Check whether your telephone is locked.
If the phone is locked, enter your PIN to unlock it Æ page 69.
To correct any other problems:
First contact the relevant service personnel. If the service 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 con-
taining 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 forbidden.
