Sine Systems RFC-1/B - Page 22

The easiest way to set this up as a "loss of audio" alarm is to turn the telemetry pot wide open
(keep turning the calibration control clockwise until you hear a soft clicking sound; the
override clutch). Then set the upper limit for this channel to 2040 and the lower limit to
around 0150. With audio present, the reading will be "Status: On" almost all the time
meaning that the telemetry is pegged against the upper end of the scale (2040). During long
pauses the reading will change to numerical values. When the value drops to 0150 or below,
the RFC- 1 will catch it on the next scan.
