Problem

Solution

My headset does not work 
with the internet calling ap-
plication I am using on my PC. 
(I cannot answer or disconnect 
from the headset call button).

Check compatibility list on www.plantronics.com/personocall to 
ensure your internet calling application is compatible for remote 
answer and  
disconnect.

Headset battery needs to be charged. See page 5.

Headset is not paired to the USB 

Bluetooth

 adapter. See page 7.

When a PC goes into standby or hibernation, the USB 

Bluetooth

adapter no longer is powered on. Be sure your PC is in an active 
state.

Be sure PerSonoCall software is installed 
and running. See page 9.

I’ve plugged in the USB Blue-
tooth adapter but my headset 
does not respond to button 
presses

Bluetooth

 adapter. Move 

closer to adapter until the headset is within range. Range varies 
with office environment.

I’ve installed PerSonoCall and 
the USB Bluetooth adapter but 
the system tray icon shows a 
red X (denoting no connection).

The USB 

Bluetooth

 adapter is not set as the default audio device. 

Use the Audio settings in Windows® under Sounds and Audio De-
vices to select “Plantronics BT Adapter” as the audio device.

Listening volume is too low. Press the volume up button on the 
headset. See page 11

Headset is muted. Press the mute button on headset to unmute the 
microphone.

Headset microphone boom aligned incorrectly. Align the headset

the Voice settings in Windows® under Sounds and Voice Devices to 
select “Plantronics BT Adapter” as the voice device.

Sound in headset is distorted. I 
can hear echo in headset.

Lower the listen volume on your internet calling application until the 
distortion disappears.

Adjust volume on headset. See page 11.

The other headset I was using 
to listen to music does not work 
any more.

The USB 

Bluetooth

 adapter will set itself as the default audio device 

in Windows®. Use the Audio settings in Windows® under Sounds
