Figure 4-4: Single Channel Display
The large window at the right-hand side of the information area is used to display the
actual water depth, the measurement mode, units of measurement. The measurement
mode can be either:

Depth Below the Keel = DBK (as shown)

Depth Below the Surface = DBS

Depth Below the Transducer = DBT
The units of measurement can be either:

Meters (m; as shown)

Feet (ft)

Fathoms (ftm)
WARNING!
If no valid bottom depth is available, instead of the depth value a “?” appears.
The reason can be loss of the bottom signal by distortion or other influence
or the bottom depth is out of the selected range.
Therefore in case of the “?” appearance check the selected range and the
analogue bottom trace.
While crossing steep slopes, the echo evaluation might fail. A steady depth
display cannot be guaranteed in this case. The depth display will show the
last evaluated depth value together with a question mark; longer lasting errors
will be indicated by a question mark without any depth value. At the digital
slave display "----" will be displayed in this case.
