Maintenance

■

Screen Cleaning

Periodically clean the screen surface using ammonia-free cleaning wipes (Marshall Part No. V-HWP-K). A clean micro-

fiber cloth can also be used using only non-abrasive and ammonia-free cleaning agents. Do not use paper towels.

Paper towel fibers are coarse and may scratch the surface of the polycarbonate faceplate or leave streaks on the

surface. Antistatic and fingerprint 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, damp cloth or chamois. Dry or abrasive cloths may cause electrostatic charge on the surface,

attracting dust particles. Neutralize static electricity effects by using the recommended cleaning and polishing practice.
