Setting the Radar Antenna Size
You can indicate the size of the radar antenna in order to optimize the radar picture. Until you
specify the antenna size, the “Radar needs to be congured” message appears.
NOTE: You can set the antenna size for GMR 404, 406, 604 xHD, 606 xHD, 1204 xHD, or 1206
xHD radar only.
1. From the Home screen, select
Radar > Radar Setup > Antenna Size.
2. Select
4 Foot or 6 Foot.
Turning On and Conguring a Radar No-transmit Zone
You can indicate an area within which the radar scanner does not transmit signals.
NOTE: You can set a radar no-transmit zone for GMR 604 xHD, 606 xHD, 1204 xHD, or 1206
xHD radar only.
1. From the Home screen, select
Radar > Radar Setup > Enable No-transmit Zone.
The no-transmit zone is indicated by a shaded area on the Radar screen.

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.
Measuring the Potential Front-of-boat Offset
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°, set the front-of-boat offset.
Setting the Front-of-boat Offset
Before you can set the front-of-boat offset, you must measure the front-of-boat offset (page 95).
The front-of-boat offset setting congured for use in one radar mode is applied to every other radar
mode and to the Radar Overlay.
1. From the Home screen, select
Radar > Radar Setup > Front of Boat.
2. Select and hold
Up or Down to adjust the offset.
