9. MAINTENANCE & TROUBLESHOOTING
9-2
9.2 Preventive
Maintenance
Regular maintenance is necessary to
maintain performance. Check the items
mentioned below monthly to keep the
equipment in good working order.
NOTICE
Do not apply paint, anti-corrosive sealant or
contact spray to coating or plastic parts of
the equipment.
Those items contain organic solvents that can
damage coating and plastic parts, especially
plastic connectors.
For the LCD screen, 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. Also, do not use
degreaser or antifog solution, as they can
strip the coating from the LCD.
Antenna unit
Check fixing bolts for tightness.
Antenna cable
Check connector for tightness, rust, damage
and water leaks.
Power cable
Check for tight connection.
Ground terminal
Check for rust and tight connection.
Fuse
The 2A fuse (Type: FGBO-A 2A AC125V,
Code No.: 000-549-062) in the power cable
protects the unit from overvoltage and
equipment fault. If the fuse blows, find out
the cause before replacing the fuse. If the
fuse blows after replacement, request
service.
WARNING
Use only a 2A fuse in the power cable.
Use of different fuses may cause fire.
Battery
A battery installed on the NP board inside
the display unit preserves date when the
power is turned off. The life of the battery is
about three years. When the battery voltage
is low “NG” appears on the start-up display.
When this happens, contact your dealer to
request replacement of the battery.
