Preface
Purpose
Raymarine DSM300 Digital Sounder Modules provide echo sounder data that can
be displayed on Raymarine E Series, C Series, and hsb
2
PLUS (Pathfinder) Series
display units. This handbook describes operating the DSM300 with hsb
2
PLUS
Series displays. Instructions for using the DSM300 with E Series and C Series
displays are available in the handbooks for those products. The DSM300 will not
work with older HSB (non-PLUS) displays.
DSM300 Digital Sounder Modules are intended for recreational depth finding and
fishfinding purposes. Echo sounder systems require an appropriate Raymarine
transducer unit and inter-connecting cable.
To obtain the best results in DSM300 operation and performance, please read this
handbook thoroughly. Raymarine’s Technical Services representatives or your
local dealer will be available to answer any questions you may have.
SAFETY NOTICE
This equipment must be installed and operated in accordance with the
instructions contained in this manual. Failure to do so can result in personal injury
and/or navigational inaccuracies. In particular:
CAUTION: High Voltage
The DSM300 contains high voltages. Adjustments require specialized service
procedures and tools only available to qualified service technicians – there are no
user serviceable parts or adjustments. The operator should never remove the
cover or attempt to service the equipment.
CAUTION: Transducer Cable
Removing the transducer cable from the rear of the DSM300 while the sounder
module is powered on can cause sparks. Only remove the transducer cable after
power has been removed from the DSM300. As with any electronic device, be
sure the sounder module is mounted where it is well ventilated and free from
gasoline fumes.
If the transducer cable is accidentally removed while the DSM300 is powered on,
remove power from the sounder module, replace the transducer cable, and then
return power to the module. As a safety feature, the DSM300 only recognizes that
the transducer is connected at power-up.
