RADAR SET UP
The RADAR ADJUST menu contains settings which should be
done at installation or after any repairs to optimize the performance of
the radar system. It is recommended that the radar be run in transmit
mode for at least 10 minutes before adjusting the Preset Tuning in order
to stabilize the transmitter circuit first. It is also recommended to adjust
the Preset Tuning first as the other adjustments will be easier to do after
that. If Preset tuning is not correct, then the Auto Tune may not work
or may not work correctly and receiving targets will be decreased or
eliminated. If Preset STC is up too high the loss of closer in targets will
occur. These are the 2 most important adjustments for viewing target
echos. Bearing alignment and Range (Timing) adjustments are
important for correct picture orientation and safety.
