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).
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).
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.
2.8 Accessory Interface The table explains what kind of pins the phone supplies to the different accessories. Charge Pins √ √ Charger Connector layout Connector view from base of phone The connector comprises the following pins: Audio Audio In, Audio Out and Audio GND: Audio IN: Is a single ended input with a maximum sensitivity of 365 mVrms.

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.

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 Use special RF-Adapter for connection of STC-03 to your GSM –Tester ! CMD- J 5/J 16 Battery Pack Test SIM Card Service Test Connector RF output : SMA jack STC-03 Part No.
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.
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. • Attach battery pack to CMD-J5/J16; the CMD-J5/J16 is powered up from the battery pack.
• Click on the “Load” button and select an SRE file for downloading. − The CMD-J5/J16 software is located in the J5.SRE file. − Any other SRE file is either only needed for the program itself, or can be a personal data file.
AUX_DAC signals 6.1.1 General RF Indications The radio part of the CMD-J5/J16 handles the air interface according to the GSM specifications. It is the main contributor for the dualband functionality for E-GSM 900 and DCS 1800. Receiver The receiver consists of two separated RF paths for GSM and DCS 1800 each.
It is a chip that implements: the digital baseband processes of the CMD-J5/J16 and combines a Digital Signal Processing (DSP) with its program and data memories, a Micro-Controller core with emulation facilities and an internal RAM memory, a clock squarer cell, several compiled ports and equivalent CMOS gates.
IC 2 IC 2 is the platform of the A/D-D/A converter for the interfacing and processing of baseband I/Q signals and voice signals. It includes: the complete set of baseband functions to perform the interface and processing of voice signals, interface for processing of baseband components as In Phase (I) and Quadrature (Q) signals which support single slot and multi slot mode, associated auxiliary RF control features,...
