3.35Optimize the quality of the radar display

To change the range:

1.Display the Radar screen and control panel. Select In or Out to change the range by one step, and then repeat this until the Radar screen is at the desired range.

3.35Optimize the quality of the radar display

Common problems that can degrade the radar display include:

•sea clutter

•rain clutter

•interference from other radars

•false echoes (sometimes called ghost echoes) and background noise

•side lobe patterns (false echoes that appear as an arc or a broken arc)

•shadows (blind spots)

•multiple echoes off the same object

You can optimize your radar display to reduce the effects of sea clutter, rain clutter, and interference from other radars. You can also change the radar sensitivity to reduce false echoes with the gain setting.

If the radar is installed at a suitable height and in a suitable location on your vessel, side lobe patterns and shadows (blind spots) caused by obstructions such as funnels or masts will be minimized. If you're having problems with these, you may need to relocate the radar. Consult the Installation Guide for your radar model, or talk to your dealer or installer.

Multiple echoes off the same object are most likely to occur when you are close to a large target and are usually only a temporary nuisance.

3.36Change the radar gain mode

Use the radar gain mode to specify whether you want to adjust the radar gain yourself or let the 8000i adjust it automatically. Any changes are global and apply to all the Radar screens. Auto is the default.

(If the radar Gain Mode is set to Auto and you adjust the gain setting manually, the Gain Mode is changed to Manual.)

To change the radar gain mode:

1.Display the Radar screen and control panel. If you can't see the Adjust Radar button, select Return.

2.Select Adjust Radar.

3.Select Gain Mode and a drop down list appears. There are three choices:

Manual. Select this to adjust the radar gain yourself to suit your local conditions and preferences. The manual gain setting will be applied at all radar range settings.
