create the best sound in the world regardless". Two years after delivering the brief to our sound technicians, our club sound-system was ready. Housed in a specially constructed room simply referred to as 'The Box', it was the result of intensive research across the globe, utilising specialists in all areas of sound and electronics. Bass experts from the USA, highfrequency boffins from Scandinavia and cabinet builders previously agonising over Rolls Royce dashboards, all finally came together with a host of other technicians, boffins and anoraks to build what has now become a legend to dance music fans across the globe. Since then our sound-system's become an obsession - religiously stripped down each week, the highly tuned system, likened to an F1 racing car, gets constantly upgraded to retain its state-of-theart status. More recently the addition of digital processing means sound can be thrown around the Box from all angles and tuned to replicate a garage (well that's where it all started!) or a stadium. But, above all, we've developed 'M-Bass' - unique digitally processed algorithms delivering the absolute best, most awesome low frequencies ever. 2

3 After 10 years of refinement, tweaking and pampering, and with the advent of advanced chip technology, we can bring you your very own 'M-Bass' - the true sound of The Box right in to your very own home, or the palm of your hand. So times may have changed, as has technology, but whether it's for our club or audio products, the brief's as true today as it ever was - "Create the best sound in the world regardless". 3

6 What is digital radio? DAB (Digital Audio Broadcasting) is the next generation of radio. DAB was developed in Europe by a consortium of broadcasters and manufacturers. DAB uses digital compression techniques to transform the source material, i.e. music and speech, into digital computer code before it is transmitted. The computer code consists of electronic ones and zeros called binary digits or bits. The binary code is then multiplexed or grouped together to create a superior signal, when compared with the older analogue system, with the following key benefits: caused because radio waves do not behave in an orderly fashion, but bounce and reflect off buildings and mountains etc. DAB sees this as an advantage and uses the direct and reflected signals to actually reinforce the end result. No need to re-tune. A single DAB frequency can be used to cover the whole of the UK, so solving many of the problems experienced with the earlier analogue system. Near CD quality sound. Because DAB is binary coded, the receiving equipment is only expecting to receive a series of ones and zeros, so any other interference is ignored, resulting in very high quality audio. Interference free reception. Analogue systems suffer from an effect called multipath distortion. This is 6

7 Getting Started Carefully remove your Ministry of Sound MOSDR011 Digital Radio from the box. You may wish to store the packaging for future use. Read these instructions before operating the radio. In the box Inside the box you should find the following items: The Digital Radio A set of DAB headphones Two size AA batteries The User Guide If any items are missing call the Helpline on Battery installation Remove the battery compartment cover clipped to the rear of the radio by sliding the cover away from the nameplate using your finger on the indentations below the nameplate. The cover will become free when it is slid back a few millimetres. Place the two supplied batteries in the compartment paying attention to the polarity of the batteries. Orientate the batteries as shown in the diagram above noting that the two batteries face in opposite directions in the compartment. The negative end of each battery should make contact with the large spring terminal in the compartment. If the batteries are inserted incorrectly, the radio will not switch on. The design of the terminals is such that incorrect orientation of the batteries will result in them not being connected to the radio, thereby protecting the radio from damage. 7

8 The screen The radio employs an STN transflective blue backlit LCD screen. It has a row of fixed icons across the top of the screen that indicate user settings and provide information to the user about the status of the radio. Below the icons there is a two-line alphanumeric display with sixteen characters on each line that displays information about the received stations. The backlight allows the screen contents to be easily viewed in dark ambient conditions. The screen is backlit as follows: When the radio is switched on. Backlighting remains on for 5 seconds. When the power key is pressed to turn off the radio. At any key press. Backlighting remains on for 3 seconds. When a suitable external power supply (4.5V d.c.) is plugged into the power supply socket on the radio, the backlight is turned on and remains on while the radio is powered externally. Fixed Icons Volume level indicator You can set the volume level to any of fourteen preset levels. The icon displays the set level by displaying an increasing number of bars (from 0-7) as the volume level is increased. The volume level icon seen top left corner of the LCD display illustrated on this page shows the radio set to full volume. The speaker symbol in the icon remains on at all times. Battery level indicator The state of the batteries is indicated by the battery icon. The number of bars (0 to 3) indicate the power left in the battery. An unused (new) battery should indicate three bars as shown in the LCD screen shown on this page. If only one bar is displayed, this means that the power available is low. No bars indicate that the batteries are very low. When the power is too low for the radio to operate, the icon will flash and the unit will shut down automatically. 8

