To turn on or turn off Radar Echo Expansion:
Highlight RADAR ECHO EXPANSION on the radar menu, then press ENT to
turn it on (check) or turn it off (uncheck). Press
EXIT to clear the radar
menu. Radar Echo Expansion is good for seeing weak echo returns —
like birds — at a distance.
Remember, when Echo Expansion is on, all signals on the display will
be enlarged, including clutter.
Echo Trail Interval
This option allows you to compile a history (trail) of the movements of
all radar targets via preset intervals.
To adjust Echo Trail Interval
1. Select ECHO TRAIL INTERVAL from the radar menu and press ENT, which
will launch the Echo Trail Interval menu.
2. The Echo Trail Interval menu will display a series of intervals with
options ranging from Continuous to Off. Use ↑ ↓ to highlight the de-
sired interval and press
ENT. Press EXIT to get back to clear the menu.
NOTE:
This feature is best used in open water or when your vessel is sta-
tionary and you are tracking a moving target. If Echo Trail Interval
is on and your vessel is moving, the display will be crowded with
trails for every target, including stationary targets, like lighthouses
and land.
Clear Radar Trails
This feature is used to clear radar trails created with the Echo Trail
Interval command.
To clear radar trails:
Highlight CLEAR RADAR TRAILS on the radar menu and press ENT. All ra-
dar trails are now cleared off the radar display.
