Replacing a Lost Programming Code
The AC-Q74 must be in Normal mode; otherwise, this does
not work. Make sure that the Mode LED is green before
proceeding.

2.
Press the REX button on the Power Supply Unit (PC-25T).

Release the REX button.

You now have 15 seconds to program a new Programming code
into the Access Control unit using the initial default code 1234,
before the controller reverts to the existing code.
