3. MAINTENANCE & TROUBLE-
SHOOTING
3.1 Maintenance
Regular maintenance is essential for good
performance. Checking the items listed in the
table below monthly will help keep your equip-
ment in good shape for years to come.
3.2 Care of Display
Unit
For the chassis, dust or dirt on the cabinet can
be removed with a soft, dry cloth. For stub-
born dirt, water-diluted mild detergent can be
used. In this case, wipe the cabinet with a dry
cloth after using detergent. Do not use sol-
vents such as thinner, acetone or benzene to
clean the unit. They can remove paint and
markings.
For the LCD screen, 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. Al-
so, do not use degreaser or antifog solution,
as they can strip the coating from the LCD.
3.3 Transducer Main-
tenance
Marine life on the transducer face will result in
a gradual decrease in sensitivity. Check the
transducer face for cleanliness each time the
boat is dry-docked. Carefully remove any ma-
rine life with a piece of wood or fine-grade
sandpaper.
