Furuno 1724C 사용자 설명서

 

This chapter provides information necessary for keeping your unit in good working order 
and remedying simple problems. 

Hazardous voltage which can
cause electrical shock exists
inside the equipment. Only 
qualified personnel should 
work inside the equipment.

Those items contain organic solvents that 
can damage coating and plastic parts, 
especially plastic connectors.

 
 

Regular maintenance is important for optimum performance. A maintenance program 
should be established and should at least include the items shown in the table below. 

Display unit connectors  Check for tight connection. 

Tighten loosened connectors. 

LCD 

The LCD will, in time, 
accumulate a coating of dust 
which tends to dim the picture. 
Wipe LCD lightly with soft 
cloth to remove dust. 

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. 

Ground terminal 

Check for tight connection and 
corrosion. 

Clean or replace ground wire as 
necessary.
