SERVICING NOTES

SPP-N1025/N1026

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.

NOTE FOR REPAIRING AND REPLACEMENT OF THE NEW TYPE BO ARD

When a new type board is damaged or out of order, do not repair that board, but replace with an former type board (BASE MAIN board : Part No. A-3062-834-A, HAND MAIN board : Part No. A-3062-832-A (N1025)/A-3062-877-A(N1026)). In this case, remove the EEPROM (BASE MAIN board : Ref No. U6, HAND MAIN board : Ref No. U4) from the new type board and install it on the former type board as a replacement.

Security Code Synchronization

The following procedures should be followed if the security codes of both unit do not match to each other.

1. Put the handset into manual test mode, making sure the channel is set at 14 (default) out of 0 to 29.

2. Press the [*] key to start data transmission under which the

SC_SYNC command is sent continuously.

3. Put the base unit into manual test mode.

4. Before the base unit enters the manual test mode, it waits one

second for receiving SC_SYNC command from the handset. If the command is received in the period, its security code will be saved into EEPROM and then flash the [LINE] LED for indication.

5-3. NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS

Note on Printed Wiring Board:

• X : parts extracted from the component side.

• Y : parts extracted from the conductor side.

•

: Through hole.

• : Pattern from the side which enables seeing.

• : Carbon pattern. (The other layers' patterns are not indicated.)

Caution: Pattern face side: Parts on the pattern face side seen from (Conductor Side) the pattern face are indicated. Parts face side: Parts on the parts face side seen from (Component Side) the parts face are indicated.

Note on Schematic Diagram:

• All capacitors are in µF unless otherwise noted. pF: µµF 50 WV or less are not indicated except for electrolytics and tantalums.

• All resistors are in Ω and 1/ specified.

• % : indicates tolerance.

• C : panel designation.

• A : B+ Line.

• Power voltages are dc 9 V and fed with regulated dc pow er supply from external power voltage jack (J3) on the BASE MAIN board, dc 12 V and fed with regulated dc power supply from modular jack (J7) on the BASE MAIN board with 100 Ω in series, and dc 3.6 V and f ed with regulated dc power supply from battery terminal (J5) on the HAND MAIN board.

• Voltages and wa vef orms are dc with respect to ground in test mode.

• Voltages are taken with a V OM (Input impedance 10 MΩ). Voltage variations may be noted due to normal production tolerances.

• Waveforms are taken with a oscilloscope. Voltage variations may be noted due to normal production tolerances.

• Circled numbers refer to waveforms.

• Signal path.
