2.5 Screen Group 1: Depth, Speed, Trip Log
There are five screens in this group (all have one or more sub
screens).
Screen 1
DEPTH
BOAT SPEED
TRIP LOG
• The upper screen section displays ‘DEPTH’, unit (e.g. ‘mtrs’)
and the depth value. An arrow indicates a rising (↑) or falling
(↓) bottom. A bargraph indicates the strength of the signal.
‘EXT’ replaces the bargraph if the depth signal is from an
external source on NMEA format.
• The middle screen section displays ‘BOAT’, unit (e.g. ‘kts’)
and boat speed value.
• The lower screen section displays ‘TRIP’ and the trip log
value in nautical miles.
Note ! If the system depth transducer signal is lost, the Depth display
will flash the last good echo value for one minute, then it will
show ---. If there is an alternative depth input to the system on
NMEA format and the sounder is set to Off, this depth will be
displayed instead.
Screen 1 has three sub screens. Setting of the boat (water) speed
damping, switching the depth sounder on and off, and setting the
level of depth damping.
Speed damping
The displayed speed has four damping levels (0-3), 0=Off.
On power up the last set damping level is selected.
To change the speed damping level follow the procedure in
Figure 2-2, page 12 and select the wanted damping level. The
higher the figure the more damping.
To Set the Depth Sounder On or Off
In certain circumstances, e.g., to save power in known waters or
when out of depth range, you may want to turn the depth sounder
off. It is also recommended to turn it off if there is another
sounder on board operating on the same (200 kHz) frequency.
Interference between the two can thus be avoided.
