This chapter provides information on routine maintenance and on possible
causes of problems you may experience with your HD Series system.
9.1 Maintenance
WARNING:
These units 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 units.
WARNING:
REMOVAL OF A UNIT’S COVER BY ANYONE OTHER THAN
QUALIFIED SERVICE TECHNICIANS WILL VOID THE
WARRANTY.
Switch off the display unit before removing the power cord. Power off the
display unit and DSM250 before removing the transducer cable.
CAUTION:
Removing the transducer cable from the fishfinder display or the
DSM250 while the unit is powered on can cause sparks. Only remove the
transducer cable after power has been removed.
Routine Checks
The LCD display and Digital Sounder Module are sealed units. 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.
