81LM Garage Remote

[FredLooban]

Guys I need your help!

I bought this 375LM for our garage, it's a replacement for 81LM.

And I don't know how to make it work.

It keeps saying there are switches on control of the garage door but there is none.

I have the manual but it still keeps saying I have to open the control on the motor but I don't see any switches.

Thanks!

Fred

You need to pair up the little tabs in your remote(usually found where the battery goes in) to the same tab settings on your drive motor. Usually they are located on the back of the unit. In this case simply find the tabs(switches) on your old remote and the tabs on your new remote and make sure the ones on the new remote are set the same as old one.
In your case from what I just researched this may help you better...

Did you look at the door opener it's self?

There should be ether a smart button or a row of dip switches as shown in the manual on page #2, they may be under a cover.

If there is only the one button then you press it and the learn LED should come on, you then press and hold the button on the remote till the lights on the opener blink, the remote then should be programmed.

If there is a row of dip switches you then open the cover on the remote and match the pattern from the opener.

If you don't have a manual for ether, here are two links to both.
