Fixing problems
Caring for your telephone
• Never allow the telephone to come into contact with colouring, 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 cleaning fluids containing alcohol or plastic-damaging detergents to clean the tele-
phone. The use of scouring agents is also forbidden.
Troubleshooting
Pressed key does not respond:
• Check if the key is stuck.
• If the telephone is locked repdial keys cannot be used. This also applies when an emergency
number is saved on it.
Check whether your telephone is locked ("Phone locked. To unlock enter the PIN" appears on the
screen). If the phone is locked, unlock it.
