kept clear.
The optimum distance is approx. 50 cm.

inating light reflexes.

Single-line telephone/multi-line telephone
Your OpenScape Desk Phone IP is a "multi-line telephone" . This means that multiple lines can be
configured, 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 sensor keys are configured as line keys on multi-line phones
The "Overview" tab on the telephony interface provides information about the lines configured on
your phone and the current status of each line
When using a multi-line phone to make and receive calls, certain particularities must be taken into
account
