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:
