13 1.4 Safety precaution The following afety precaution mut be oberved during all phae of the operation, uage, ervice or repair of any cellular terminal or mobile incorporating MC39i. Manufacturer of the cellular terminal are advied to convey the following afety information to uer and operating peronnel and to incorporate thee guideline into all manual upplied with the product. Failure to comply with thee precaution violate afety tandard of deign, manufacture and intended ue of the product. Siemen AG aume no liability for cutomer failure to comply with thee precaution. When in a hopital or other health care facility, oberve the retriction on the ue of mobile. Switch the cellular terminal or mobile off, if intructed to do o by the guideline poted in enitive area. Medical equipment may be enitive to RF energy. The operation of cardiac pacemaker, other implanted medical equipment and hearing aid can be affected by interference from cellular terminal or mobile placed cloe to the device. If in doubt about potential danger, contact the phyician or the manufacturer of the device to verify that the equipment i properly hielded. Pacemaker patient are advied to keep their hand-held mobile away from the pacemaker, while it i on. Switch off the cellular terminal or mobile before boarding an aircraft. Make ure it cannot be witched on inadvertently. The operation of wirele appliance in an aircraft i forbidden to prevent interference with communication ytem. Failure to oberve thee intruction may lead to the upenion or denial of cellular ervice to the offender, legal action, or both. Do not operate the cellular terminal or mobile in the preence of flammable gae or fume. Switch off the cellular terminal when you are near petrol tation, fuel depot, chemical plant or where blating operation are in progre. Operation of any electrical equipment in potentially exploive atmophere can contitute a afety hazard. Your cellular terminal or mobile receive and tranmit radio frequency energy while witched on. Remember that interference can occur if it i ued cloe to TV et, radio, computer or inadequately hielded equipment. Follow any pecial regulation and alway witch off the cellular terminal or mobile wherever forbidden, or when you upect that it may caue interference or danger. Road afety come firt! Do not ue a hand-held cellular terminal or mobile when driving a vehicle, unle it i ecurely mounted in a holder for handfree operation. Before making a call with a hand-held terminal or mobile, park the vehicle. Handfree device mut be intalled by qualified peronnel. Faulty intallation or operation can contitute a afety hazard. MC39i_HD_V01.02 Page 13 of

14 SOS IMPORTANT! Cellular terminal or mobile operate uing radio ignal and cellular network cannot be guaranteed to connect in all condition. Therefore, you hould never rely olely upon any wirele device for eential communication, for example emergency call. Remember, in order to make or receive call, the cellular terminal or mobile mut be witched on and in a ervice area with adequate cellular ignal trength. Some network do not allow for emergency call if certain network ervice or phone feature are in ue (e.g. lock function, fixed dialing etc.). You may need to deactivate thoe feature before you can make an emergency call. Some network require that a valid SIM card be properly inerted in the cellular terminal or mobile.

Table 3: Overview of operating mode Mode Normal operation Power Down Alarm mode Function GSM / GPRS SLEEP GSM IDLE GSM TALK GPRS IDLE GPRS DATA Variou powerave mode et with AT+CFUN command. Software i active to minimum extent. If the module wa regitered to the GSM network in IDLE mode, it remain, in SLEEP mode, regitered and pageable from the BTS. Power aving can be choen at different level: The NON-CYCLIC SLEEP mode (AT+CFUN=0) diable the AT interface. The CYCLIC SLEEP mode AT+CFUN=5, 6, 7 and 8 alternatingly activate and deactivate the AT interface to allow permanent acce to all AT command. Software i active. Once regitered to the GSM network, the module can be paged from the BTS and i ready to end and receive. Connection between two ubcriber i in progre. Power conumption depend on network coverage individual etting, uch a DTX off/on, FR/EFR/HR, hopping equence, antenna. Module i ready for GPRS data tranfer, but no data i currently ent or received. Power conumption depend on network etting and GPRS configuration (e.g. DRX etting) GPRS data tranfer in progre. Power conumption depend on network etting (e.g. power control level), uplink / downlink data rate and GPRS configuration (e.g. ued multilot etting). Normal hutdown after ending AT^SMSO command or emergency power off via /EMERGOFF pin. The Power Supply ASIC (PSU_ASIC) diconnect the upply voltage from the baeband part of the circuit. Only a voltage regulator in the PSU-ASIC i active for powering the RTC. Software i not active. The erial interface i not acceible. Operating voltage (connected to BATT+) remain applied Retricted operation launched by RTC alert function while the module i in Power Down mode. In Alarm mode, the module remain deregitered from the GSM network. Limited number of AT command are acceible. See alo Table 7 and Table 8 for the variou option of waking up the GSM engine and proceeding from one mode to another. MC39i_HD_V01.02 Page 20 of

21 3.2 Power upply The power upply of MC39i ha to be a ingle voltage ource in the range of V BATT+ = 3.3V...4.8V. It mut be able to withtand a ufficient current in a tranmiion burt which typically rie to 2A (ee Chapter 5.4.1). Beyond that, the power upply mut be able to account for increaed current conumption if the module i expoed to inappropriate condition, for example antenna mimatch. 5 BATT+ pin and 5 GND pin are available on the ZIF connector. The RF power amplifier i driven directly from BATT+. All the key function for upplying power to the GSM engine are handled by an ASIC power upply. The ASIC provide the following feature: Stabilize the upply voltage for the GSM baeband proceor and for the RF part uing linear voltage regulator. Control the module' power up and power down procedure. A watchdog logic implemented in the baeband proceor periodically end ignal to the ASIC, allowing it to maintain the upply voltage for all MC39i component. Whenever the watchdog pule fail to arrive contantly, the module i turned off. Deliver a regulated voltage of 2.9V acro the VDD pin. The output voltage VDD may be ued to upply your application, for example, an external LED or level hifter. However, the external circuitry mut not caue any pike or glitche on voltage VDD. Thi voltage i not available in POWER DOWN mode. Therefore, the VDD pin can be ued to indicate whether or not MC39i i in POWER DOWN mode. Provide power to the SIM interface. Pleae refer to Table 4 for a decription of the power upply pin and their electrical pecification. MC39i_HD_V01.02 Page 21 of
