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.

WARNING

ADVERTENCIA

WARNING

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.
