WARNING
Receiver & Remote Control Programming
NOTICE: To comply with FCC rules, adjustment or modification of this
receiver and/or transmitter are prohibited, except for changing the code
setting or replacing the transmitter battery. THERE ARE NO OTHER
USER SERVICEABLE PARTS.
Your garage door opener receiver and remote
control transmitter have been set at the factory to a
matching code. The door will activate when the
remote control push button is pressed.
Your "Smart" garage door opener will operate with:
• up to four "Smart" remote control transmitters
(with green indicator lights),
• a Keyless Entry System, and
• code switch remote controls with red indicator
lights.
Below are instructions for programming your opener
to match any additional remotes you may purchase.
See available accessories on page 34.
To Add a Single Function Remote Control
1. Press and hold the remote push button (Figure 1).
2. Then press and release the "Smart" button on the
right side panel of the opener, Figure 2. The
opener lights will
flash once.
3. Release the remote push button.
Now the opener will operate when the remote
control push button is pressed.
If you release the remote control push button
before the opener lights flash, the opener will
not accept the code.
To Change the Selected Push Button
on the Same Remote
If you decide to use a different remote control button
than originally programmed into the opener, you
need to erase
all the learned codes and reprogram
each remote used to operate the garage door
opener.
To Erase all Remote Control Codes:
• Press and hold the "Smart" button on the opener
panel until the indicator light turns off (about 6
seconds).
All the codes the opener has learned
will be erased.
• To reprogram, repeat Steps 1 - 3 for each remote
control in use.
Code programming instructions are also located
on the opener panel.
