Telephone Maintenance
• Always use a damp or antistatic cloth to clean the telephone. Never
use a dry cloth.
• If the telephone is very dirty, clean it with a diluted neutral cleaner con-
taining surfactants, such as a dish detergent. Afterwards remove all
traces of the cleaner with a damp cloth (using water only).
• Never use cleaners containing alcohol, cleaners that corrode plastic, or
abrasive powders.
Echo Effect
Echoes can occur - sometimes quite distinctly - in the course of a tele-
phone call. This effect is not caused by a product or design fault in your
telephone but rather by the other party's telephone.
Troubleshooting
Pressed key does not respond:
Check whether the key is stuck.
Telephone does not ring:
Check whether the do not disturb function was activated on your tele-
phone (" Do not disturb" appears on the screen). If so, deactivate it
! Page 76.
You cannot dial an external number:
Check whether you telephone is locked ("US:Not authorized UK:Access
denied" appears on the screen). If so, unlock the telephone ! Page 80.
To correct any other problem:
First contact your service personnel. If your service personnel is unable to
correct the problem, contact Customer Service.
