Digital code system
The keyfob transmitters communicate to the receiver by digitally coded transmission. Each transmitter is factory pre-programmed with a unique set of security codes from a choice of 260 million different codes and "hops" to a new code after every operation, the receiver unit can learn & memorize the unique security code signature of up to eight individual keyfob transmitters.
Your receiver will be pre-programmed ready for use with any key-fobs purchased with it, but will require programming if any further key-fobs are added.
Programming instructions
1. Remove the receiver cover and locate the small red "Program" button on the printed circuit board and press it briefly, the LED next to the button will flash once to indicate that the receiver has entered into "code learning mode" (the 24v power must be connected)
2. Hold the new keyfob transmitter two metres away from the receiver and press and hold any button until the receiver LED has flashed three times.
3. Repeat steps 1. & 2. above to program a total of up to eight key-fobs.
4. Exit programming mode by repeatedly pressing the red "program" button until the receiver LED illuminates for one second, your key-fob(s) should now operate your receiver.
Clearing the memory - (necessary if a handset has been lost or stolen)
Repeat steps 1 & 2 above eight times (using each of your key-fobs) to "over write" all eight memory slots, this will ensure any previously memorised fobs will be erase
Key-Fob Battery Replacement
Remove the fixing screw on the back cover and open the key-fob casing to reveal a 12 volt car alarm battery type LR-23A
