Adjusting the sensitivity of the alarm
You can set the sensitivity of the alarm for the
radar guard zones, to define the size of the
target that will trigger the alarm. The size of
target is shown as a percentage.
100% is maximum sensitivity, meaning that
very small targets will trigger the guard zone
alarm. 0% is minimum sensitivity, meaning
that only very large targets will trigger the
alarm.
The same sensitivity setting is applied to
both of the radar guard zones if both are
turned on.
To set the alarm:

Rotation
The current radar rotation is shown in the top
left corner of the radar screen. If COG data or
heading data is not available from a compass,
the radar rotation is automatically set to Head
up.
However, you are strongly recommended
to use a good quality product (such as a
NAVMAN HS02, HS03 or Autopilot) to provide
heading data.
If heading data is available from a compass,
the options are:
• North up works only when COG data or
heading data from a heading sensor is
available. North is always at the top of the
radar screen.
You can easily compare the radar screen to
a chart in North up.
