number shows a minus (–) sign instead of the plus (+) sign.

3. Press 

↓ until the number shows – 3.5, then press 

. The depth

indicators now accurately show the depth of water beneath the keel.

NOTE:

If knowing the exact depth of water beneath the keel is less
important, you can calibrate the depth indicators so that they show
the actual water depth from surface to bottom. To do this, first
measure the distance from the face of the transducer up to the surface
(the water line on the boat). In this example, we will use 1.5 feet. This
will be entered as a positive 1.5 feet, which makes the depth
indicators perform as if the transducer's higher in the water than it
really is.
