1 From a radar screen or the radar overlay, select Menu > Radar Filters > Sea Clutter. 2 Select an option:. • Select an Auto option based on the sea conditions. • Select Up or Down to adjust the appearance of sea clutter until other targets are clearly visible on the radar screen. Select a setting that reflects the present sea conditions. Clutter caused by sea conditions may still be visible. When using a compatible radar model, the chartplotter adjusts the sea clutter based on the sea conditions automatically. Adjusting Rain Clutter on the Radar Screen You can adjust the appearance of clutter caused by rain. Reducing the radar range also can minimize rain clutter (Adjusting the Radar Range, page 35). The rain clutter setting affects the appearance of nearby rain clutter and targets more than it affects the appearance of distant rain clutter and targets. A higher rain clutter setting reduces the appearance of clutter caused by nearby rain, but it can also reduce or eliminate the appearance of nearby targets. NOTE: Depending upon the radar in use, the rain clutter settings configured for use in one radar mode may or may not be applied to other radar modes or to the radar overlay. 1 From a radar screen, select Menu > Radar Filters > Rain Clutter. 2 Select Up or Down to decrease or increase the appearance of nearby rain clutter until other targets are clearly visible on the radar screen. Clutter caused by rain may still be visible. Averaging Multiple Scans on the Radar Screen You can average the results of multiple scans on the radar screen. This can be an effective method to filter out noise and enhances the detection of consistent targets. Averaging is most effective when using a longer range. 1 From a radar screen or the radar overlay, select Menu > Radar Filters > Scan Average. 2 Select an option. The High setting filters out the most noise. Radar Options Menu From a radar screen, select Menu > Radar Options. MotionScope™: Uses the Doppler effect to detect and highlight moving targets to help you avoid potential collisions, find flocks of birds, and track weather formations (MotionScope™ Doppler Radar Technology, page 35). This option is only available on Fantom models. Pulse Exp.: Increases the duration of the transmit pulse, which helps maximize the energy directed toward targets. This helps to enhance the detection and identification of targets. This option is only available on xHD radome and xHD2 open array models. Target Size: Adjusts the size of targets, by adjusting the pulse compression processing. Select smaller targets for a sharp, high resolution radar image. Select larger targets to display larger echos for point targets, like boats and buoys. This option is only available on Fantom models. Echo Trails: Enables you to track the movement of vessels on the radar screen. This option is not available on xHD open array or HD/HD+ radome models. 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 36). Guard Zone: Sets a safe zone around your boat and sounds an alarm when anything enters the zone (Enabling a Guard Zone, page 35). Timed Transmit: Helps conserve power by transmitting radar signals at set intervals. Radar Setup Menu From a radar screen, select Menu > 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. Orientation: Sets the perspective of the radar display. Crosstalk Rej.: Reduces the appearance of clutter 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 cross talk reject setting is on. NOTE: Depending upon the radar in use, the cross talk reject setting configured for use in one radar mode may or may not be applied to other radar modes or to the Radar overlay. From a Radar screen or the Radar overlay, select Menu > Radar Setup > Crosstalk Rej.. Radar Appearance Settings From a radar screen, select Menu > Radar Setup > Appearance. NOTE: These settings do not apply to the radar overlay. Bkgd. Color: Sets the color for the background. Frgd. Color: Sets the color scheme for the radar returns. Brightness: Sets the brightness of various radar features, such as range rings and tracking symbols. Look-Ahead Speed: Shifts your present location toward the bottom of the screen automatically as your speed increases. Enter your top speed for the best results. Radar Installation Settings Front of Boat: Compensates for the physical location of the radar when it is not on the boat axis (Front-of-Boat Offset, page 38). Antenna Configuration: Sets the radar antenna size and sets the position in which the radar stops (Setting a Custom Park Position, page 39). No Transmit Zone: Sets the area in which the radar does not transmit signals (Enabling and Adjusting a Radar No Transmit Zone, page 35). 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 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. 1 Using a magnetic compass, take an optical bearing of a stationary target located within viewable range. 38 Radar

Clutter caused by sea conditions may still be visible.

When using a compatible radar model, the chartplotter adjusts

the sea clutter based on the sea conditions automatically.

Adjusting Rain Clutter on the Radar Screen

You can adjust the appearance of clutter caused by rain.

Reducing the radar range also can minimize rain clutter

(

Adjusting the Radar Range

, page 35

The rain clutter setting affects the appearance of nearby rain

clutter and targets more than it affects the appearance of distant

rain clutter and targets. A higher rain clutter setting reduces the

appearance of clutter caused by nearby rain, but it can also

reduce or eliminate the appearance of nearby targets.

NOTE:

Depending upon the radar in use, the rain clutter settings

configured for use in one radar mode may or may not be applied

to other radar modes or to the radar overlay.

Averaging Multiple Scans on the Radar Screen

You can average the results of multiple scans on the radar

screen. This can be an effective method to filter out noise and

enhances the detection of consistent targets. Averaging is most

effective when using a longer range.

Target Size

: Adjusts the size of targets, by adjusting the pulse

compression processing. Select smaller targets for a sharp,

high resolution radar image. Select larger targets to display

larger echos for point targets, like boats and buoys. This

option is only available on Fantom models.
