7. MAINTENANCE, TROUBLE-
SHOOTING
7.1 Maintenance
Regular maintenance is important to maintain performance. Check the following
points to help maintain performance.
• Check that connectors on the rear panel are firmly tightened and free of rust.
• Check that the ground system is free of rust and the ground wire is tightly fastened.
• Check that battery terminals are clean and free of rust.
• Dust or dirt may be removed from the cabinet with soft cloth. Water-diluted mild de-
tergent may be used if desired. DO NOT use chemical cleaners to clean the display
unit; they may remove paint and markings.
• Wipe the display carefully to prevent scratching, using tissue paper and a display
cleaner. To remove dirt or salt deposits, use a display 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 display. 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 display.
7.2 Fuse Replacement
Junction box GS-1003
The junction box GS-1003 has a fuse that protects the GS-1003 from overcurrent and
equipment fault. If you cannot turn on the power, check the fuse to see if it has blown.
Find the reason for the blown fuse before you replace the fuse. If the fuse blows again
NOTICE
Do not apply paint, anti-corrosive sealant
or contact spray to plastic parts or
equipment coating.
Those items contain products that can
damage plastic parts and equipment coating.
WARNING
Use the proper fuse.
A wrong fuse can damage the equipment
and cause fire.
