Care of the telephone
•
To clean the telephone, use a slightly damp cloth or
an antistatic cloth. Never wipe the phone with a dry
cloth!
•
If necessary, you may use a diluted mild detergent
(commercially available). After cleaning, thoroughly
remove the detergent using a cloth dampened with
water.
•
Do not use alcohol-based detergents or any abra-
sive cleaning products.
