12.9 NBDP 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. 
 
12.9.1 Cleaning the equipment 
Wipe of 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 LCD. Do not use solvents 
such as thinner, acetone or benzene for cleaning; they can remove paint and marks or 
deform the equipment.   
 
12.9.2 Connectors and earth connection 
Periodically check the connectors for proper seating and the earth connection for rust. 
Remove rust to maintain a good ground system. 
 
12.9.3 Floppy 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.
