1 Introduction

ME/S45 product family, consists of 2 different dualband handsets (GSM-900 and GSM-

1800), which can easily be distinguished from the second block of the partnumber printed on
the IMEI label.

This product is developed with different HW in the radio part, which can not be distinguished
on the IMEI label. The HITACHI (HIT) as the INFINEON (IFX) boards have the same logic
part. For all described Level 2.5 components you find a board type identification in the
document as shown below.

HIT component used only in HITACHI version
IFX component used only in INFINEON version
HIT/IFX component used in HITACHI and INFINEON versions

Partnumber on IMEI label:

1) ME45: S30880-S4600-#xxx

2) S45: S30880-S4500-#xxx

,while # may be any letter (A-Z) and xxx may be any number from 100, 101, 102....

3) 3618/ME45 S30880-S4600-#xxx

4) 6618/S45 S30880-S4500-#xxx

,while # may be any letter (A-Z) and xxx may be any number from 800, 801, 802....

The information in this manual applies to both types, ME45 and S45, unless otherwise noted.

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.

If you have any questions regarding the repair procedures or technical questions about the
spare parts do not hesitate to contact our technical support team in Kamp-Lintfort, Germany:

6.2.3 Component Information:

The Antenna Connector is a mechanical switch operated by the RF plug of a carkit.
Normally the RF signal goes to and comes from the internal antenna. Whenever an RF plug
is plugged into the antenna connector the connection to the internal antenna is opened and
the connection to the external antenna socket is made. When the antenna connector is
blocked without RF plug the connection to the internal antenna is also opened. See drawing
below.

11.4.1.1 General Information

The purpose of the 150µF capacitor C906 is to buffer the battery
voltage. This is especially necessary during the Tx burst, when a high
current is taken from the battery.
If the cap is defective it is most likely burned and may cause a short
from the battery to ground.

11.4.1.2 Diagnosis

Check the status of the capacitor with a multimeter.

11.4.1.3 Repair by component change

Use soldering iron to remove defective capacitor.
Avoid excessive heat!
Watch surrounding components!!

IMPORTANT: DON`T USE A HOT AIR BLOWER FOR SOLDERING!

(The new component could be damaged by overheating)

Resolder new capacitor afterwards.
