Before installing the system cables consider the following
points
Power transducer and network cables need to be attached
to the unit

Raymarine DSM400 Digital Sounder Module
Cables should be adequately secured protected from
physical damage and protected from exposure to heat 1 The figures assume a constant current of 7A
regardless of input voltage
Avoid running cables through bilges or doorways or close
to moving or hot objects 2 Cable length is the distance between the power source
and the unit
Avoid sharp bends 3 These wire sizes give a total drop of about 05 V
Use a watertight feedthrough wherever a cable passes between the power source and the unit achieving a
through an exposed bulkhead or deckhead minimum voltage at the unit of 105 V with a fully flat
battery at 11V
Secure cables in place using tiewraps or lacing twine Coil
any extra cable and tie it out of the way
Transducer cable
Power cable Raymarine does not recommend extending the power cable should be run as a single
length of cable from cable However if this is unavoidable contact your local dealer

Common problems and their solutions
Problem Solution
Display freezes 1 Check that the scroll speed is not set to zero
2 Check the transducer cable for damage If damaged the cable and transducer must be replaced as a
unit
Sounder does not display fish 1 Fish arches are not displayed if the boat has stopped fish will appear on the display as a
straight line
2 Ensure the transducer is within 10 degrees of vertical
3 Check that the gain is not set too low
Sounder does not see bottom or fish 1 Check that the gain is not set too low
2 Ensure the transducer is within 10 degrees of vertical
3 Check that the transducer face is not covered or fouled If necessary clean the transducer
4 Check the voltage from the power source If it is too low it can affect the transmitting power of the
sounder
Sounder displays a lot of background noise 1 Check that the gain is not set too high
2 Check that the transducer is mounted correctly and is clean
Sounder temperature readings are wrong If necessary adjust the TEMP CALIBRATE parameter
Sonar display is unreliable at high boat speeds Turbulence around the transducer may be confusing the unit Check the transducer
