1 Introduction
The C25 is the first dualband handset (GSM-900 and GSM-1800) in the C-class.
The C2588 is a special version for the asian market featuring a graphic display instead of the
alphanumeric C25 display.
The repairs for C25 and C2588 are identical unless otherwise noted.
Lately a new version of the C25 has been introduced. This version has the main processor
HiGold version 4.3 of the S25(88). Internally this C25 is therefore called C25V4. The level
2.5 parts are identical to the old C25 version.
This manual is intended to help you carry out repairs on level 2.5, meaning limited
component repairs. Failure highlights are documented and should be repaired in the local
workshops.
It must be noted that all repairs have to be carried out in an environment set up according to
the ESD (Electrostatic Discharge Sensitive Devices) regulations defined in international
standards.
