Volume Adjustment/Mute Switch
Fig 8
If you are using an M12 or

variable volume control. Start
with setting 4, then increase
or decrease the setting until
you reach a comfortable
listening volume.
You can prevent a caller
from hearing your voice by
pressing the mute switch on
the adapter. Voice contact
can be retrieved by pressing
the switch again.
If you use an adapter please
refer to the adapter user
guide.
If you do not have an
adapter these features will
be controlled by your
telephone system. Please
refer to the appropriate user
guide.
Hook Switch Control
Fig 9
For certain DECT
applications, the headset
can be supplied with a hook
switch control in line on the
cable. You can use this
switch to answer or end
a call.
Clothing Clip
Fig 10 The clothing clip keeps the
headset properly positioned
by supporting the weight of
the cord. Attach the clothing
clip comfortably at chest
height, making sure there is
enough slack to allow for
head movement.
Quick Disconnect Connector
Fig 11 Some models are fitted with
a Quick Disconnect
connector. Before you use
your headset, join the
adapter cable and the Quick
Disconnect together.
When you separate the
Quick Disconnect, you put
your telephone conversation
‘on hold’ without removing
the headset.
To do this, hold the Quick
Disconnect as shown and
pull straight apart. To
resume the call, reconnect
the two halves.
