MAINTENANCE

2.1 Maintenance
WARNING
ELECTRICAL SHOCK HAZARD
Do not open the equipment.
Only qualified personnel
are permitted to work inside
the equipment.
Regular maintenance
Check the following points regularly to maintain performance.
• Check that the connectors on all units of the system are firmly fastened and free of rust. Clean
if soiled or corroded.
• Check that all ground wires are tightly fastened.
• Check for dust or dirt on the LCD. Wipe the LCD carefully to prevent scratching, using tissue
paper and an LCD cleaner. To remove dirt or salt deposits, use an LCD cleaner, wiping slowly
with tissue paper so as to dissolve the dirt or salt. Change paper frequently so the salt or dirt
will not scratch the LCD. Do not use solvents such as thinner, acetone or benzene for cleaning.
Also, do not use degreaser or anti-fog solution, as they can strip the coating from the LCD.
Transducer maintenance
Marine life (barnacles, etc.) adhering to the transducer face can reduce sensitivity. Periodically re-
move any marine life from the transducer face with fine sandpaper or a piece of wood.
Do no paint the transducer face. Performance will be affected.
NOTICE
Items containing organic solvents (rust
inhibitors, electrical contact spray, etc.)
must not be used on painted and plastic
parts of the equipment.
Plastic parts and paint may be damaged.
