11.7NBDP Terminal Unit Maintenance

Regular maintenance is important for good performance. A regular maintenance program should be established and should at least include the items mentioned below.

11.7.1Cleaning the equipment

Wipe off accumulated dust from the terminal unit with a soft cloth. 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 surface of LCD. Do not use solvents such as thinner, acetone or benzene for cleaning; they can remove paint and marks or deform the equipment.

11.7.2Connectors and earth connection

Periodically check the connectors for proper seating and the earth connection for rust. Remove rust to maintain a good ground system.

11.7.3Floppy disk drive

Foreign material on the floppy disk drive head can scratch the magnetic material in the floppy, resulting in loss of data. Clean the floppy disk drive head regularly with a floppy disk drive cleaning disk to prevent erasure of information stored on disks.
