Operation

The status LED on the Fiber-optic Transmitter will indicate its state. You
must have this working before you install the cable and Fiber-optic Receiver.
When the status LED is "OFF", the ignition should be off. Check that when
this LED is off the LED connected to the Fiber-optic Receiver is also off.
When the status LED on the Fiber-optic Transmitter is "ON", the LED
connected to the Fiber-optic Receiver should also be on.

Testing the installation

The Ignition Cutoff installation is tested by observing the LEDs on both the
Fiber-optic Transmitter and Fiber-optic Receiver in the ON and OFF modes.
They should both be ON and both be OFF with the given transmitter
command.
If the switch On/Off position is not the direction you would
prefer, use the channel reverse to change this.
The channel controlling the Ignition Cutoff must have its failsafe set if the
radio is any type other than FM (PPM). To test this, turn the Ignition Cutoff
on using the switch on the transmitter and then turn the transmitter off. The
Ignition Cutoff should turn off. If not, check your failsafe settings for this
channel.
