Instruction manual

SETUP menu Chapter 11-3
Depth DS fish - define a specific area below the water surface of
minimum and maximum depth for the fish alarm.
Depth DK alarm min. and max. - set up a depth limit alarm for
depth below keel.
Water profile - choose between SALT and FRESH water. The set-
ting will reflect on the:
Velocity of sound in water: SALT = 1470 meters per second and
FRESH = 1430 meters per second as standard. The standard set-
tings can be even more accurate by slightly increasing the number of
meters in warm waters and decreasing in cold waters.
Time/distance scale - will indicate the elapsed time or distance for
the echo picture. The readout will appear in the upper part of the
echo display. Toggle between time and distance in “Scroll synchro-
nisation”, section 4.7.
Restart of AUTO pulse/power - will automatically restart the
echosounder if bottom detection has been lost for the chosen time
interval i.e. 10, 20 or 40 seconds. The AUTO pulse and power will
restart from 10W and SHORT pulse.
Echo sampling - is preset to BOTTOM, which enables auto range
and a view all the way to the bottom. For vessels moving at high
speed with the risc of losing bottom detection, RANGE or a max.
depth setting (50 to 2000m) is recommended. The unit will not wait
for a bottom echo, but transmit a new pulse as soon as the selected
range has been reached. Auto range is automatically switched off.
The depth alarm setting will have a higher priority than the selected
depth range.
Demo mode - the echosounder will function as though a transducer
was connected, but all data presented in the display will be simu-
lated.
