This chapter provides information on routine maintenance and on possible
causes of problems you may experience with your DS400/500.

7.1 Maintenance

CAUTION:
This 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

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 Unit
The DS400/500 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.
