Launch Amplifier

There are two variable controls, Lift and Gain, situated close to the BNC connector J1. These are
pre-adjusted for a cable distance of 500m, and are adjustable to compensate for video detail or
signal losses if and when longer or shorter cable lengths are used to connect the monitor to the
receiver.
ATTENTION: Ensure that the cable is terminated at the monitor end ONLY
Depending on the jumper selection of SW3 and SW4, only one of the four auxiliary functions can
be selected at any one time.
