CHARGING THE HEADSET

Connect the USB-C charging cable into the headset's USB-C charging port. If the headset is not fully charged, the indicator will turn red. When the indicator turns blue and stays blue, the unit is fully charged.
A fully discharged battery will need approximately 3 hours to achieve a complete charge.

Battery Power Indicators

While charging, the MFB's indicator light shows the level of battery power on your B450-XT MS as follows:

Blue light: Fully charged. Over 24 hours' talk time.
Red light: Less than a full charge.

Operation While Using the Charger/Adapter

The B450-XT MS 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 MS 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.

HOW TO WEAR AND ADJUST THE B450-XT MS

Adjusting the headband length
For a more comfortable and secure fit, the headband length can be adjusted as illustrated below:

Adjusting the headband tension
If the headband feels too tight or too loose, it is possible to adjust the tension of the headband for a more comfortable fit.
To adjust the tension of the headband, grip and flex it ONLY as shown in the diagrams below. Flex inward to increase tension. Flex outward to reduce the tension.
Use mild to moderate force when flexing the headband. Repeat the process until desired tension comfort level is attained.

Positioning the microphone
To get the best performance from our noise-canceling technology, position the microphone near the corner of your mouth. Positioning is important; small adjustments in microphone placement can improve performance.

1. Place the headset on your head.
2. Position the speaker directly on your ear. You can slide the headband in or out of the side support to find the best fit for stability and comfort.
3. Position the microphone about one finger's width away from your face at the corner of your mouth. The boom will rotate so you can position the microphone correctly with the speaker on either ear.
   

Switching microphone boom between left and right ear
The microphone boom can be adjusted for use on the right or left ear by sweeping it from one side to the other on the top side just underneath the headband. Do not try and push the microphone boom arm from one side to the other at the bottom of the headset.
