Cleaning the Touchscreen
Touchscreens can be effectively cleaned with water or up to 70% isopropyl alcohol
solution. Follow these steps to avoid damage to the touchscreen:
Warning: Do not use sharp objects to clean around the edges of the touchscreen. Do
not use abrasive cleaners (powders) or abrasive cleaning materials (scrub brush,
scouring pad).
Warning: Do not use Windex or any similar alkaline (weak base)cleaner as it can
degrade the anti-glare coating.
1. Clean the screen using a non-abrasive cloth (microfiber cleaning cloth or cloth towel)
and water.
Warning: Do not apply any cleaning products directly to the screen. Do not soak
the cloth: wring it out before use.
2. Dry the screen with another soft cloth.
3. Clean the screen further using a cloth dampened with isopropyl alcohol solution, or
using pre-packaged wipes.
Warning: Do not apply any cleaning products directly to the screen. Do not soak
the cloth: wring it out before use.
4. Ensure that the glass and screen edges are completely dry before using the unit.
