Transmitter Synchronization

Transmitters will need to be resynchronized any time the batteries are removed / replaced or the transmitter is pressed greater than 250 times outside the range of the receiver.

Resynchronization does not send the mathematical formula to the receiver, it simply verifies the previously programmed mathematical formula in the transmitter.
Resynchronization only works if the transmitter is already programmed. To resynchronize the transmitter:

1. Depress the "LOCK" and "UNLOCK" button on the transmitter simultaneously for 5 seconds.
2. The receiver will acknowledge resynchronization by cycling unlock and then lock.
