5.1 Maintenance
Routine maintenance
Regular maintenance is important for good performance. Check the following on a regular
basis to keep the equipment in good operating condition.
• Check that the connectors at the rear of the display unit are tightly fastened.
• Check the ground wire and ground terminal for rust. Clean if necessary. Confirm that the
ground wire is tightly fastened.
• Dust or dirt may be removed from the cabinet with soft cloth. Water-diluted mild
detergent may be used if desired. DO NOT use chemical cleaners to clean the display
unit; they may remove paint and markings. 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. Also, do not use degreaser or antifog solution,
as they can strip the coating from the LCD.
Fuse replacement
The fuse (Type: FGMB 250V 2A PBF, Code No.: 000-157-497-10) on the rear panel
protects the equipment from overcurrent. If the equipment can not be powered, contact your
dealer for advice.
WARNING
Use the proper fuse.
Use of a wrong fuse can cause fire or
damage to the equipment.
