Chapter 3: Maintenance and Problem
Solving
This chapter provides information on routine maintenance and on possible causes
of problems you may experience with your DSM300.
3.1 Maintenance
CAUTION:
The sounder unit contains high voltage. Adjustments require
specialized service procedures and tools only available to
qualified service technicians. There are no user serviceable parts
or adjustments and the operator should not attempt to service
the equipment. The operator should not remove the rear cover of
the module.
Routine Checks
The DSM300 is a sealed unit. Maintenance procedures are therefore limited to the
following periodic checks:
• Examine the cables for signs of damage, such as chafing, cuts or nicks.
• Check that the cable connectors are firmly attached.
Cleaning Instructions
Cleaning the Module
The DSM300 is a sealed unit and does not require regular cleaning. However, if
you find it necessary to clean the unit, please follow these basic procedures:
• Ensure power is off.
• Wipe the module clean with a damp cloth.
• If necessary, use IPA (isopropyl alcohol) or a mild detergent solution to
remove grease marks.
Cleaning the Transducer
Sea growth can collect quickly on the bottom of the transducer, this can reduce
the performance in just a few weeks. To prevent the build-up of sea growth, coat
the transducer with a thin layer of paint.
