Sector blanking
Radar installed in close proximity to a mast or structure could cause
unwanted reflections or interference to appear on the radar image.
Use the sector blanking feature to stop the radar from transmitting
on up to four sectors in the image.
Ú Note:
Sectors are setup relative to the heading line of the radar.
The bearing of the sector is measured from the center line of
the sector.
Ú Note:
Sector blanking should be applied very carefully to avoid
reducing the radar's usefulness in identifying valid and
potentially dangerous targets.

the heading line of the radar when the radar is set to standby. The
antenna will stop rotating at the desired offset.
Tune
The automatic tuning will work well in most installations. The
manual tuning is used if it is required to adjust the result from an
automatic tuning.
