Fixing Problems

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

Æ Page 71.

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 Æ Page 75.

To correct any other problem:

First contact your service personnel. If your service personnel is unable to

correct the problem, contact Customer Service.
