3.7 Hot Key Dial Source List
The source for Hot Key Dial Numbers is normally ‘Phonebook’ or ‘Service Dial Numbers’. For some OEMs it may be a
requirement to store these numbers in the EEPROM. When the source is the EEPROM and the telephone software is updated,
the source numbers may be lost. Also, if the user changes the source of the Hot Key Dial numbers, it will not be possible to
redirect the source back to the EEPROM. However, in the event that an OEM would like the Hot Key Dial source to be stored
in the EEPROM, it is unlikely that the user will have the option to change the Hot Key Dial source.

3.13SIM Personalisation
3.13.1Introduction
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 GD30/GD50 contains a SIM that is from a different
source it will display the message “SIM ERROR” when switched on. This personalisation of GD30/GD50 is sometimes referred
to as SIM lock or SIM latch.
3.13.2Testing
To test a personalised GD30/GD50, 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.
3.13.3Personalisation Function
Personalisation is activated during manufacture and then enabled at a later stage. 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 an illegal SIM and the
sixteen digit Control Key (CK) is known. When enabled the CK is withheld from the user and cannot be read, for security
reasons.
There are two special key sequences to enter the enable/disable menu:
Key sequence Notes
7 4 6 B B Can only disable personalisation.

4.1 General
This section provides disassembly and reassembly procedures for the main components of GD30 and GD50 telephones.
These procedures MUST be performed by qualified service personnel, at an authorized service centre.
The following warnings and precautions MUST be observed during ALL disassembly/reassembly operations:
WARNING
The equipment described in this manual contains polarised capacitors utilising liquid electrolyte. These devices are entirely
safe provided that neither a short-circuit nor 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.
Caution
The equipment described in this manual contains electrostatic sensitive devices (ESDs). Damage can occur to these
devices if the appropriate handling procedure is not adhered to.
4.1.1 ESD Handling Precautions
A working area where ESDs may be safely handled without undue risk of damage from electrostatic discharge, must be
available. The area must be equipped as follows:
Working Surfaces – All working surfaces must have a dissipative bench mat, SAFE for use with live equipment, connected
via a 1M2 resistor (usually built into the lead) to a common ground point.
Wrist Strap – A quick release skin contact device with a flexible cord, which has a built in safety resistor of between 5k2 and
1M2 shall be used. The flexible cord must be attached to a dissipative earth point.
Containers – All containers and storage must be of the conductive type.
