4.1 Maintenance
Routine maintenance
Regular maintenance is important for good performance. Check the following on a regular basis
to keep the equipment in good condition.
• Check that the connectors at the bottom 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.
• Remove dust and dirt from the display unit with a dry, soft cloth. Do not use chemical cleaners
to clean any part of the display unit. They can remove paint and markings.
• Wipe the LCD carefully to prevent scratching, using LCD cleaning cloth (supplied as
accessory). 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 in the fuse holder on the power cable protects
the equipment from internal fault. If the fuse blows, find
the cause before you replace it. If the fuse blows again af-
ter replacement, request service.
