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, automatic anti-clutter, pulselength and noise rejector settings.
Adjusting these features on a function key menu changes the original function key settings.
To restore the original settings for a particular function key, it is necessary to display the
relevant function key menu and select appropriate menu options.
Note: Function key presetting requires a good knowledge of optimum radar settings. If you
want to change the original function key settings, consult your nearest FURUNO
representative or dealer.

Most often used controls are placed on the center panel while less often used controls are

settings at the time of installation.
- Target trails (See paragraph 1.25.)

Provided that the function key is assigned the specific operation feature, press the key to instantly
set the radar for the preset purpose. The corresponding label will be displayed at the left margin of
the screen. If you re-press the function key, the radar returns to the previous settings.
