Operation of Guard Zones
When a target is within a fan-shaped guard zone, an alarm will sound and a mark  will appear
on the target.  The tracking mode is entered after about 1 min.
In creating a guard zone, a circular guard ring may be created if the start and end points of the
guard zone are set to the same point by omitting step 5 above.
The guard zone is displayed only during radar transmission, but not appear during the standby
operation.
Automatic Operation
When pressing  , the set guard zone 1 or 2 will appear.  If there is a target within
the guard zone, the guard zone operates automatically.  When the target goes out 
of the zone, it is tracked.  (The default is set for Guard Zone 1 only)
