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. (Parts No. X-3381-019-1)

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.

SECTION 4

TEST MODE

Introduction

The manual test mode can be used for testing the RF and audio sections of the base unit and handset. The manual test mode is also required for the FCC testing in which the phone is tested for interference at the first, middle, and last RF channels.

The following features are provided in manual test mode.

• Able to set operating mode of the combo chip.

• Able to mute or unmute the audio path.

• Able to change the RF channel. (Both RX and TX)

• Able to transmit or receive data packet.

• Able to synchronize the security code.

BASE UNIT

1. Entering the Manual Test Mode

1. While pressing the [HANDSET LOCATOR] key, tur n the power on, then releasing and pressing it again within 2 seconds.

2. When enter the test mode, the [LINE] LED blinks slowly.

• Channel set to 14. (out of 0 to 29)

• Combo set to active mode.

• TX audio path unmuted.

• RX audio path unmuted.

• Off hooked.

• Date transmission disabled.

4. Data Link

Data bits are encoded in manchester format for which bit “0” is represented by 500 µs low and 500 µs high while bit “1” by 500 µs high and 500 µs low. If data transmission is enabled, it will transmit data packet with the following fields continuously. (“0”=500 µs low and “1”=500 µs high)

• 8 bit preamble :0101010101010101

• 8 bit word sync :0110010010010110

• 20 bit security code :Restored from EEPROM

• 4 bit reserved data :01010101

• 8 bit command :0101010101010101

• 8 bit data :0101010101010101 If data transmission is enabled, it will toggle the [LINE] LED every time when a data packet is received. (No security code would be checked)
