Deep Alarm
The deep alarm adjusts the same as the shallow alarm.  Use the “DEEP
ALARM” menu to adjust the deep alarm.  When the bottom signal goes
deeper than the setting, an alarm tone sounds.

LIGHTS
The display is backlighted for night use.  To
turn the backlights on or off, press the menu
key repeatedly until the BACK LIGHT menu
appears.  Now press the up arrow to turn the
lights on or the down arrow to turn them off.

FEET/METER
This unit can show the depth in feet or meters.
When it is in the metric mode, all depth
readings, ranges, zooms, and alarm settings
are in meters.  When it's in the feet mode, all
of the above settings are in feet.

To change from feet to meters or vice-versa,
press the menu key until the FEET/METER
menu appears.  Press the down arrow key to
switch to metric, the up arrow to switch to feet.
Displays show in feet when the unit is first
turned on.  The menu will clear automatically
after a few seconds or you can press the
PWR key to clear the screen.

DISPLAY CONTRAST
The unit’s display contrast is adjustable to suit
different lighting conditions.  This will help you
see the screen from different angles, or at
various times of the day.

To adjust the contrast, press the menu key
until the DARK/LIGHT menu appears.  To
decrease it, press the down arrow key.  Press
the up arrow key to increase the contrast.
The bar graph in the Dark/Light menu box
shows a graph of the contrast.  The screen
will also show the effects of the change.  If you
