9.7 Cleaning

For cleaning of the device consider the following instructions:

• Use a soft, lint-free cloth (for example, soft cotton or microfiber cloth). Do not use paper towels or

paper tissues (they contain wood fibers and will scratch the plastic surface).

• The cloth may be used dry, or lightly dampened (not wet) with water.

• Wipe the surface gently, do not use excessive force.

• If needed, a mild and pH neutral cleaner can be used.

• Do not use acidic/alkaline cleaners or organic chemicals such as paint thinner, acetone, toluene,

xylene, propyl alcohol, isopropyl alcohol, or kerosene.

• Do not apply a cleaner directly to touch panel or any other surface. In case a cleaner is spilled onto

the device soak it up immediately with absorbent cloth.

Use of inappropriate cleaners or cleaning methods can result in optical degradation of the touchscreen/pro-

tection glass and/or affect its functionality.
