REGISTRATION PROCEDURE
1. NEW CODE REGISTRATION
NOTICE:
If pressing the switch of the original transmitter to
register the code, the system might operate.
When registering the transmitter codes such as for
garage or gate, check that there is nobody around
those places.
(a) Press the switch of the item to be registered for 20 se-
conds.
HINT:
When transferring to registration mode, garage door indicator
(green) blinks in 1 Hz cycle.
(b) Bring the original transmitter to within 1±inch area around
the garage door opener and press the switch (code trans-
mitting).
HINT:
When code registration is complete correctly, the garage door
indicator (green) blinks in 5.6 Hz cycle.

If a code can not be registered, observe the following condi-
tions.
HINT:
If the battery of original transmitter is consumed.
Press the switch of the transmitter repeatedly in registra-
tion mode, as some transmitters stop transmitting for 1 to
2 seconds.

2. CODE DELETION
(a) Press the switches at both ends of the garage door open-
er simultaneously for 20 seconds.
HINT:
When transferring to deletion mode, garage door indicator
(green) blinks in 6 Hz cycle.
(b) When releasing the switch within 10 seconds after trans-
ferring to deletion mode, all the registered codes will be
erased.
HINT:
Press the switch until 6 Hz cycle blinking stops, so that the de-
fault code for check is set.
