Compatibility

To determine compatibility with your garage door opener, please look for a combination of the following features:

  • Gray external radio receiver box present on back of garage door opener powerhead (motor mounted to ceiling of garage) - to see what the receiver looks like visit the page for the Multi Code receiver
  • Antennae wire coming out of the receiver
  • Remote controls you currently use say Multi Code on them and look like the model pictured or like the MC-3089
  • If you do not have any remote controls, usually the fact that you can see the radio receiver box on the back of your garage door opener powerhead is enough to be sure this remote control will work for you.

If you do not have any remote controls, usually the fact that you can see the radio receiver box on the back of your garage door opener powerhead is enough to be sure this remote control will work for you.

If you cannot see the radio receiver or are not sure it is the same one we have pictured, we recommend that you install a new radio receiver/transmitter to make this remote compatible with your motor - Multi Code 1090 receiver

Instructions
Programming Instructions You may set your transmitter to any code you desire but be sure that the code you set matches the code that has been set on your radio receiver. The digital code is determined by the positions of the 10 small switches numbered 1 through 10 located in the receiver and transmitter. Any combination of ON (CLOSED) or OFF(OPEN) positions can be selected by using a small screwdriver or ball point pen.(NOTE: The switches are in the ON position when the side next to the number is pressed in.) In setting your own personal code we strongly urge that several coding schemes be avoided: ALL ON; ALL OFF; 2, 4, 6, 8, 10 ON; 1, 3, 5, 7, 9 ON. These positions are similar to our or other manufacturer test positions, or are frequently used. Once the code has been set, check the operation and replace the hatches.
