Step by Step
Setting the speakerphone volume
The volume can be set during a call ( Æ Page 23).
Conducting calls with the headset
Gigaset M2 professional can be used with a corded and
cordless headset. Gigaset M2 Ex professional can
only be used with a cordless headset .
Corded headset
You can connect a corded headset via the jack on the
underside of the handset ( this does not apply to the
Gigaset M2 professional ). The headset must have a
Slim Lumberg connector.
The receiver inset and microphone functions are activat-
ed on the headset once it is connected.
Cordless headset
You can use a cordless, Bluetooth headset with your
handset. This means your hands are free while making
calls, and there are no annoying cables, for example,
when you are working at your computer or when you
are on the road.
Your Bluetooth headset must be registered on your
handset before you can use it for the first time. After
this, you can continue to use your Bluetooth headset
until you decide to de-register it.
Note:
If you wish to replace the handset in the charg-
ing shell during a call, for example, because the
battery pack is flat, hold down the Speaker-
phone key to prevent the call from being cleared
down.
Danger:
Only BT headsets with the appropriate Ex protec-
tion rating are permitted in potentially explosive
atmospheres.
