If you already have a transmitter that operates
your gate and are simply adding an additional
transmitter, set the DIP switches in the new
transmitter to match the DIP switches in
your original transmitter, reassemble the
transmitters and you are done.
If you are replacing a lost transmitter and you know or have your original transmitter’s DIP switch
setting written down, set the new transmitter DIP switches to that setting and it is ready to activate
your gate opener.
If you don’t know the DIP switch setting from your original transmitter,
you will need to select a new setting.
Personalize your Transmitter Setting
There are nine (9) DIP switches, each of which can be placed in
three different positions (+,0,-). DO NOT set all switches in the same
position, such as all +, all -, or all zeros.
Program New Transmitter Setting to Gate Opener’s Memory
Some gate openers are programmed with a LEARN REMOTE or
LEARN TRANSMITTER button and some with the ON/OFF switch.
Refer to your Gate Opener’s Installation Manual for instructions on
how to program the transmitter to your gate opener.
NOTE: If the red light on the transmitter is dim or flickers when the
transmitter button is pushed, the transmitter battery may be weak.
Replace when necessary with a A23S 12 Volt battery.
