Cleaning your WLAN Handset
The WLAN Handset occasionally must be cleaned to maintain appearance. In general, wiping the

If more rigorous cleaning is required, you can use:

Spray the cleaner on a soft cloth or paper towel, then wipe the handset.

• 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

• 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.
