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 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.
