NorthStar 6000i Installation Manual page 27

• Auto 1 and Auto 2 are for normal, open-water use. The two automatic modes can be
optimized for two different conditions.
• Harbor automatically optimizes the radar settings for use in a harbor.
• Range Rider is a Northstar exclusive feature recommended when manual settings are
required. The user can freely make any needed gain and clutter adjustments, and these
settings are "remembered" for each range. When the range is selected again, the last-used
gain setting for that range is reapplied.
• Manual is a fully manual function in which the user will usually need to adjust the settings
each time the range is changed.
In the recommended automatic modes (Auto1, Auto2, and Harbor), the unit continuously evaluates
its settings and adjusts them as necessary to obtain the best image. Gain and clutter are evaluated
separately in various areas of the screen, and the settings are optimized for each area. Breaking
waves often cause stronger clutter echoes on one side of the vessel than on the other, and automatic
mode can optimize the image for each area.
Optimizing Automatic mode
Use the automatic settings described below to adjust the appearance of the radar image to your
preference, and the radar will attempt to maintain this appearance over a variety of conditions by
monitoring the signals and making adjustments as conditions change.
The appearance settings are set to values shown in Table 11 when the unit leaves the factory or
when the Restore settings function is used. These values typically provides a useful picture, but the
installer should check and fine-tune these values for each range and for each mode (Auto1, Auto2
and Harbor). The installer might choose to make Auto1 produce a slightly light picture, and Auto 2
slightly darker picture. Or, the two modes could be optimized for different conditions or uses of the
radar.
