WARNING

1. INTRODUCTION

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 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 handling procedures are described in Section 6.

Caution

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.

1.1. Purpose of the 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.

1.2. Structure of the Manual

The manual is structured to provide service-engineering personnel with the following information and procedures:

1. General and technical information - provides a basic understanding of the equipment, kits and options, together with detailed information for each of the major component parts.

2. Installation and operating information - provides instructions for unpacking, installing and operating the equipment.

3. Servicing information - provides complete instructions for the testing, disassembly, repair and reassembly of each major component part. Step-by-step troubleshooting information is given to enable the isolation and identification of a malfunction, and thus determine what corrective action should be taken. The test information enables verification of the integrity of the equipment after any remedial action has been carried out.

4. Illustrated parts list - provided to enable the identification of all equipment components, for the ordering of spare / replacement parts.

1.3. Servicing Responsibilities

The procedures described in this manual must be performed by qualified service engineering personnel, at an authorized service centre. The service engineering personnel are responsible for fault diagnosis and repair of all equipment described in this manual.

WARNING

6. DISASSEMBLY / REASSEMBLY INSTRUCTIONS

6.1. General

This section provides disassembly and reassembly procedures for the main components of the telephone. 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 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 handling procedures described are not adhered to.

6.1.1. 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 1.2 MΩ 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 5.2 kΩ AND 1.2 MΩ, SHALL BE USED.

Containers

All containers and storage must be of the conductive type.

8. Carefully insert tweezers into the gap between FPC and Main PCB.

9. Gently lift up the tweezers direction of the arrow and then remove the FPC connector.

10.Remove Main PCB from the lower front cover.

Note:

Take care not to damage the FPC connector when disconnecting the FPC from the Main PCB.

■ Upper Case Assembly and Display Modle removal

1. Set the phone into the "open" position.

2. Using tweezers or a pin gently lift up and remove the three panels.

Note:

The three panels must be replaced with new parts for reassembly.

6.3. Reassembly

IF ANY RF, BLUETOOTH OR BASEBAND SHIELDS ARE REMOVED FROM THE PCB AT ANY TIME, THEY MUST BE REPLACED WITH NEW ITEMS. ONCE REMOVED, THE SHIELDS MUST NOT BE REUSED.

Notes: If the case assemblies have been disassembled and reassembled more than three times, they should

be replaced with new items. Examine all case and cover parts before assembly. If any scratches or defects are found in their finish, they should be replaced with new items.

CAUTION

■ Upper Case reassembly

1. Fit the LCD module onto the upper cover. LCD module

9. Rotate and align the hinge pivot with the open area facing upward and carefuly insert the main area of the lower front cover, taking care to tilt the upper cover assembly without causing damege to the flex circuit during reassembly.

10. Push down until the upper cover assembly is full engaged into the lower front cover.

Caution:

this operation, causing a small tear which can grow with use and render the circuit unusable.

11. Set the phone into the "Open" position.

12. Insert the one push hinge into the lower front cover.

Damage to the flex circuit portion of the upper flex PCB is not repairble. The flex circuit may be easily damaged during
