If the headset is paired to both, the IP Phone is the second device. When
you press the headset telephone key and you hear a single tone, the
headset is active for a call from the desktop IP Phone base.
To use the headset with the IP Phone, press and hold the headset telephone
key for 1 second. You hear a double beep. The headset is active with the IP
Phone.
If the base is powered off, the headset is only paired to the IP Phone. Press
the headset telephone key to connect to the IP Phone.
Unless a need exists to dual-pair a headset, the operation of the headset
with the IP Phone is simpler if the headset is only used with its charging-only
base. The desktop IP Phone base should be powered off if it is not in use.
Interaction with wired headsets
If you connect a Bluetooth wireless technology headset and a wired handset
to the same IP Phone, the two interact as follows
•
•
The Bluetooth wireless technology headset can work only within range
of the IP Phone; as a wireless headset approaches the edge of its radio
range, the audio quality degrades and radio interference noise increases.
When the wireless headset is in connecting range, the Headset key controls
the headset, even if a wired headset is attached. If a Bluetooth wireless
technology headset moves out of connecting range, a special beep sounds
in the headset to indicate that the connection is lost.
When you do not want to use Bluetooth wireless technology
If a Bluetooth wireless technology headset is connected, and you want
to use the wired headset, you can switch between the wireless headset
and the wired headset. It is not necessary to unpair or disable Bluetooth
wireless technology. You can switch between a wired headset and back
again when the phone is idle or during an active call.
