Automatic Picture Setup According To Navigation Purpose - Furuno FCR-2107 Series Operator's Manual

2.22 Automatic Picture Setup According to Navigation
Purpose
Every time your navigating environment or task changes, you must adjust the radar, which can be a nuisance in a
busy situation. Instead of changing radar settings case by case, it is possible to assign the function keys to provide
optimum settings for often encountered situations.
The radar's internal computer offers several picture setup options to be assigned to each function key for your
specific navigating requirements. For instance, one of the functions is assigned to detect ships and labeled SHIP on
the PICTURE box. By choosing SHIP, the radar will be instantly set for optimum detection of ships.
Four user-programmable setups are also provided (labeled PICTURE1-PICTURE4), so that you can have the radar
automatically adjusted to those conditions which are not covered by the provided setup options.
Below are the preset picture setup options provided with this radar.
Label
NEAR Optimum setting for short range
detection using a range scale of 3
nm or less on calm seas
NEAR BUOY Optimum setting for detecting
navigation buoys, small vessels and
other small surface objects at close
range
ROUGH SEA Optimum setting for rough weather
or heavy rain
HARBOR Optimum setting for short range
navigation in a harbor area using a
range scale of 1.5 nm or less
Each picture setup option defines a combination of several radar settings for achieving optimum setup for a
particular navigating situation. These include interference rejector, echo stretch, echo average, noise rejector,
automatic anti-sea and anti-rain clutters, video contrast, pulse length and sea and radar conditions.
Adjusting these features from the PICTURE menu changes the original function key settings. To restore the original
settings for a particular picture setup option, it is necessary to select the default setting. For this reason, we
recommended that you use the user-programmable function sets when frequent adjustment of the radar image is
necessary.
