BEFORE YOU START Read instructions thoroughly BEFORE beginning. If you are using this product with residential door openers, this product must be used only with door openers manufactured starting January 1, 1993, that use photoelectric sensors located near the bottom of the door track.

HOW TO USE THE WIRELESS KEYLESS ENTRY
The garage door opener activates when you press the personal identification number (PIN) and ENTER button. The keypad will blink for 15 seconds.

The wireless keyless entry will transmit only the last four digits that were pressed before the ENTER button.
