NOTE: GMR Fantom and xHD2 radar models support two no-transmit zones.
Other GMR radar models support one no-transmit zone.
1 From a radar screen, select MENU > Radar Setup > Installation >
Enable No Xmit Zone.
The no-transmit zone is indicated by a shaded area on the radar screen.
2 Select Adjust No Transmit Zone > Move No Transmit Zone.
3 Select Angle 1, and select the new location for the first angle.
4 Select Angle 2, and select the new location for the second angle.
5 Select Done.

Adjusting the Radar Range

The range of the radar signal indicates the length of the pulsed signal
transmitted and received by the radar. As the range increases, the radar
transmits longer pulses in order to reach distant targets. Closer targets,
especially rain and waves, also reflect the longer pulses, which can add noise
to the radar screen. Viewing information about longer-range targets can also
decrease the amount of space available on the radar screen for viewing
information about shorter-range targets.

Tips for Selecting a Radar Range

• Determine what information you need to see on the Radar screen.
For example, do you need information about nearby weather conditions
or targets and traffic, or are you more concerned about distant weather
conditions?
• Assess the environmental conditions where the radar is being used.
Especially in inclement weather, longer-range radar signals can increase
the clutter on the Radar screen and make it more difficult to view
information about shorter-range targets. In rain, shorter-range radar
signals can enable you to view information about nearby objects more
effectively, if the rain clutter setting is configured optimally.
• Select the shortest effective range, given your reason for using radar and
the present environmental conditions.

Marking a Waypoint on the Radar Screen

1 From a radar screen, select a location.
2 Select New Waypoint.
MotionScope™ Doppler Radar Technology
The GMR Fantom radar uses the Doppler effect to detect and highlight
moving targets to help you avoid potential collisions, find flocks of birds, and
track weather formations. The Doppler effect is the frequency shift in the
radar echo due to the relative motion of the target. This allows for instant
detection of any targets moving toward or away from the radar.
The MotionScope feature highlights the moving targets on the radar display
so you can navigate around other boats or severe weather, or toward fishing
spots where birds are feeding at the surface.
