Operation
Receiving calls
Calls received are indicated with acoustic signals of the built-in speaker.
If the external speaker is connected and activated, the external speaker
is used for acoustic signalling. Lift the handset to establish the
connection with the caller. For activating the hands-free mode or
headset mode press the speaker button instead.
Making a call
Lift the handset, and you can hear the dial tone (dial ready tone) of the
public network or of the PBX network respectively.
Press the speed dialling button or the redial button or use the numeric
keys to select the phone number of the other party automatically or
manually.
Instead of lifting the handset, you can press the speaker button to make
a call in open conversation or headset mode.
For selecting a new phone number, you do not need to place the
handset back, you can press the disconnect button. The present
conversation is ended and you can hear the dial tone to select a new
phone number.
Redialling
If you press the redial button, the phone selects the last phone number
dialled after lifting the handset or pressing the speaker button.
Making a second call
During the conversation, you can disconnect and place the present
conversation on hold to make a second call with a different party. Press
the second call button and you will hear the dial tone. Dial the phone
number of the second party. After ending the second call, you can return
to the first call on hold by pressing the second call button again. You
can also connect the two parties of the first and second call with each
other: Place the handset back or press the speaker button in hands-free
or headset mode.
Making a second call is an additional service of the network operator or
of the PBX you use.
Operation with active phone lock
In case of active phone lock the dialling is limited or completely blocked.
If the blocked keys are still pressed, the phone generates the signal
“error tone”.
