you tried to program a station number without LED display or an external station
number on a key that already is already programmed with an internal phone
number with LED display.
Possible reactions:

station number remains on the other layer without LED display.

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
page 23). If so, deactivate it.
You cannot dial an external number:
Check whether you telephone is locked ("Not authorized" appears on the
screen). If the phone is locked, enter your PIN to unlock it
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 aggres-
sive 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 forbidden.
