13. MAINTENANCE &
TROUBLESHOOTING
13.1 Maintenance
Regular maintenance is essential for good
performance. A maintenance program should
be established and should at least include the
items listed in Table 13-1.
Note:
The equipment may restart when certain
metallic parts on the rear of the display
unit are touched. This is caused by
static electricity. No operational error
occurs.
Do not open the equipment.
Hazardous voltage which can
cause electrical shock, burn or
serious injury exists inside the
equipment. Only qualified
personnel should work inside
the equipment.

marine life, which can reduce sensitivity. Gently scrape off any marine life from
the transducer with a piece of wood.
