Radar Scanner and Antenna Settings
Setting the Antenna Rotation Speed
Note: You can set the rotation speed for GMR 18, 18 HD, 24, 24 HD, 404, 406, 404 xHD, 406xHD,
604 xHD, 606 xHD, 1204 xHD, or 1206 xHD radar only. The antenna does not rotate at high speed in Dual
Range mode.
1. From the Home screen, select Radar > Radar Setup > Rotation Spd.
2. Complete an action:
• Select Normal Speed.
• Select High Speed to increase the speed at which the antenna rotates, which increases the speed at
which the screen updates.
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 configured” message appears.
Note: You can set the antenna size for GMR 404, 406, 404 xHD, 406 xHD, 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 Configuring 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 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.
2. Select Angle 1 > Adjust > Move.
3. Select Up or Down to adjust the size of the no-transmit zone.
4. Select Angle 2 > Adjust > Move.
5. Select Up or Down to adjust the size of the no-transmit zone.
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 potential front-of-boat offset (see previous
procedure).
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. From the Home screen, select Radar > Radar Setup > Front of Boat.
2. Select and hold Up or Down to adjust the offset.
