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.

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 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).

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.

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.

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.

6.1. Introduction

This section provides information on testing GD52, GD92 and GD92C telephones. The layout is as follows

1. Section6.2 ALIVH PCBs: Description and repair procedures.

2. Section6.3 External testing: describes equipment requirements and general set up procedure.

3. Section 6.4 Complete Unit Test Setup: describes how the items of test equipment are used together and general set up
procedure.

4. Section6.5 Channel box test commands: provides detailed explanation of the different commands available using the test
equipment and channel-box software.

5. Section6.6 Adjustment mode: describes adjustments available on the handheld unit.

6.2. Any-Layer Interstitial Via Hole (ALIVH) PCBs

CAUTION

The GD52, GD92 and GD92C telephone handsets use an ALIVH PCB assembly, the substrate of which is hydrophilic. To
avoid damaging the ALIVH PCB, the specialist equipment and procedures described below must be employed when
replacing suspect or faulty components.

6.2.1. General Information

To reduce overall size and provide enhanced speech and data performance, an Any-Layer Interstitial Via Hole (ALIVH) PCB
is used in GD52, GD92 and GD92C handsets. ALIVH PCBs are multi-layer boards which have an IVH structure in all inter­layers and can provide an inter-layer connection immediately under the land of a component. In addition, the PCB has no
through holes and any number of layers can be interconnected.

As the specification and performance characteristics of ALIVH PCBs differ from that of conventional multi-layered boards,
special attention is required when handling and repairing these assemblies.

Moisture Absorbency
The ALIVH PWB is more absorbent than a conventional PCB because of the nature of its material. Its aramid substrate is

hydrophilic, i.e. it absorbs moisture from the air. If, after having absorbed moisture, the ALIVH PWB is submitted to re-flow or
repair process, moisture in the board can suddenly evaporate and cause vapour explosion.

Copper Foil Peel Strength (Land Detachment Resistance)
The ALIVH PCB is slightly less resistant to copper detachment force than conventional boards. Therefore, it is necessary to

ensure that solder is melted sufficiently before a component is removed from the board.
Warping Property
The ALIVH PCB has a smaller Young's Modulus and is therefore more pliant than conventional boards. It is important that the

ALVIH PCB is not bent when component placement is performed.

6.2.2. Repair Procedures

To prevent problems caused by moisture absorption, it will be necessary to perform dehydration of ALIVH PCBs in a suitable
oven or similar heating device prior to repair. The boards should be heated at 85°C for a duration of at least ten hours.

The repair should also be performed under the following conditions:

6.2.2.1. Soldering Iron

The temperature of the tip of the soldering iron should be 350°C ±10°C for an application time of five seconds or less.
Removal and re-mounting of components should be performed only once at any component position.

Note: To avoid land detachment, do NOT apply excessive force on the soldering iron when heating the board.

Ensure that the solder has melted sufficiently to allow component removal without damaging the board.

MCUK000601C8 Section 6 Issue 1
Service Manual – 31 – Revision 0

TEST AND MEASUREMENT

6.2.2.2. Hot-Air Blower

The blower air temperature should be at:
295°C ±5°C for an application time of 120seconds or less,

or:
395°C ±5°C for an application time of 30seconds or less.
Removal and re-mounting of components should be performed only once at any component position.

Note: To avoid land detachment, do NOT apply excessive force on the soldering iron when heating the board.

Ensure that the solder has melted sufficiently to allow component removal without damaging the board.

6.2.2.3. Re-flowing / Re-touching

1. Re-touching by soldering iron:
HAKKO 928 soldering iron is recommended.
900S-T-B tip for thicker solder joints and 900M-T-LB tip for thinner solder joints are recommended

2. Tip temperature/time
Normal pad : 325±10°C, less than five seconds
Large Pad : 400±10°C, less than five seconds

3. Pressure at solder tip

· Weight of soldering iron, (50gm) + 100gm to 150gm

· Do not exert pressure in the horizontal direction

4. Retouching small components
Pinch the component using two soldering irons and retouch within four seconds

6.3. External Testing

6.3.1. General Information

The handset can be connected to a compatible personal computer for electronic adjustment and fault diagnosis. This section
provides a description of the equipment required to perform those tasks.

