Section Five: Using Manual Control Functions; Gain And Clutter Adjustments - NorthStar 6000i Installation Manual

control functions
This section contains an overview of the radar's manual control functions and how to use them. All
radar adjustments take effect immediately — pressing ENT , Done or Return is not necessary.
Some of the functions described in this section are found only in Northstar software version 8.0 and
later, and in Northstar 6000i software version 1.61 and later.

Gain and clutter adjustments

The Mode, Rain Clutter, Sea Clutter and Gain can be set to automatic mode to obtain an excellent
image under most conditions. Some situations may require manual settings.
To access these manual controls, press Page 2 from the main radar screen.
The Mode key has the following settings:
• Auto 1 and Auto 2 are for normal, open-water use.
• 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 and clutter settings for that range are reapplied. In addition, the Sea State control can
apply further adjustments to sea clutter over all ranges as needed for current conditions.
• Manual provides fully manual control, in which the user usually needs to adjust the
settings each time the range is changed.
Automatic settings are described on page 18, "Adjusting the appearance settings. "
Manual settings directly control Rain Clutter, Sea Clutter and Gain. They may be applied in either of
two ways, depending on the setting of the Mode control on this screen.
• Mode = Manual: settings usually need to be adjusted every time the range is changed
• Mode = Range Rider: settings are saved separately for each range, and the last-used
settings for each range (modified by the sea state control) are reapplied when that range is
selected
