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

Check if the key is stuck.
The phone does not ring on call:
Check whether the ringtone is deactivated (see icon in the status bar on the display
Page 94).
If it is deactivated, activate the ringtone
You cannot dial a number:
Check whether your telephone is locked ("Phone locked. To unlock enter the PIN" appears on the
screen). If the phone is locked, unlock it.

tact Customer Service.