9 Time The time is displayed in a 24-hour digital format. The clock is only displayed when DAB is being received. It shows the time broadcast by the DAB stations. Favourites/Heart The heart-shaped favourites icon is only displayed when you have set the received stations to list in the order of the most played stations (your favourites). Graphic Equaliser The eq icon indicates the type of equalisation you have chosen to apply to the station playing. There are six different settings to choose from. Note that the equalisation setting can only be altered when a station has been selected. Signal strength The signal strength icon provides an indication of the signal strength of the station currently playing. It is dynamic and it changes as the signal strength changes. The icon displays as one of four states that indicate no minimum signal received through to strong signal strength received. Switching the radio on Check that the batteries have been installed correctly. Ensure that the lock switch on the top panel is set to the unlock position. Plug in the headphones into the jack on the side of the radio as shown. WARNING DO NOT TURN ON THE RADIO WITH THE HEADPHONES CONNECTED AND THE EARPIECES INSERTED IN YOUR EAR. LOUD SOUNDS CAN DAMAGE YOUR HEARING. The headphones also act as the aerial, so it is important that they are plugged in prior to switching on the radio or you will not be able to find any stations. Please note that this radio has only been designed to operate with the supplied headphones. 9

10 Press the power switch on the top panel. The screen will light up and the line of icon indicators will be seen, along with a welcome message. After a short delay, the message is replaced with other text as described in the section entitled Using the Radio. See page 16 for further details. Battery level indicator The battery level indicator icon should appear as illustrated on page 8. Headphones Place the earpieces in your ears, checking as you do so that the volume is not too loud. Associated components which aid reception are contained within the headphone cable. In some instances this cable will need to be repositioned to improve the reception quality. Switching the radio off Press the power push-button switch on the top panel and hold for about two seconds. The screen will be backlit (blue) during this period. Release the switch as the on screen information is cleared. The radio is now off. Locking the radio The radio may be locked while the radio is on or off. It is a good idea to lock the radio while it is off so as to prevent it from being turned on accidentally and resulting in the batteries being run down. The radio may be locked at times when you are listening to a station so as not to allow the settings to be accidentally changed, when carried in a pocket for example. Move the lock switch on the top of the radio to the lock position indicated by the arrow shown on the switch legend. To unlock the radio at any time, slide this switch to the unlock position. 10

11 Control buttons When switched on, all functions of the radio are controlled by the five push buttons on the front panel. The operation of these buttons to tune in and play the received digital audio stations are described in Using the Radio starting on page 16 of this guide. Power adaptor If desired, this radio may be powered from the mains by means of a suitable mains power adaptor. This item is not supplied, see Technical Specifications for details. When the DC jack is inserted, the radio is momentarily turned off. From left to right these buttons are referred to by their function as follows. info button preset button The Central Navigator button (multifunction) eq button menu button Rechargeable batteries The radio may also be powered by Metal Hydride rechargeable batteries.

