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

↓ 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 impor-
tant, you can calibrate the depth indicators so that they show the ac-
tual 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 en-
tered 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.
