3.Use 
and 
to change the value. If either key is held depressed for more than one second the reading will increase or decrease rapidly.
4.When the alarm is set, exit by pressing both 
and 
simultaneously. Alternatively, if no keys are pressed for a period of 5 seconds the normal depth display will resume.
ONOFF
Press simultaneously to exit
Note: If the reading is increased one step above 600 feet (or equivalent) the display will show OFF and the alarm will be disabled. The alarm can also be disabled by pressing both 
and 
for 5 seconds. The word OFF will be displayed but the alarm depth will be retained for future use.
2 Instrument Setup
Keel/Surface Offset
An offset may be automatically added to or subtracted from the depth reading to compensate for the location of the transducer. This allows the instrument to indicate the water depth relative to the bottom of the keel or the surface of the water.
To set the keel/surface offset:
1. Apply power while holding down 
.
ON
Hold down during power up
2.When the unit is on, release 
. The display will indicate if the current offset is keel offset or waterline offset:
Hull Offset (Depth below the keel)
Surface Offset (Depth below the surface)
3.After 5 seconds the display will indicate the current offset.
Note: A negative offset is used to display depth below the keel and a positive offset is used to display depth below the surface.
4.Use 
and 
to change the value. If either key is held depressed for more than one second the reading will increase or decrease rapidly.
5.The offset can be programmed in 0.1 unit steps from
6.To display depth below the keel enter the vertical distance between the bottom of the keel and the depth transducer as a negative value.
7.To display depth below surface enter the vertical distance from the waterline to the depth transducer as a positive number (no negative sign).
8.To exit this mode, press and hold both 
and 
simultaneously. Alternatively, if no keys are pressed for a period of 5 seconds normal depth display will resume.
ONOFF
Press simultaneously
The display will now indicate the current water depth.
