LINEAR SMDRG LINEAR 1 CHANNEL RECEIVER WITH
MegaCode receivers and transmitters do not contain a typical "coding switch". Each transmitter is pre-set at the factory to a unique code. The receiver is programmed by sending a signal to it from the transmitter(s) that are going to be used with it. This stores the transmitters code into the receiver's memory. The receiver will retain its memory even without power. The receiver will activate only from these "memorized" transmitters. Each MegaCode receiver can remember a maximum of 10 transmitters. Receivers are normally powered with 24 volts AC/DC from the gate operator. The SMDRG has a built-in type "F" connector and is supplied with a 9 inch whip antenna.
