Works with the 4216 4 channel fob and the 4244 and 4416 fork lift truck transmitters.

Mount the receiver in a plastic control box, away from contactors, timers and inverters. A steel box will block the radio signal. Leave the aerial coiled at the side of the case.

Up to 300 transmitter codes can be programmed using the recessed LEARN button. Holding it for at least 8 seconds erases every code. The full steps are in the manual.