16 Using the Radio Introduction The MOSDR011 is a portable digital radio. It can be worn or carried in a pocket or bag to receive and listen to digital radio. It runs from 2 x AA batteries providing enough battery life for approximately 8 hours continuous playtime. The screen allows users to view the DAB stations available, along with scrolling text known as DLS and other settings/service information associated with each station. The radio uses a set of headphones that act as the aerial and are specially designed to receive DAB signals. Control buttons There are seven buttons on the radio. Their functions are as described in the following overview. Power on/off The power button is used to turn the radio on and off. To turn on the radio, press and hold the power button until the welcome message starts to appear on the screen. A blue light (backlight) illuminates the screen - this stays on for about five seconds (or three seconds after the last button press, if button presses have been made). To turn off the radio, press and hold the power button for about two seconds. Lock The lock is a dedicated slide switch. It has two settings, lock and unlock. When in the unlock position all buttons are active when pressed. When in the lock position, all buttons are disabled. The lock switch can be set to lock while the radio is in use. In this situation, each time a button is pressed, a message appears briefly on the bottom line of the screen reminding you that the Key lock is ON. The radio cannot be turned off using the power button until the lock switch has been set to the unlock position. 16

17 Central Navigator While the radio is playing, the Central Navigator button has three functions: As a volume control. Push the button forward (UP) to increase the volume and backward (DOWN) to reduce the volume. Its action can be heard immediately in the headphones and is indicated on the screen by the appearance of the volume icon. As a scroll button. Push the button to left and right to scroll through the menus displayed on the bottom line. Push left or right to scroll left and right. To select a menu option. Press the button vertically down when you want to select the menu option in view on the bottom line of text. Info Press info to step through the available information transmitted along with the audio signal for the station you are tuned to and named on the upper line of text. The display information is displayed on the bottom line of text and includes the station content, name, program information and some technical broadcasting details. 17

18 Menu The menu button is used to access the first item in a list of options that are presented on the bottom line of text when the menu key is pressed. Other items are accessed using the scroll button (described earlier). There are four primary options: Station order, Manual tune, Autoscan local and Version number of the embedded software. The menu button has a second function. When held for several seconds, the radio resets to the factory set values. All settings you have modified or entered will be cleared. This reset will also clear the station list which your radio will have compiled automatically. Preset The preset function allows you to store up to ten radio stations that can be quickly selected for playing. Previous presets can be overwritten when not required. EQ Each press of the eq button steps through the six available equalisation presets and applies the setting to the audio signal being played. The available presets are: Flat, MBass, Monitor, Studio, Club and Arena. You can identify the particular one applied from the eq icon on the top line of the screen and the table shown opposite. Operation The MOSDR011 Digital radio uses an LCD screen and a unique key arrangement to navigate its functions. The screen has a set of custom icons (see opposite) and a two-line, alphanumeric display which can display up to sixteen characters on each line. Back light The screen is illuminated blue when a button is pressed as follows: For 5 seconds each time the radio is turned on when internally powered by its batteries. For a short period prior to shut down when the power button is pressed to turn off the radio. For up to 3 seconds after a button has been pressed. Continual pressing of keys to make the back light come on will drain the batteries. 18

20 The radio may be powered by means of a suitable external d.c. supply. In these circumstances, when the adaptor connector is inserted, the radio circuitry detects this and turns on the backlight. The backlight remains on for the time the external supply is used. This power supply could be a conventional mains power adaptor with the properties detailed on the Technical specifications page. You cannot change these timed settings. Additional information Wrapping In most cases when navigating a menu, the list will wrap to the start of the menu - it will appear to be an endless loop. New In most cases, if a menu calling button is pressed while in another menu list, the new menu is displayed. Timeout If during the navigation of any menu there is no button-press for a period of seven seconds, the radio returns to the play screen. In general, when a timeout completes, the display will return to the toplevel interface. Power down On power down, the current settings and station lists are saved, so that when the radio is next switched on, these settings are retained. This will not happen if a factory reset has been made prior to power off. The settings will then be the default factory settings. Non-volatile memory The parameters (e.g. volume, presets, display mode) are saved in a non-volatile memory device every time the parameter is changed. For station list and current stations, the parameters are updated after the current action has been completed (i.e. after a station scan has completed, or after a tuned station is changed). This means that if you power down during Scanning or Station tuning, the Station list may be lost. On the following power up, the Station list will be empty and the parameters will return to the default values. 20

