Handset Initialization

The Theft Alarm Unit (Z163) must be programmed whenever handsets are replaced. The serial communications line is used to activate the "learn mode" of the Theft Alarm Unit (Z163). Then the handset(s) to be initialised must be made to transmit their coded data to the Theft Alarm Unit (Z163).

NOTE: All handset(s) must be programmed during the same learn mode period. It is not possible to simply add a handset to the Theft Alarm Unit (Z163) which has been programmed to other handsets.

When, the "learn mode" of the Theft Alarm Unit (Z163) has been accessed, the handset(s) are programmed using the following procedure:
1. Starting conditions: Theft Alarm disarmed and vehicle mobilised.
2. Press the handset unlock button a minimum of 8 times.
3. If the handset has been correctly programmed, the horn will briefly sound and the hazard lamps will flash once.
4. The next handset, up to a maximum of 4, can now be programmed using the same procedure.

NOTE: It is very important that each handset be programmed separately. If the Theft Alarm Unit (Z163) receives key presses from two handsets, then neither handset will be programmed.

The "learn mode" is terminated using the serial communications line. If the Theft Alarm Unit (Z163) would not accept reprogramming, the original handset(s) will still function.
