1.21 Watchman
The radar "wakes up" at specified time
intervals (5, 10, or 20 minutes) and operates
for 10 scans, the start of which is announced
by releasing the audio alarm. If change is
found in the guard zone from the previous 10
scans, the audio alarm sounds and the radar
resumes normal operation, canceling the
watchman mode. If no change is found, the
radar goes into stand-by, for the specified
time interval. This feature is useful for
periodic watch of the guard zone.

1.22 Suppressing Long-range
Rain Clutter
In adverse weather, clouds, rain or snow
produce spray-like spurious echoes which
impair target detection over a long distance.
These echoes can be suppressed by turning
on the FTC (Fast Time Constant). FTC works
by splitting up these unwanted echoes into a
speckled pattern, making recognition of solid
targets easier.
