Maintenance
■
Clean dirt by wiping lightly with a soft cloth
When the unit is dirty, wipe the surface of the display using
the Wiping Cloth (supplied).
■
Without a Wiping Cloth
When the unit is dirty, wipe with a well-wrung cloth dipped
in liquid dish washing detergent (neutral) diluted with water
and then go over the same surface with a dry cloth.
(Since there is the possibility of water drops getting inside
of the unit, do not directly apply cleanser to the surface.)
Note:
Do not scratch the screen with your nails or other
hard objects. The resulting scratches or marks will obscure
the images.
Cautions:
¡
If water drops or similar wet substances get inside
the monitor, it may cause a malfunction.
¡
Never use solvents such as benzine, thinner as they
may mar the surface of the unit.
Caution:
Be sure to hold the
lower part of the monitor with both
hands and move it slowly without
applying undue force.
Notes:
¡
Refer to
“To Remove the Unit”
as well.
