1INTRODUCTION

1.1. Purpose of this Manual

This Service Manual contains the information and procedures required for installing, operating and servicing the Panasonic

GSM Personal Cellular Mobile Telephone system operating on GSM Digital Cellular Networks.

WARNING

The equipment described in this manual contains polarised capacitors utilising liquid electrolyte. These devices are

entirely safe provided that neither a short-circuit or a reverse polarity connection is made across the capacitor terminals.

FAILURE TO OBSERVE THIS WARNING COULD RESULT IN DAMAGE TO THE EQUIPMENT OR, AT WORST,

POSSIBLE INJURY TO PERSONNEL RESULTING FROM ELECTRIC SHOCK OR THE AFFECTED CAPACITOR

EXPLODING. EXTREME CARE MUST BE EXERCISED AT ALL TIMES WHEN HANDLING THESE DEVICES.

WARNING

A Naphthalene-based resin paste is used to bond underfill components on this phone. When heated, this paste may give

off traces of Naphthalene.

Therefore, it is recommended that work on the PCB be carried out in a well-ventilated area, especially when using hot air

blowers or soldering irons.

The following components are bonded using the paste:.

CALYPSO+ (U100).

SYREN (U120)

Bluetooth IC (U500)

Caution

The equipment described in this manual contains devices sensitive to electrostatic discharge (ESD). Damage can occur

to these devices if the handling procedures described in this manual are not adhered to.

Caution

This equipment contains an internal battery in addition to the external battery packs. These batteries are recyclable and

should be disposed of in accordance with local legislation. They must not be incinerated, or disposed of as ordinary

rubbish.

Caution

The equipment uses a Printed Circuit Board PCB manufactured using Lead Free (PbF) solder. The procedures described

in this manual should be adhered to when repairing these items.

Press: * # 0 6 #

To identify the software version installed on the phone:

Press: * # 9 9 9 9 # within five seconds of switching on.

3.7. SIM Personalisation

3.7.1 Introduction

SIM personalisation will limit the use of the telephone to a single SIM, a SIM supplied by one Network / Sub-network / Service

Provider or a SIM purchased by a company (corporation). If a personalised handset contains a SIM that is from a different

source, it will display the message “SIM ERROR” when switched on. This personalisation is sometimes referred to as SIM

lock or SIM latch.

3.7.2 Testing

To test a personalised handset when the user has not supplied the SIM, a SIM configured for test purposes (e.g. test SIM or

soft SIM) should be used. The mobile will recognise that the SIM is for testing purposes only and operate as normal.

3.7.3 Personalisation Function

Personalisation is activated during manufacture. Enabling / disabling is available by entering a special key sequence

immediately after power on. Once the enable / disable menu is shown it is possible to select the type of personalisation. When

personalisation is enabled it is only possible to disable it if the mobile contains a SIM and the 8 or 16 digit Control Key (CK) is

known. For security reasons, when CK is enabled, it cannot be read by the user.

There are two special key sequences to enter the enable / disable menu:
