Transmitter registration
1. Register:
Remote control transmitter 1
ID codes can be added or re-registered
by connecting the entry box 2.
Registration steps:
Connect the entry box.
Transmit the ID code from the remote
control transmitter to be registered.
NOTE:
The remote control transmitters can be reg-
istered in any sequence, regardless of
whether they are original equipment or
additional transmitters.
At this time, the system enters the regis-
tration mode to register the first code. All
existing ID codes will be deleted from the
EEPROM.
The “SECURITY” indicator light flashes
when the registration of the ID code has
been completed. (If the registration could
not be completed, the “SECURITY” indi-
cator light comes on. Re-transmit the ID
code.)
After confirming that the registration of
the ID code has been completed using
the “SECURITY” indicator light, transmit
the next ID code.
Register the ID codes for up to five
remote control transmitters.
After ID code registration has been com-
pleted, disconnect the entry box to exit
the registration mode.
