Each picture setup option defines a com-
bination 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,
pulsewidth 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 neces-
sary to display the relevant function key
menu and select appropriate menu op-
tions.
Note: Function key presetting requires a
good knowledge of optimum radar set-
tings. If you want to change the original
function key settings, consult your near-
est FURUNO representative or dealer.
