WARNINGS AND CAUTIONS

WARNING

The equipment described in this manual contains polarized 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 devices (ESDs). Damage can occur to these devices if the appropriate
handling procedure is not adhered to.

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 1MΩ 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 approximately 1MΩ
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.

Batteries

This equipment may contain 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.

OPERATING INSTRUCTIONS

3.6. Incoming Call Line Identification (CLI)

When a call is received the last 6 digits of the CLI information is matched with the phonebook. Therefore an incoming call could
match to the wrong phonebook entry.

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.

3.10. Troubleshooting

The user is given the following information and advised to contact the dealer if the problems persist:

Problem Cause Remedy

Telephone will not switch
on

Extremely short battery
life for a new battery pack

Short battery life for an
old battery pack

Short battery life for Ni­MH battery pack

The battery level indicator

does not light when

charging

Calls cannot be made The telephone is locked. Unlock the telephone (Menu: Security: Phone Lock).

Calls cannot be made
from Fixed Dial Store

Calls cannot be received The telephone is not switched on. Switch the telephone on.

Emergency calls cannot
be made

Telephone numbers
cannot be recalled

The network in use and the condition of the
battery pack can affect battery life.

The battery pack was worn out. Replace with a new one.

The life of the battery pack is affected by
improper charging, this is inherent in all Ni­MH batteries.

If a battery is deeply discharged it will take a
short time before there is sufficient power in
the telephone to light the battery level
indicator .

Outgoing calls are barred. Disable the outgoing call barring (Menu: Security: Call Bar).
The telephone is not registered to a network. Move to a coverage area and operate the telephone after it

Incoming calls are barred. Disable the incoming call barring (Menu: Security: Call Bar).
The telephone is not registered to a network. Move to a coverage area and operate the telephone after it

User’s phone is not in a GSM coverage area.

The telephone is locked. Unlock the telephone (Menu: Security: Phone Lock).
Fixed Dial is switched on. Switch off Fixed Dial (Menu: Security: Fixed Dial).

Check that the battery pack is fully charged and correctly
connected to the telephone.

Avoid areas of poor reception. Ensure batteries are fully
charged. Additionally, for NiMH batteries, ensure batteries are
also discharged fully before recharging.

To maintain maximum performance, always use until the Low
Battery Warning appears and then fully recharge the battery
pack. To revive a Battery Pack, use the telephone until the
Low Battery Warning appears and then fully recharge three
times. However, if the battery life still is short, the battery pack
has eventually worn out. Replace with a new one.

Leave to charge for several minutes in temperatures between
+5°C and +35°C.

Check that the antenna symbol is displayed. Move to a

coverage area and operate the telephone when the antenna
symbol is displayed.

3.13. SIM Personalisation

3.13.1 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 GD52/ GD92/ GD92C 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.

3.13.2 Testing

To test a personalised GD52/ GD92/ GD92C 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.

3.13.3 Personalisation 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:

DISASSEMBLY / REASSEMBLY INSTRUCTIONS

4 DISASSEMBLY / REASSEMBLY INSTRUCTIONS

4.1. General

This section provides disassembly and reassembly procedures for the main components of GD52, GD92 and GD92C
telephones.

These assemblies MUST be performed by qualified service personnel at an authorised service centre.

The following Warnings and Cautions MUST be observed during all disassembly / reassembly operations:

WARNING

The equipment described in this manual contains polarised capacitors uitilising 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 WAR N ­ING 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 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 handled safely 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 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 an integral safety resistor of between 5k2 and 1M2, shall
be used.

Containers

All containers and storage must be of the conductive type.

4.2. Disassembly

4.2.1 Case Removal (GD52)

1. Remove the battery cover by pushing it towards the base of the phone and then lifting it away from the case.
