which is in compliance with the
EU Noise Directive

Pairing the headset
Upon delivery, the headset and the base
station are pre-paired together. You can
pair the headset to:
• a mobile phone
• or a similar device with a Bluetooth
“handsfree” or “headset” profile
Once you have paired and connected to
a Bluetooth device, the headset will
remember this setting and automati-
cally try to connect to the last used
device every time you open the boom
arm.
• If last connected to a base station, the
headset will try to connect to a base
station when the boom arm is opened
the next time.
• After a firmware update, the headset
will automatically connect to a base
station.
