Associated model number: 64LM

The multi-function mini transmitter has three buttons. The large top button is recommended for use with a garage door opener and/or light control product. The other push buttons can be used to operate another garage door opener and/or light control product. Instructions for programming light controls are included with those accessories.

To match the code switches in the new and original transmitters:

Locate the code switches in the multi-function mini transmitter by turning the transmitter over and removing the case screw and removing the back of the case. Be careful to avoid moving the circuit board components.

Place the new transmitter and the original transmitter side by side, and set the switches in both transmitters to matching positions (+,0,-). Use a pen or screwdriver to slide the code switches.

NOTE: Code switch #1 in the multi-function mini transmitter is dormant, when used with a single-function transmitter. Set code switch #1, in the single function transmitter, to match the push button selected on the multi-function mini transmitter.

Programming the opener (if your unit has a "Learn" button):

  1. Press and release the "learn " button. This can be found where you see the antenna wire hanging from the motor head (you may have to take the lens cover off). If antenna wire is not hanging from motor head then you have an external receiver which is a black box approx. 6" x 2" mounted somewhere in the garage with a antenna wire hanging from it (pop off cover to find Learn Code Button). The learn indicator light will glow steadily for 30 seconds.
  2. Within the 30 second window, press and hold the button on the hand-held remote.
  3. The unit will either activate or the opener light bulb will blink signifying it has learned the code.

If your unit has code switches:

  1. Using a step ladder climb up to the back of your motor unit. Check the code switch settings on the back of the motor unit. Your code block with dip switches can be found where you see the antenna wire hanging from the motor head (you may have to take the lens cover off). If antenna wire is not hanging from motor head then you have an external receiver which is a black box approx. 6" x 2" mounted somewhere in the garage with a antenna wire hanging from it (pop off cover to find code block with dip switches).
  2. Use a pen or screw driver to set the code switches on the back of the transmitter to match the code switches on the back of the motor unit.
  3. Once the code switches have been set push the transmitter button to activate your unit.

Replacing the transmitter battery:

  1. The 12Volt battery should provide power for up to 1 year. To replace the battery remove the case screw and the cover.
  2. Dispose of old batteries properly.
  3. Locate the battery by sliding the battery compartment cover.
  4. Dispose of old batteries properly.
