ON-BOARD MAINTENANCE
Introduction
This section deals with maintenance work that may be carried
out by the user. In addition to cleaning the cabinets and dust
filters, you should inspect the sonar room at least once a week.
The ventilation and heating system, as well as the bilge pump
arrangement should then be checked to be in good working
order.
For location and replacing of fuses, refer to the chapter for the
unit in question.
Major repairs and complete overhaul of the sonar must be left to
an authorized Simrad service engineer.
