press Enter. The door should move. If the temporary PIN was
set to a certain number of openings, remember that the test

programmed to keypads working on a Chamberlain or

programmed to an external receiver.
The temporary password will continue to CLOSE the door even
after the time has expired. To eliminate this, program a new
temporary password into the keypad.