21 Power on and Tuning On the very first power on, or following a factory reset (or if a factory reset was carried out prior to power down), the radio operates as shown in the following flow diagram. Stage 1. The LCD screen displays a welcome message. Stage 2. The receiver scans to find all the stations available. Stage 3. When the stations are acquired, the receiver tunes to the first station found in the alphanumeric list of stations that it has compiled. Stage 4. The station name is displayed and the first line of its broadcast parameters are displayed. The first line comprises the scrolling Digital Label (DLS). This information is broadcast along with the audio and contains information relevant to the current broadcast content and technical data regarding the playing station. 21

22 Adjust the volume to a comfortable listening level using the Central Navigator button. If no stations can be found (unsuccessful) then the screen at stage 3 will be displayed for a short time, followed by the screen at stage 4. On subsequent power-ups the radio will acquire/tune to the last station selected and the icons will reflect the system status, as shown below. There are two items in the presented menu list, MANUAL TUNE and AUTOSCAN. The operation of these features is described on page 29 under Menu settings. 22

23 Tuned and Playing Once the station is tuned and playing, the Station name will appear on the upper line of text. The bottom line can be customised as described below. The information that can be displayed on the second line comprises: 1Xtra : BBC Program type : Other music Multiple name : BBC National DAB Date : Channel & Frequency: 12B MHz Bitrate mode : 128kbps stereo Signal Error : 2 The DLS information is usually longer than 16 characters and scrolls in an apparent continuous loop, until updated by the broadcaster. Press the info button to step through and display the broadcast text information for each of the options in the list above. This will be displayed on the bottom line of the display. 23

24 Features Station selection and navigation While one station is playing, you can scroll through other located stations using the Central Navigator - scroll button. Press the right and/or left sides of the Central Navigator button to step through the acquired station list. Once the end of the list is reached, it will automatically wrap around to the start of the list. The arrow symbols that appear at either end of the lower text line when this function is invoked, indicate that there are other stations in the available list. To change to the station displayed on the lower line, press Select. The radio will tune to this station. If no station is selected or the interval between button presses is greater than 7 seconds the function will time out and the display will revert to play mode. An eight-character version of the station name is displayed when scrolling this station list. Refer to the flow chart on this page. 24

25 Select button signal function The select button has a second function in addition to the one where, in normal station navigation, it confirms the highlighted selection. When SELECT is pressed while the radio is in play mode the lower text line displays a graphical representation of the received signal level. The minimum signal level required is imposed on this bar array and takes the form of an open box. The bars indicate the current signal level and the central highlighted bar is the minimum signal required. The signal strength icon on the screen continues to be displayed at the same time. Press SELECT again to cancel the signal level function. Volume The volume can be adjusted using the Central Navigator button. Push it forwards to increase the volume and backwards to decrease the volume. Each time you press the UP/DOWN button, the volume increments/decrements by one preset step. Two presses of the button result in the addition or removal of a bar from the volume level icon at the top left corner of the screen. A continuous press in one direction continues to increment/decrement the volume until the button is released. No other changes to the display occur. The volume can only be adjusted when a station has been acquired and is playing. When the radio is scanning or selecting stations the audio will be muted but no change will be made to the displayed volume icon. 25

26 Preset You can store up to ten stations using the preset function. To access the preset function press the preset button. A list of the ten presets becomes available on the bottom line of the screen. To select and play a preset scroll the list until you find one you wish to listen to and then press select to tune to the stored preset. The flow diagram is shown right. The arrow symbols that appear at either end of the lower text line when this function is invoked, indicate that there are other available preset channels which can be scrolled through. An allocated preset will show the station name followed by the preset number, or if there is no station allocated then PRESET 1 FREE is displayed instead. To assign a preset channel to a radio station, carry out the following: With the radio playing the station you would like to assign to a preset channel, press the preset button. 26

27 The lower text line shows the first preset channel of the Preset list, and its status i.e. the name of the station it is allocated to number, or whether it is empty. Both display the preset channel number, 1 to 10. Use the Central Navigator button (Left or Right) to scroll through the list until you find an empty preset channel or a preset channel you would like to overwrite. Press and hold the preset button for 2 seconds until the screen displays confirmation that the preset has been saved. If you are browsing the available stations (Central Navigator Left/Right buttons) an assigned preset is indicated by the preset channel number displayed at the end of the lower text line containing the station name. 27

