This prevents anyone from recording and playing back the signal from the transmitter. • Resynchronization may be necessary under the following conditions: - The battery in the transmitter is very weak. - The battery in the transmitter was replaced. - The battery in the vehicle has been in a low or no charge condition for an extended period of time. • In order to resynchronize the transmitter with the RCDLR, perform the following steps: 1.
