Depth Alarm
 Menu Settings: Off
 Adjustment: 1 foot to 99 feet (1 to 30 meters)
The Depth Alarms sounds a tone and the Depth Alarm Indicator will blink when the bottom depth gets shallower than the Depth Alarm's
setting.
WARNING: Do not use this feature for shallow water navigation.
Battery Alarm
When the battery voltage drops below the set value, the alarm sounds. This ensures you can tell your friends about the big fish you
caught with the help of SonarPhone on Facebook before the battery goes dead.
Advanced Menu
Bottom Lock
When ON the bottom signal stays locked on bottom as you move. SonarPhone automatically adjust to keep the bottom locked into a
single position. This is useful when looking for targets close to the bottom when there are heavy waves on the surface.
Keel Offset
Keel Offset will adjust the digital depth readout to indicate depth from the waterline or boat's keel instead of from the transducer position.
Enter a positive vertical measurement from the transducer to the waterline. Enter a negative vertical measurement from the transducer
to keel to read the depth from the keel.
Display Color Options
Select the color scheme that works best for you: White Background, Blue Background or Gray Scale.
Surface Clarity
 Menu Settings: Off, High, Medium, Low
Surface Clarity adjusts the filter that removes surface clutter noise caused by algae and aeration. The lower the setting, the more
surface clutter will be displayed. Increasing surface clutter reduces SonarPhone's ability to display small targets.
Noise Filter
 Menu Settings: Off, High, Medium, Low
The Noise Filter system built into SonarPhone constantly evaluates the effects of boat speed, water conditions and interference on the
clarity of your display. This automatic feature gives you the best display possible under most conditions. If you have high noise levels,
try using the "High" setting.
IMPORTANT: If you are having trouble with noise (electronic interference), we suggest that you take steps to find the interference
source and correct it, rather than continually using the unit with the high setting.
