EMC Conformance

Preface
Conventions
All Raymarine equipment and accessories are designed to the best
industry standards for use in the recreational marine environment.
The design and manufacture of Raymarine equipment and acces-
sories conform to the appropriate Electromagnetic Compatibility
(EMC) standards, but correct installation is required to ensure that
performance is not compromised.
This handbook describes the Raymarine DSM250 Digital
Sounder Module (200/50 kHz).
This device must be connected to an
ter, or Fishfinder display unit to show echo sounder data. The
DSM250 will not work with older HSB (non-PLUS) displays.
Note: Older HSB (non-PLUS) display units must be upgraded to
before they can function with the DSM250.
Echo sounder systems require an appropriate Raymarine trans-
ducer unit and inter-connecting cable. Details for selecting and
installing the transducer are described in document number
81196, Transducers for Fishfinders Owner's Handbook.
This handbook contains very important information on the instal-
lation and operation of your new equipment. In order to obtain the
best results in operation and performance, please read this hand-
book thoroughly.
Raymarine's Technical Services representatives or your local
dealer will be available to answer any questions you may have.
Raymarine echo sounding (sonar) devices with integrated dis-
plays are known as Fishfinders. In this document, the DSM250—
which does not have its own display—is alternatively called a
Digital Sounder Module, Sounder, or just Module. The DSM250's
image data can be viewed on a display unit when that display is in
Sonar Mode.
