Maintenance

• Clean the cabinet and protection panel by gently wiping it with a soft cloth.
To remove stubborn soiling, use a cloth dampened in a weak neutral detergent solution and thoroughly wrung
out. Then wipe with a dry cloth. Any moisture entering the monitor could damage it.
• Do not use benzene, thinner and similar solvents for cleaning.
They could discolor the surface and cause the paint to peel.
• Do not directly expose the monitor to spray cleaning.
Any moisture entering the monitor could damage it.
Symptom
If a malfunction occurs in the inverter that
controls backlight brightness, the
backlight goes off and the screen turns
black.
A "LOW VOLTAGE" indication in blue
flashes on the screen.
This means that the external DC power
supply input voltage has dropped to
approximately 11.3 V or less.
The "LOW VOLTAGE" indication flashes
in red on the screen and the power is
turned off approximately 4 seconds later.
This means that the external DC power
supply input voltage has dropped below
11.0 V.
Remedy
Turn off the power and then turn it back
on. If the problem still persists, consult
your dealer.
• If you use a battery pack as an
external DC power supply, replace it
with a fully charged battery pack.
• Connect an external DC power supply
providing 11.0 V or more. Set the
POWER switch to the off position and
then set it to the on position again.
