Children operating or playing with a garage door opener
can injure themselves or others. The garage door could
close and cause serious injury or death. Do not allow
children to operate the wall push button(s) or remote
control(s).
A moving garage door could injure or kill someone under
it. Activate the opener only when you can see the door
clearly, it is free of obstructions, and is properly adjusted.

The push buttons on the Four-Function remote controls can
activate garage door openers, entryways and/or light controls.
(Instructions for programming light products are included with
those accessories.)
In general, code switch remote controls are used when
several persons are operating the same device. Code
switches must be set to matching positions in all remote
controls used to operate the same receiver. Follow the
instructions for Figures 1 and 2. Use the "ribbed" push
button exclusively for code switch application.
Access the code switches in the 84LM, four-function remote(s)
as follows:
• Remove the battery compartment cover as shown in Figure 1.
• Remove the case screw on the housing bottom.
• Hold the remote control as indicated and pull to separate the
housing. Set aside the case top (with push buttons).
• Place remote circuit boards side by side. Make sure you set
code switches 1 through 9 in all remotes to matching positions
(see Figure 2). Use a pen or a screwdriver to move the
switches to (+), (-) or (0).
• Reassemble case top and bottom by snapping them together.
• Replace the case screw and battery compartment cover.

Program Receiver to Match Remote Control Code:
Each receiver must be programmed to accept the code of the
remote push buton that will be used to operate the device.
When several remotes will operate the same device, it is only
necessary to use the "ribbed" push button of one remote to
program the receiver.
Select a remote control push button to operate the receiver.
• Press and HOLD the selected push button, Figure 1.
• Then press the "SMART" button on the receiver panel (see
Figure 3). The green indicator light will FLASH once. Release
the remote control push button.
Now the device will operate with the selected remote push button.
NOTE: If the remote push button is not held down until the
indicator light flashes, the receiver has not accepted the code.
If the "SMART" button is pressed and held until the
adjacent indicator light turns off (about 6 seconds) ALL the
codes the receiver has learned will be erased.
