SECTION 2 GENERAL DESCRIPTIONS 2.1 Multi-band : CMD-J16 support E-GSM 900 and DCS 1800 multi-band functionality. For the use in Europe and in other countries worldwide, ETSI has specified GSM standards into two frequency bands. That is the 900-MHz and 1800-MHz band and is usually referred to as GSM900 and GSM1800 (formerly DCS1800). While the 900-MHz band has 124 channels (extended version: 175), the 1800-MHz band with its 375 channels provides a three-times higher capacity.
2.2 Radio Frequency Power Levels: Between the DCS 1800 and both GSM Systems are differences regarding the power level. DCS 1800 basically needs lower power levels. If the performance of a MS for GSM system was certified of 2W (Power Class 4), then in the DCS-1800 system it is only 1W (Power Class 1). There are also reduced BTS power levels due to microcell applications, which means instead of the 40W (Power Class 4) in the GSM system DCS 1800 needs only 20W (Power Class 1).
2.5 Battery Charging There is no charging circuitry in the battery pack. The CMD-J5/J16 has complete charger function internally. The telephone can be charged only with the battery connected the phone. This situation can be sub-divided into two situations: the phone is on or off. It can be charged with the AC Adapter, Travel Charger or Cigar Lighter Charger. The battery symbol is used to indicate the charging, and to indicate when the battery is fully charged.
2.8 Accessory Interface The table explains what kind of pins the phone supplies to the different accessories.

SECTION 4 DISASSEMBLING / TESTING 4.1 Disassembly IMPORTANT NOTE : The IMEI number is the electronic identification of the hardware, which is stored electronically. There should be no discrepancy between the number on the sticker and the number within the set memory allowed. In case of replacing the lower cabinet it is to make sure that the IMEI Sticker mounted on the lower case (visible from the battery compartment) will be replaced to the new housing part as well.
LCD IMPORTANT: Do not detach the shield case from the main board CABINET LOWER Re-assembly procedure : To re-assemble the unit, apply the reverse order of the above mention disassembly procedure.
4.2 Interface to GSM-Tester Test Set Up for CMD-J5/J16 Level 1 Testing CMD- J 5/J 16 + Battery Pack + Test SIM Card Service Test Connector RF output : SMA jack* STC-03 Part No. 3-224-391-01 RF input Connector * GSM – TESTER This unit acts as a base station providing all the necessary GSM signalling requirements and provides GSM signal measuring facilities as well.
Level Test Procedure with GSM TESTER recommendation: • • Simulate GSM call processing – to check the functionality of transmitting and receiving audio signals of loudspeaker and microphone. Basic GSM transmission & reception parameter testing – to ensure that handset’s performance compiles with standard GSM specification. 4.
Section 5 PROGRAMMING INSTRUCTIONS 5.1 Requirement • PC (486 type or higher) with Microsoft “Windows” Operating System • One COM-port free for usage • The Data Transfer Cable (p/n 1-757-348-11) PREPARATION FOR SOFTWARE UPDATE DATA TRANSFER CABLE 5.2 Hardware set-up • Copy all the files to the PC (define own directory). • Connect the Data Transfer Jig to the PC COM-port (COM 1 or COM 2) and the CMD-J5/J16 external connector.
• Select “file”/”Settings…” and check if the settings for the “Com Port”and “Speed” are correct. − The FlashLoader automatically detects all available Com ports on the PC. (COM 1 or COM 2) − Baud rates up to 812500bps will be supported, but standard PCs, unless it is correctly customised (i.e. with a Fast Serial Board), will not support Baud rates > 115200bps. − The default values are COM1 115200 • Click on the “Load” button and select an SRE file for downloading.
