SERVICING CONCERNS

1. When requested, back up user’s handset data using SPST (SHARP Program 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 according to the following flowchart.

Repairs 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 RF performance check with SPST.

All completed.

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 main and external display panels.

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 deterioration.

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 st ati c electr icity o f integr at ed circui ts and ot her circui ts. Wear sta tic el ectrici ty preven tion ba nds whi le ser vicing.

This section describes how to rewrite MOT files.

1) Downloader for Emergency

1. Click “Downloader for Emergency“.

Note:

• Handset must be turned off before making any connections. Press and hold the Power key to turn off handset. Do not turn off in other ways. Malfunction may occur and the MOT file rewrite operation may fail.

• Make sure the handset battery is sufficiently charged. If the battery is low, the MOT file rewrite operation may fail. Charge the battery before the operation.

• Disco nnect the AC charger from a cable for upgrading. When rewriting MOT files using the upgrading tool, do not connect the AC charger to the cable. If you connect the cable connected to the AC charger to handset, charging starts and the MOT file rewrite operation is interrupted.

• All SET POWER SW on Communication Box must be turned off. If handset is connected with SET POWER SW turned on, charging starts and the MOT file rewrite operation is interrupted.

• Make sure handset and Communication Box Cable 1 are

connected via the conversion connector.

(When using Communication Box, the only handset connected to Cable 1 can be operated on the PC.)

2. The upgrading tool is activated.

Note: Disable the power saving mode before rewriting MOT files.

You can shorten time for the MOT rewrite operation by selecting a smaller value for Wait Time. Example: Time to rewrite two MOT files at a time. At the default setting (3 seconds), rewrite time is approximately 40 minutes. If the value is set to 1, the rewrite time will be reduced to approximately 30 minutes. If an error occurs at 1, increase the value. The error screen will appear on handsets No. 2 to No.10. If this screen appears, increase Wait Time and retry.

When using Communication Box, set Wait Time. Check the Communication Box check box to adjust Wait Time (default: 3 seconds). The time to delete t he program da ta varie s betwee n han dsets. Handsets wait for the set Wait Time until the whole process is completed. If an error occurs, increase the value.

When the File System Initialize check box is checked, a confirmation message appears.

Click the [OK] button.

Note: When you check File System Initialize check box and click the

[OK] button, handset status returns to the default. In this case, user data is initialized after the MOT file rewrite operation. Uncheck the check box to avoid this.

[Notes for the Wait Time setting]

When the set value is smaller than the default (3), the message on the left appears alerting you a possible error.

Click the [OK] button to proceed, and click the [Cancel] button to change the value.

Canceling the ongoing rewr ite operation:

Click the [QU I T] button. To rewrite MOT files later, remove and install the battery first.

[Notes for the use of a cable for upgrading]

1. Disconnect the AC charger from the cable. Otherwise charging starts and the MOT file rewrite operation is interrupted.

2. Make sure the handset battery is sufficiently charged. If the battery is low, the rewrite operation may fail. Charge the battery before the operation.

3. If the ongoing rewrite operation is canceled, or interrupted by an error, remove and reinstall the battery and retry.

[Notes for the use of the Communication Box]

1. When "Press Po wer Button!" appears, t urn on Communication Box SW from No.10 down to No.1. If the communication BoxSW No.1 is first turned on, the rewrite on communication BoxSW No. 2 to No. 10 operation will fai l.

2. The time to delete the program data varies between handsets. If the process fails at the default Wait Time (3 seconds), increase the value. Consequently, this will increase the time to complete the rewrite operation.

5) Checking the value of SUM

When the rewrite operation is completed, a confirmation message appears with SUM.

Make sure SUM is the same between the PC and handset.

The same SUM means that the rewrite operation is completed properly. If the value is different, try again to ensure completion of the operation.

If the MOT file rewrite operation fails, an error message appears on handset.

The screen shot on the left shows an error in erasing Flash data.

[ADR] and [STR] appear only when an error occurs in the FLASHrelated operation. Start over the MOT file rewrite operation. <When other error messages appear> Find the message in 4-4-4. 2)Error messages for Loading loader, and follow the instructions.

[Procedure]

1. Select a channel and band. [see 4-6-3.1)]

2. Select RX Gain using RX Gain Setting bar.

3. Choose Sniff ON or OFF.

4. Click "RX ON" to start receiving burst signals.

5. From GSM tester, send burst signals in the specified channel.

(You can check each part in this state.)

6. Click "RX OFF" to end receiving burst signals. In this test, the reception timing cannot be synchronized with burst

signals from Signal Generator or GSM tester. The standard RX Gain Setting is:

(Input power at the aerial conne ctor of the han dset) + (RX G ain) = -16 dBm Excessive Input power or RX Ga in may cause damage to the hand set.

4) RSSI Measure
