CHARGING THE HEADSET (continued)
Operation While Using the Charger/Adapter
The B450-XT headset will operate from battery power or from power supplied via the
USB-C cable.
NOTE: Do not attach the USB-C cable to a powered USB-C port mid-call. This will cause
the headset to reset, and the call will be sent back to the phone.
When the headset is operating from the battery, all indicator lights and sounds will
function as described in this guide.
When the headset is operating from power supplied via the USB-C cable, the headset—
including the audio indicators—will function as described in this user guide. However,
the MFB lights will indicate the battery charge status.
While the headset is on the charger, press the MFB long enough to power the unit on.
The headset should reconnect automatically unless your phone is set to “always ask” for
connection requests.
After the battery is fully charged, the MFB charge light will turn blue and stay blue
as long as a powered USB-C cable is connected to the headset. While the headset is
fully charged and the charge light is blue, the blue indicator light will also be on if the
headset is powered on.

GETTING STARTED
On/Off/Standby
Turn Headset On: Hold down the MFB for approximately 2-3 seconds until you
hear a voice prompt, “power on.” The red light will flash once every second.
Turn Headset Off (conserves battery power): Hold down the MFB for
approximately 4–5 seconds until you hear a voice prompt “power off.” A red light
will flash 4 times and the headset will turn off.
Standby Mode: Once the headset is turned on (after the initial pairing), it will
attempt to connect to the last device that it was paired with, putting itself into
Standby Mode.
Pairing with a Phone
When you turn your B450-XT on for the first time,
or if its Paired Device List has been cleared, it will
go into pairing mode automatically. You can pair
the headset using NFC or manually.
NFC (One-Touch) Pairing
1. Make sure that NFC is enabled on your cell
phone.
2. Place the NFC zone of your cell phone against
the NFC zone of the headset and hold them
together until your cell phone registers the
headset.
3. Follow the prompts on your cell phone to
complete pairing.
Note: NFC and One-Touch Pairing are dependent
on your cell phone. The size and sensitivity of your
phone’s NFC zone and the specific way to connect
the headset may vary between devices.
