Receiver Module

Receiver module receives transmitter coded radio signals via an internal antenna. When a signal is sent, it is decoded and compared with preprogrammed radio codes stored in receiver memory. If code is verified, receiver transmits a short 12-volt pulse to central locking relay to lock vehicle or a long 12-volt pulse to unlock vehicle. See Fig 1 .
