The black 3-pin port is provided for programming of the unit. The unit can also be programmed using the
Bitwriter. When using the Bitwriter, it is possible to configure any and all of the programmable functions as well
as lock the Transmitter/Receiver and System Features Learn Routines so that unauthorized users cannot change
the configuration or program transmitters to the unit.
When the learn routines have previously been programmed using the Bitwriter, they may have been locked.
Before proceeding with reprogramming the learn routines, they must be unlocked with the Bitwriter - this
cannot be done manually with the Valet switch.