28 EQ The EQ function is called via the eq button. The current equalisation is represented by the EQ icon on the screen. To change to another setting, press the eq button. The next equalisation setting is applied and the EQ icon is updated accordingly. Continue to press the eq button until you reach the desired equalisation from the following : MBass, Monitor, Studio, Club, Arena and Flat. The EQ setting is saved on power down. The setting saved at power down is applied the next time the radio is used. 28

29 Menu settings The menu function allows you to scroll the system settings and make certain changes to them as follows. Press the menu button to access the list of system settings: Station Order Manual tune Autoscan local Software version Use the Central Navigator button (LEFT / RIGHT) to scroll to the option you require and press SELECT to enter the sub-menu. Continue to navigate the sub-menus (first three in the list above) to reach the required function and press SELECT to enter the function. Station order As you use the radio, it automatically compiles a full list of the stations found, in all the locations it has used. Using the station order function can change the way this list is displayed on the LCD screen. The station order function is accessed by scrolling to the Station order option in the list using the Central Navigator buttons and then pressing the SELECT button. The options accessed in a similar way allow you to choose the content and order of the station list in the following ways. Alphanumeric. Arranged in Number - Alphabetical order. Active station This lists those stations for which a signal can be acquired and places them at the top of the list in alphanumeric order. Other stations, which are in the list but for which a station cannot be acquired, are appended in alphanumeric order. Reduce stations Removes stations from the list for which a station cannot be acquired (those with a? against them). Fav. stations Identifies the ten most listened to stations and places them at the top of the list of stations. 29

30 When this station order is selected the heart icon will be displayed on the screen. When the station order is set to Favourites, and you browse the station order list, an additional option called Favourite Presets becomes available. This automatically allocates your favourites to the presets and overrides any presets previously allocated. 30

31 Autoscan The Autoscan function is accessed by scrolling to Autoscan local on the primary menu list using the Central Navigator button (LEFT/RIGHT) and then pressing SELECT. This tells the radio to rescan for available stations. A scanning screen will appear and a progress bar displayed. Audio is suspended and on the right hand side a number will appear indicating the number of stations found. On completion, the radio will play the station you were listening to previously. Manual tune This function invites the selection of a channel that the radio will try and tune to. The Manual tune function is accessed by scrolling to Manual tune on the primary menu list using the Central Navigator button (LEFT / RIGHT) and then pressing SELECT. Use the Central Navigator button (LEFT/ RIGHT) to scroll to the desired band. Press SELECT. The screen displays the signal strength bar.

34 Care & Maintenance Cleaning Wipe with a soft cloth. If the radio is very dirty, dampen a cloth with a weak solution of detergent and water and then wipe clean. Dry thoroughly with a clean soft cloth. 34

35 Help & Advice The radio is not working and there is nothing displayed on the screen Make sure the Power button has been pressed. Check the condition of the batteries. Check that the batteries have been inserted and they are correctly orientated. No sound can be heard in the headphones Make sure the headphone jack is inserted fully. Adjust the volume level. Poor radio reception Check that the signal strength monitoring shows a suitable signal level is being received. If autoscan does not find a station, check the signal strength by selecting Manual tune. Make sure the aerial (the headphone lead) is positioned for best signal reception. Use the signal level indicator to find the optimum aerial placement. Radio locks up If the radio is operational but the buttons do not appear to work, check that the lock button is set to the unlock position. If the buttons still do not work, carry out a factory reset (see page 32). If this does not resolve the problem, remove the batteries for one minute then replace and try again. Note When the radio is mobile, such as when you are travelling in a car or on a train for example, the signal required to acquire a station will need to reach the minimum signal level or even exceed it, whereas if in static useage, stations can be received when the signal is below this level. Check with the signal strength function accessed using the SELECT button whilst the radio is in play mode. 35
