LiftMaster 387LM Universal Wireless Keyless Entry Garage Door Keypad
Read instructions thoroughly BEFORE beginning. Start with the garage door closed. Determine garage door opener type-Smart/Learn button or DIP Switch. The Smart/Learn button or DIP Switches are located on the motor unit or external receiver. Refer to the owner’s manual if necessary. LiftMaster products are intended to be used only with garage door openers manufactured after 1993 that utilize photo-eyes safety sensors. These are always located on or near the bottom of the door track. If your garage door does not have the sensors attached and working, the opener is not compliant with current federal safety regulations and should be replaced.
