Cleaning the Telephone
The telephone may occasionally need to be cleaned to maintain its appearance. Generally, wiping the surface with a
clean, water-dampened cloth will remove most films or residues. If the soiling is too stubborn for plain water, a mild
detergent solution may be used. Wipe away any detergent residue with a plain water dampened cloth. The telephone
may be cleaned with any general-purpose household glass and surface type cleaner. Do not spray the telephone
directly! Spray the cleaner on a soft cloth and then wipe the surface. Pretreated cloths, like those used for eyeglasses
or cameras, may be used to clean the telephone. Pre-moistened towelettes may also be used; however, avoid those
containing lanolin or aloe, as they will leave a slippery residue. The handset and surface of the telephone may be
cleaned with disinfectants used for general cleaning in a medical environment. Isopropyl alcohol may be used applied
with a cloth. Avoid using alcohol on silicon-based keypads, since doing so may significantly degrade legibility.

If the area is air conditioned and not subject to high changes in humidity, continue to store the unit in its original
packaging.
•
If wide humidity shifts are expected, then follow these steps:
•
Remove the product from its packaging (including plastic bags) and store it on a shelf in open air.
• If the area is subject to a high degree of dust, to help maintain the cosmetic appearance, you can cover it with
a cloth (do not cover the unit with plastic or materials that will trap moisture) or clean periodically.
• Do not store the unit out of its packaging long term where it would be are exposed to sunlight. Long-term
exposure to UV may cause fading.
