Zone Alarm Bar
The zone alarm has a range 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, select “ZONE BAR” from the
“CHART DISPLAY” menu, then press the right
arrow key. Now press the EXIT key. A screen simi-
lar 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.
CHART CURSOR
This unit has a chart cursor that allows you to
pinpoint a target’s depth. The cursor is simply a
horizontal line that extends across the display
from left to right. A depth box at the end of the
line on the right side shows the line’s depth. In
the example at right, the cursor (line) is at 41.1
feet.
To display the chart cursor, press the MENU key
and select “SONAR SETUP”, then select “USE DEPTH CURSOR”. A
screen similar to the one at right appears. Use the up and down arrow
keys to move the cursor up or down to the desired depth.
To turn the chart cursor off, simply press the EXIT key.
DIGITAL SONAR
Normally, 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. It displays only the bottom depth. If it loses the bottom, the last known
depth will flash on the display. When the digital finds the bottom, it will
automatically display the bottom depth again. The digital sonar can be
turned off, however this also turns all automatic features off also, such as
auto sensitivity, auto ranging, and the Fish ID. feature.
To turn the digital off, first press the MENU key and select “SONAR
SETUP”, then select “DIGITAL SONAR”. Press the left arrow to turn it off.
CAUTION!
Turning the digital sonar off also turns the automatic mode off, including
Fish ID, and the depth alarms.
