Important Information

Intended Use

Raymarine DSM25 Digital Sounder Modules provide echo sounder data that can
be displayed on A65 Multifunction Display units. DSM25s are intended for
recreational depth finding and fish finding purposes.
Echo sounder systems require an appropriate Raymarine transducer unit and
inter-connecting cable. Depending on the type of transducer connected, the
DSM25 can also display temperature, distance traveled, and/or speed.
This manual contains important information for installing and operating your
DSM25. To get the best results in operation and performance, please take the time
to read this handbook thoroughly. Raymarine's Technical Services representatives
or your local dealer will be available to answer any questions you may have.
For full details on system integration, please refer to the handbook supplied with
the A65 display.

Safety Notices

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:
WARNING: Electrical Safety
The DSM25 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.
Make sure the power supply is switched off before making any
electrical connections.
WARNING: Transducer Cable
Removing the transducer cable from the rear of the sounder
module while it is switched on can cause sparks. Only remove the
transducer cable after power has been removed from the A65
display unit, which supplies power to the DSM. As with any
electronic device, be sure the sounder module is mounted where it
is well ventilated and free from gasoline fumes.
