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. The blanking occurs on the main radar

PPI and on the radar overlay on a chart.

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.

Note: Sector blanking should be applied very carefully to avoid reducing the radar’s

usefulness in identifying valid and potentially dangerous targets.

Main radar PPI Radar overlay on a chart

Adjust open array park angle

(Halo Radar only)

The park angle is the final resting position of the antenna relative to the heading line of the

radar when the radar is set to standby. The antenna will stop rotating at the desired offset.

Adjust local interference reject

Interference from some onboard sources can interfere with the Broadband radar. One

symptom of this could be a large target on the screen that remains in the same relative

bearing even if the vessel changes direction.

Choose from Local interference rejection LOW, MED or HIGH. Default is LOW.

Halo light

(Halo radar only)

Controls the levels of the Halo Radar pedestal blue accent lighting. The accent lighting can

only be adjusted when the radar is in standby mode.

Note: The blue accent pedestal lighting might not be approved for use in your boating

location. Check your local boating regulations before turning the blue accent lights ON.

Restore radar to factory defaults

This option can be used to revert all user adjustments.

Echosounder settings

A compatible echosounder module (or another unit which has built-in sonar) shared over

the Ethernet network is required to view echosounder images on the unit.

Network echosounder mode

The network echosounder mode setting selects whether only one or multiple echosounder

sources can be selected at the same time.