Testing and adjustment of the handheld unit can be performed with the outer case in place and the cradle connected. For in­depth fault finding the unit should first be disassembled, as detailed in Section4, and then the PCB Repair Jig used to connect
the PCBs together externally as they would be found in normal use. Fault tracing can then be performed on the PCBs using
suitable test equipment, such as spectrum analysers and oscilloscopes.

The unit must now be tested and calibrated for both frequency bands (900MHz and 1800MHz).

6.3.2. Jigs and Tools

Interface Box (Part No. IFB003 / IFB004)

The Interface box provides:
IFB003: Voltage regulation for +7.2V, +5.6V or 4.8V DC outputs. The +7.2V switch setting is used as a supply to Li-Ion type

batteries (compatible for other products), the 5.6V switch setting is used for PCB testing and the 4.8V switch setting is used
for testing the complete unit.

Interface Box IFB004 is a later version that provides +4.8V, +7.2V and +8.2V DC outputs. It also allows selection of external
power via the Interface cable.

RS 232 interface. Ensures that the Unit Under Test is supplied with the correct signal levels and format.

6.6.4. I and Q Values

NOTE: With the I, Qch adjustment procedures, the transmitter must be set to Power Level 5 (this represents the worst

case of non-linearity) so care must be taken that the spectrum analyser used can accept a signal input of
33dBm. If not, an appropriate attenuator must be used.

I, Q ch Offsets

Spectrum analyser setup:
Centre frequency = 902.4MHz
RBW = 10kHz
VBW = 10kHz
span = 1MHz
sweep time = 2sec

1. Set the Channel box to channel62 at power level 5, nominal burst modulated with all 1’s, as shown below:

Figure 6.23: Channel box setup

2. On the spectrum analyser, measure the image leak ratio.
Image leak ratio is the measured ratio of peak power and the power at 135kHz below peak frequency.
Example:

Peak power= 33dB
Power at 135kHz below peak power= -9dBm
Image leakage ratio = 33dBm - (-9dBm)= 42dBm

6.6.5. Battery Calibration

Preliminaries

There are three procedures to calibrating the battery, voltage, temperature and charging calibration. A Battery Calibration
Voltage Control Unit (BCVCU) is used to provide the necessary voltage levels for these checks. The BCVCU replaces the two
regulated power supplies and 82 Ohm resistor required to caibrate previous mobile products.

1. Connect the telephone, test battery, BCVCU and Interface Box as shown in the diagram below.

BCVCU

TEST BATTERY

Figure 6.26: Battery calibration test conections

2. Set the Interface box to POWER ON, IGN and EXT PWR OFF.

Voltage Calibration

1. Enter Test-Set mode in Service Channel Box.

4. Set VBAT to 3.0V by selecting 3.0V on the BCVCU.

5. On the PC, press ‘Y’ and then ENTER.

6. Check the ADIN1 reading again - this is the BAT VOLT LOW value. If the reading is outside the range 390-490, there is
a fault and further investigation is required. Otherwise, record this value for use later.

7. Press ‘N’ in the {repeat yes/ no box}, then press ENTER.

8. Press F6. Scroll down to, and select TRIM OTHER.

9. Scroll down to, and select BAT VOLT HIGH. Enter the value recorded in step3.

TEST AND MEASUREMENT

Figure 6.36: Charging calibration 4

Current Charging ADC Calibration

It is important to monitor the current when charging the Li-ion battery, both to protect against over-current and to determine
when charging is complete. The telephone uses the VCC3 and MADC (ICHG) connections of OMEGA to measure charging
current as an amplified voltage across a sense resistor.

NOTE: This calibration procedure MUST be carried out once Charging Voltage calibration has been completed.

1. Press F4 and select VIEW ADC LINES. Read ADIN5 (CRG CURRENT) and record this value.

Figure 6.37: ADC Calibration

2. If this value is outside the range 101-251, then there is a fault and further investigation is required. Otherwise, calculate
the difference between the recorded value and the theoretical value of 161. Record this value for use later.

3. Press F6 and select TRIM OTHER. Select COMP OFFSET and enter the value recorded in step2.

4. Press F9. Wait for the prompt “Saving EV Trim data” to disappear, turn OFF the power supplies and disconnect the
telephone.
