Automatic Picture Setup According To Navigation Purpose - Furuno FA Manual

1. RADAR OPERATION
1.33 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 the buoy detecting function and labeled SHIP on the
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 may 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 Optimum setting for detecting
BUOY navigation buoys, small vessels and
other small surface objects at close
range
ROUGH Optimum setting for rough weather
SEA 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. Those involved are
interference rejector, echo stretch, echo average, noise rejector, automatic
anti-sea and anti-rain clutters, video contrast, pulselength 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 choose the default setting. For this reason, we recommended
that you use the user-programmable function sets when frequent adjustment of
the radar picture is necessary.
