one (1) time. You are now in the programming mode.

alarm siren responds with a confirming chirp. The first transmitter is

Within five (5) seconds, press the ON/OFF button on the second 
transmitter until the alarm siren responds with a confirming chirp. 
The second transmitter is now programmed. NOTE: If the RF-502

will automatically close the programming mode and resume normal 
alarm functions. If this happens, it will be necessary to repeat steps 
1 through 6 and re-program all transmitters. If three or four 
transmitters are programmed, continue pressing the ON/OFF 
button of the third and/or fourth transmitters. 
6. The RF-502 can learn up to four remote transmitter codes. If later
optional third and forth transmitters are to be programmed, follow 
sequence 1 through 6 and re-program all existing transmitters.
