2. TEST MODE (SPP-ID300)

Note: See the original service manual for SPP-ID400.

2-1. BASE UNIT

[Setting the Test Mode]

1. Power on with press the [PAGE] key for two seconds.

2. CHARGE LED turns on for one second, and the Test Mode is set. * Press the [PAGE] key for two seconds in test mode, EEPROM (IC102) is been initialize and CHARGE LED turns on.

After this operation, it isn’t able to change Test Mode No. and to change channel.

[Releasing the Test Mode]

To release the Test Mode, perform as follows:

• Turn off the power (disconnect and reconnect the AC adapter plug).

• Set the handset to charge on the base unit (except Test Mode 9).

• Bell in (except Test Mode 8).

[Changing the Test Mode Step]

1. Set the [DIALMODE] switch to the [P] (PULSE) position.

2. Press the [PAGE] key.

3. A step is changed each time the key is pressed, and CHARGE LED turns on for 300 msec.

[Changing the Channel]

1. Set the [DIALMODE] switch to the [T] (TONE) position.

2. Press the [PAGE] key.

3. A channel is changed each time the key is pressed, and CHARGE LED turns on for 300 msec. * Channel will be back to initial channel (6 CH), when Test Mode No. is changed.

When it is Test Mode 12 or 13, DTMF will be changed.
