VRM/EBL : Shows the variable range marker (VRM) circle
and the electronic bearing line (EBL) to allow you to
measure the distance and bearing from your boat to a
target object (
VRM and EBL , page 52 ).
Guard Zone : Sets a safe zone around your boat and
sounds an alarm when anything enters the zone
(
Enabling a Guard Zone , page 51 ).
Timed Transmit : Helps conserve power by transmitting
radar signals at set intervals.
Radar Setup Menu
From a radar screen, select Options > Radar Setup .
Source : Selects the radar source when more than one
radar is connected to the network.
Chart Display : Shows the chart under the radar image.
When enabled, the Layers menu appears.

caused by interference from another nearby radar
source.
Rotation Spd. : Sets the preferred speed at which the
radar rotates. The High Speed option can be used to
increase the refresh rate. In some situations, the radar
automatically rotates at the normal speed to improve
detection, for example, when a longer range is selected
or when MotionScope or Dual range is used.
Appearance : Sets the color scheme, look-ahead speed,
and navigation appearance.
Installation : Allows you to configure the radar for the
installation, such as setting the front of the boat and
the antenna park position.
Reducing Cross Talk Clutter on the Radar Screen
You can reduce the appearance of clutter caused by
interference from another nearby radar source, when the

Measuring and Setting the Front-of-Boat Offset
The front-of-boat offset compensates for the physical
location of the radar scanner on a boat, if the radar
scanner does not align with the bow-stern axis. The front-
of-boat offset setting configured for use in one radar mode
is applied to every other radar mode and to the radar
overlay.
1 Using a magnetic compass, take an optical bearing of
a stationary target located within viewable range.
2 Measure the target bearing on the radar.
3 If the bearing deviation is more than +/- 1 degree, set
the front-of-boat offset.
4 From a radar screen, select Options > Radar Setup >
Installation > Front of Boat .
5 Select Up or Down to adjust the offset.
Setting a Custom Park Position
