Step by Step

Troubleshooting

Pressed key does not respond

Check if the key is stuck.

Telephone does not ring

Check whether the "Do not disturb" function is activated

on your telephone ("Do not disturb" appears on the

screen Æ page 21). If so, deactivate it Æ page 77.

You cannot dial an external number

Check whether you telephone is locked ("Not authori-

zed" appears on the screen). If the phone is locked, en-

ter your PIN to unlock it Æ page 80.

To correct any other problems

First contact the relevant service personnel. If the ser-

vice personnel are unable to correct the problem, they

must contact Customer Service.

Caring for your telephone

• Never allow the telephone to come into contact

with coloring, oily or aggressive agents.

• 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 containing surfactants, such as a

dish detergent. Afterwards remove all traces of the

cleaner with a damp cloth (using water only).

• Never use aggressive or alcohol-based cleansers on

plastic parts. The use of scouring agents is also for-

bidden.
