When you pair your headset to your Bluetooth phone,
you are creating a private link between only these two
Bluetooth devices. The wireless Bluetooth technology
used in your headset is not easily monitored by third
parties because Bluetooth wireless signals are significantly
lower in radio frequency power than those produced
by a typical mobile phone.
Adjust the headset volume, or move to another area
and try again.
Wipe it with a soft dry cloth.
The headset and the travel adapter may not have
been connected properly.
Separate the headset from the travel adapter,
reconnect, and charge the headset.
