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)

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. While pressing the [HANDSET LOCATOR] key, turn the
power on, then releasing and pressing it again within 2
seconds.
2. When enter the test mode, the [LINE] LED blinks slowly.
2. Default Settings
• Channel set to 14. (out of 0 to 29)
• Combo set to active mode.
