Fixing problems
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 cleaners containing alcohol, cleaners that corrode plastic or abrasive powders!
Troubleshooting
Pressed key does not respond:
• Check if the key is stuck.
• If the phone is locked, selected dialing keys cannot be used. This also applies even if an emer-
gency number is saved on this key.
Check whether your telephone is locked (The following message appears on the screen: "Phone
locked. To unlock, enter the PIN."). If the phone is locked, enter your PIN to unlock it.

locked. To unlock, enter the PIN.
"). If the phone is locked, enter your PIN to unlock it.

solved.
