• Screen Cleaning
Periodically clean the screen surface using non-abrasive, ammonia-free cleaning wipes.
A clean micro
fi
ber cloth can also be used. Do not use paper towels. Paper towel
fi
bers are
coarse and may scratch the surface of the polycarbonate faceplate or leave streaks on the
surface. Antistatic and
fi
ngerprint resistant cleaning agents are recommended. Do not apply
excessive pressure to the screen to avoid damaging the LCD.
• Faceplate Dusting
Dust the unit with a soft cloth or chamois. You may use a slightly damp cloth, but make sure
unit is not connected to any power. Dry or abrasive cloths may cause electrostatic charge on
the surface,attracting dust particles. Neutralize static electricity by using the recommended
cleaning and polishing practice.
