REPLAY : When the user chooses to display information stored over the previous 24
operating hours (using the LOG DATA MENU), the word "REPLAY" will
appear here.
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:
• Metres = m (as shown)
• Feet = ft
• Fathoms = ftm
If instead of the depth value a ? appears, make sure, that the echo signal will be in the range
selected.
IMPORTANT NOTE: While crossing steep slopes the echo evaluation might fail. A steady
depth display cannot be guarantied in this case. The LAZ 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.
