This chapter has information about maintenance and troubleshooting that the user 
can follow to care for the equipment.

Routine maintenance helps keep your equipment in good condition and prevents fu-
ture problems. Check the items shown in the table below on a regular basis to help 
keep your equipment in good condition for years to come.

Cables

Cable connection, corrosion

Connect the cables that have loosened. Replace 
any damaged cables.

Cabinet

Dust on the cabinet

Remove dust with a dry clean cloth. Do not use 
commercial cleaners to clean the equipment - they 
can remove paint and markings.

LCD

Dust on the LCD

Wipe the LCD carefully to prevent scratching, us-
ing 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 antifog solution, as they can 
strip the coating from the LCD.

Waterdrops on the LCD

Waterdrops on the LCD can slow touch response. 
Wipe the LCD with a dry cloth to remove the water.
