DISPLAY ZOOM BAR
When the unit is in the split-screen
zoom mode, the zoom bar doesn’t
normally show on the screen. The
zoom bar shows the section of water
on the right side of the screen that is
being enlarged on the left side. To turn
the zoom bar on continuously when
the split-screen mode is on, highlight
the "Show Zoom Bar" on the "Chart
Setup" menu, then press the right ar-
row key. Now press the EXIT key. If
you're not in the split-screen mode,
change to that mode. A screen similar
to the one at right appears.
To turn the zoom bar off, repeat the above steps.
DISPLAY ZONE BAR
The zone alarm consists of a bar. Any
echoes that appear between the top
and bottom of this bar triggers the
zone alarm. This bar normally doesn't
show on the screen. To turn the zone
bar on continuously, highlight the
"Show Zone Bar" on the "Chart Setup"
menu, then press the right arrow key.
Now press the EXIT key. A screen
similar to the one at right appears. To
turn the zone bar off, repeat the above
steps.
See the Alarms section for more information on the zone alarm.
DIGITAL SONAR
When the unit is first turned on, the digital depth display is located at the
top left corner of the screen. This display comes from a separate digital
sonar built into the unit (and into the optional SAM-50HPD). It displays only
the bottom depth. If it loses the bottom, the last known depth will flash on
the display. When the digital regains the bottom, it automatically shows the
bottom depth again.
