CHAPTER 1 - FOREWORD
This document is common to all phones in the SAGEM. It is composed of independent sheets:
−Symptom sheets = Symp Sheet XX
−Test and check sheet = Test Sheet XX
−Maintenance procedure sheet = Proc Sheet X XX
The applicability of a procedure is indicated in the independent sheets title block:
−All types = GSM 850/900, GSM 1800/1900 and dual band.
These sheets are updated from time to time in Technical Information Bulletins (TIB).
The information contained in this document is non-contractual, since phone characteristics can change.
Phones are managed based on SAGEM handset codes; any order for spare parts must refer to these codes
(typical code 25 xxx xxx-x).
1.1 HOW TO USE THE SITE TECHNICAL DOCUMENTATION
This is a modular document. Each sheet is unique and independent. In some cases several sheets may
have to be used in order to determine the complete procedure to be applied.
A troubleshooting chapter (chapter 3) is provided and is sorted according to the type of reported fault, to
determine the maintenance procedure to be carried out.
These sheets describe the procedure to be followed. They refer to test sheets or removal and replacement
maintenance sheets. Maintenance ,executed by the repair centre, terminates either by returning the product
to the customer, or by dispatching it to level 3 maintenance (return to factory).

2.6.1.2 Description
Li-ion type batteries are used. They are rechargeable using:
-mains power supply modules,
Batteries caution use:
•Store the batteries in a dry and cool place (excessive cold and heat damage the batteries reliability).
•They must never be stored in bulk, even the rejects, to avoid any short circuits.
•Do not dismantle the battery packs. (Li-Ion regulations).
•Only use original mains power supply module.
•All the out of order batteries must be returned to SAGEM.
