Introduction

This Service Repair Documentation is intended to carry out repairs on Siemens

repair up to level 2. The described failures shall be repaired in Siemens authorized

local workshops only.

All repairs have to be carried out in an ESD protected environment and with ESD

protected equipment/tools. For all activities the international ESD regulations have to be

considered.

Assembling/disassembling has to be done according to the latest CL75 Level 2 repair

documentation. It has to be ensured that every repaired mobile Phone is checked

according to the latest released General Test Instruction document (both documents

are available in the Technical Support section of the C-market).

Check at least weekly C-market for updates and consider all CL75 related Customer

1. GPRS (General Packet Radio Service)

GPRS is a new non-voice value added services that allows information to be sent

and received across a GSM mobile telephone network. It supplements today’s Circuit

Switched Data (CSD) and Short Message Services (SMS). GPRS involves overlaying

a packet based air interface on the existing circuit switched GSM network. This gives

the option to use a packet-based data service. The information is split into separated

but related “packets” before being transmitted and reassembled at the receiving end.

Theoretically, maximum speeds of up to 171.2 kilobits per second (kbps) are

achievable with GPRS using all eight timeslots at the same time. This is about 3

times as fast as the data transmission speed possible over today’s fixed

telecommunications networks and 10 times as fast as current Circuit Switched Data

services on GSM networks.

Example: Cell with 1 Frequency channel:

1 physical channel for signaling, 4 physical channels for Circuit switched and 3 physical

channels for Packet switched.

5. CL75 Disassembly

Note: ESD concept; the internal circuits will be more susceptible to ESD during the

housing exchange. The construction of the internal block is designed, in the best

possible way, to protect the circuit against sparks.

The keypad must be completely closed to prevent any occurrence of an ESD

disruptive discharge.

It is a requirement for the service personnel to observe ESD protection rules while

performing service on CL75.
