Cleaning the Touch Screen
1
Wipe only the LCD area with a soft cloth moistened with neutral detergent or alcohol.
NOTE:
•
When you moisten the cloth with neutral detergent or alcohol, do not allow the excess liquid
to drip down from the cloth. If the cloth is moistened with the excess liquid, wring the cloth
gently before wiping the LCD area.
•
Do not use any volatile liquids on the machine such as benzene and paint thinner, or insect
repellent as these may discolor, deform, or crack the machine exterior.
•
Cleaning the touch screen with an excessive force may cause the screen to be damaged. Wipe
the screen gently.
