REPLACE DOOR CONTROL RECEIVER AND TRANS-
MITTER
NOTICE:
When replacing the door control receiver and transmitter,
registration of recongnition code is necessary because
they are provided as single components.
(a)
Select which operation mode should be performed from
the following modes.
Add mode
Rewrite mode
Prohibition mode
Confirmation mode
HINT:
The add mode is used to retain codes already registered
while you register new recongnition codes. This mode is
used when adding a transmitter. However, if the number
of registered codes exceeds 4 codes, previously regis-
tered codes are correspondingly erased in order, starting
from the first registered code.
The rewrite mode is used to erase all previously regis-
tered codes and register only new recognition codes.
The prohibition mode is used to erase all registered codes
and cancels the wireless door lock function. Use this
mode when the transmitter is lost.
The confirmation mode is for confirming how many re-
congnition codes are already registered before you regis-
ter additional recognition codes.
(b)
Follow the chart on the following pages to register the
transmitter recongnition code at the wireless door lock
conrol receiver.
HINT:
When procedure is out of the specified, the operation re-
turns to normal operation.
Maximum 4 recognition codes can be registered.
