NOTE FOR REPLACEMENT OF THE EEPROM
The ID cord is written in the EEPROM.
When replacing the EEPROM, U6 on the B ASE MAIN board and
U4 on HAND MAIN board should be replaced together as a pair.
(Part No. X-3381-018-1)
PRIOR CHECK FOR SERVICING
This set can rewrite the ID number of handset to the ID number of
base unit in the test mode even their serial numbers are different.
You can find which is wrong, handset or base unit with this function.
Note: A normal set is needed for this test.
Define A as the normal set and B as the faulty set.
Disconnect their power.
Procedure:
1. Press the [PGM] key.
2. Select the “DIAL MODE” menu by pressing v or V keys.
3. Press the key sequence [SELECT], [2], [1], [0], [4].
4. When enter the test mode, happ y tone is emitted, and the LCD
displays as shown below.
ABOUT U7 ON THE BASE MAIN BOARD
U7 (Part No. 6-800-854-01) on the BASE MAIN board which has
board shape as shown below , is dif ferent from regular ICs in shape.
5. Press the key sequence [#], [2], [1], [1], [0] just after power
ON.
6. When enter the test mode, the [SPEAKERPHONE] LED and
[INTERCOM] LED light up, and happy tone is emitted.
7. Disconnect the po wer of the handset B, then connect the power
again.
8. Disconnect the power of the base unit A, then connect the po wer
again.
9. Cradle the handset B on the base unit A to charge the battery
of handset B for about 1 minute.
10. Press the [TALK] key of the handset B and join the base unit
A.
11. When joining is successful, the handset B is normal. But when
it fails, charge the battery of the handset B again.
12. Next, repeat the step 1 to step 9 with the handset A and base
unit B
13. When joining is successful with handset A and base unit B,
base unit B is normal and handset B is faulty.
