Model387LM

11/3/2012 12:00:00 AM I purchased this product to replace Model66LM which we have had for approximately 20 years. I still have the installations instructions for this model. They are simply and straight to the point to understand. The installation instructions for the new Lift-Master Model 387LM are NOT very clean for the average person to understand. The instructions make reference to :your first DIP switch must be set to the "-" position on your remote and the opener." However they do not show you how to set these numbers on the opener! One is left wondering. A simple diagram first of all to indicate where these numbers are located in the opener would be most benefical and how they are to be accessed! The instructions leave one wondering. Does that mean that I have to open up the opener? The instructions are NOT user friendly!. It appears that I may have to get a service tech to install the Wireless Keyless Entry. What a shame?

Great Tech Support

6/24/2013 12:00:00 AM I have an old 1200 series Liftmaster garage door opener and was not sure if this keypad was compatible. I contacted tech support and was told that it was. The support person explained how to program it and emailed the instructions to me. When it came to installing it, it was a breeze! There are no dip switches to set on the keypad. The instructions show that some garage door openers have dip switches that may need to be adjusted. Mine just had a green button on it, so I was able to skip that step. The keypad looks great and works flawlessly.
