Service
If you experience problems or defects with the phone, please dial the service
number for your country.
Intended use
The OpenScape Desk Phone has been developed as a device for speech trans-
mission and should be placed on the desk. Any other use is regarded as unau-
thorized.
Telephone type
The identification details (exact product designation and serial number) of your
telephone can be found on the underside of the base unit. Specific details con-
cerning your communication platform can be obtained from your administrator.
Please have this information ready when you contact the service department re-
garding faults or problems with the product.
Speakerphone quality and display legibility
• To ensure good speakerphone quality, the area in front of the telephone (front
right) should be kept clear.
The optimum handsfree distance is approx. 50 cm.
• Proceed as follows to optimize display legibility:
– Turn the phone to tilt the display to ensure you have a frontal view of the
display and avoid light reflections.
– Adjust the contrast as required
Single-line telephone/multi-line telephone
Your OpenScape Desk Phone CP400T is a "multi-line telephone". This means
that your service personnel can configure multiple lines on your phone, which is
not the case with single-line phones. Each line is assigned an individual phone
number which you can use to make and receive calls.
The programmable keys function as line keys on multi-line phones
When using a multi-line phone to make and receive calls, certain particulars
must be taken into account
The executive-secretary configuration is a special case. This is a multi-line tele-
phone with special features (e.g., "Ring Transfer" and "Accept call"), configured
especially for executive/secretary use
The service department can only help you if you experience problems or
defects with the phone itself.
Should you have any questions regarding operation, your specialist re-
tailer or network administrator will be glad to assist you.
