SERVICING CONCERNS
1. When requested, back up user’s handset data using SPST (SHA P Programme Support Tool). Otherwise, before servicing, warn the user that
data in the memory may be lost during repairs.
2. Upgrade the firmware to the latest version using SPST before returning the handset to the customer.
3. After repairs, inspect the handset (phone) according to the following flowchart.
4. When storing or transporting a PWB, put it into a conductive bag or wrap it in aluminum foil. (C-MOS IC may be damaged by electrostatic
charges.)
5. Do not leave fingerprints, etc. on ornamental parts including a cabinet, especially clear windows for main and sub displays. Wear fingerstalls to
avoid this.
Also, ensure not to leave fingerprints on the surface of display panel.
6. To prevent oxidation which causes connection problems, do not touch any terminals on the electric board, microphone, vibrator, earpiece and
speaker.
When handling these parts, wear fingerstalls. Should you touch these parts, clean them with a soft dry cloth.
Always wear fingerstalls when handling a shield case on the electric board. Otherwise oxidation may occur causing handset performance deterio-
ration.
7. The FPC is a precision device. Handle it carefully to prevent any damages.
8. Do not expose the moisture sensor to liquids.
If the sheet gets wet, red ink runs. In this case, replace the sheet with a new one.
Be careful about your perspiration.
9. Before you disassemble or reassemble handset, make sure to remove the Li-Ion battery.
10.Be sufficiently careful with static electricity of integrated circuits and other circuits. Wear static electricity prevention bands whilst servicing.
epairs are completed.
(Fixed parts have been checked for proper operation.)
Check IMEI NO./Operator code (Destination)/
Firmware version by Identity function of SPST.
Inspect each device using performance check
adjustment function of SPST.
Carry out F performance check with SPST.
All completed.

Employing lead-free solder
Lead-free solder is used for this model.
This is indicated by the “LF” symbol printed on the PWB and in the service manual.
The suffix letter indicates the alloy type of the solder.
Example:
Indicates lead-free solder of tin, silver and copper.
Using lead-free solder
When repairing a PWB with the “LF” symbol, only lead-free solder should be used. (Using normal tin/lead alloy solder may
result in cold soldered joints and damage to printed patterns.)
As the melting point of lead-free solder is approximately 40ºC higher than tin/lead alloy solder, it is recommended that a
dedicated bit is used, and that the iron temperature is adjusted accordingly.
Soldering
As the melting point of lead-free solder (Sn-Ag-Cu) is higher and has poorer wettability (flow), to prevent damage to the land
of the PWB, extreme care should be taken not to leave the bit in contact with the PWB for an extended period of time.
Remove the bit as soon as a good flow is achieved.
The high content of tin in lead free solder will cause premature corrosion of the bit.
To reduce wear on the bit, reduce the temperature or turn off the iron when it is not required.
Leaving different types of solder on the bit will cause contamination of the different alloys, which will alter their
characteristics, making good soldering more difficult.
It will be necessary to clean and replace bits more often when using lead-free solder. To reduce bit wear, care should be
taken to clean the bit thoroughly after each use.
