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.
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 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.

Fuse replacement

The 3 A 250 V fuse on the rear panel protects the equipment from internal fault and
overvoltage. If the fuse blows, find the cause before replacing it. If the fuse blows again
after replacement, request service.
