The WLAN Handset occasionally must be cleaned to maintain appearance. In general, wiping the
handset surface with a clean water-dampened cloth or paper towel removes most films or residues.

If more rigorous cleaning is required, you can use:

•

A mild detergent solution. Be sure to wipe away any detergent residue with a plain
water-dampened cloth.

•

Any general-purpose household glass and surface cleaner. Do not spray the handset directly.
Spray the cleaner on a soft cloth or paper towel, then wipe the handset.

•

Pre-treated cloths, like those used for eyeglasses or cameras.

•

Pre-moistened towelettes. Avoid those containing lanolin or aloe, which leave a slippery
residue.

•

Isopropyl alcohol, applied by a damp cloth or paper towel. When using alcohol, do not rub the
keypad characters vigorously, as this will significantly degrade legibility.

If the headset connector becomes dirty, you may experience a scratchy or intermittent signal. To
clean the connector, dip the padded end of either a wooden- or paper-handled cotton swab in
isopropyl alcohol. Gently insert in the connector and twist, repeating several times. If available,
blow compressed air into the connector to clear debris.

IMPORTANT!

•

Do not use furniture polishes, waxes, or plasticizer-based cleaner.

•

Do not use lanolin, aloe, glycerin, or other skin care products.

•

Do not apply any solvent such as acetone or mineral spirits.

•

Do not directly spray or immerse the handset.
