3.1 Preventive Maintenance
Regular maintenance is important for good performance. A maintenance
program should be established and should include the following points.
• Check connectors and ground terminal on the processor unit and display unit
for tightness.
• Check ground terminal for rust. Clean or replace as necessary.
• Check for water leakage in the antenna cable. Replace the cable if there are
signs of water leakage.
• Remove dust and dirt from the display unit and processor unit with a dry, soft
cloth. For the LCD, wipe it carefully to prevent scratching, using tissue paper
and an LCD cleaner. To remove stubborn dirt, use an LCD cleaner, wiping
slowly with tissue paper so as to dissolve the dirt. Change paper frequently so
the dirt will not scratch the LCD. Do not use chemical cleaners for cleaning -
they can remove paint and markings.
