SAFETY INFORMATION
IMPORTANT SAFETY NOTE: Prolonged exposure to high volume levels can damage your
hearing. To avoid injury, set the volume to the lowest comfortable level. If you experience
ringing in your ears, or voices sound muffled, stop using the headset. Avoid turning up the
volume to block noisy surroundings. It’s possible for your ears to adapt to volume that
is too high, and this could result in permanent hearing damage without any noticeable
discomfort.
• Check with local and state laws regarding cell phone/headset usage while operating a
motor vehicle.
• The headset is IP54 rated. Do not immerse any part of this product in water.
• Plastic bags and small parts may cause choking if ingested. Keep them away from small
children and pets.
• Use only the power cords included with this product.
• Avoid temperatures exceeding 60° C (140° F) (may cause equipment failure).

CHARGING THE HEADSET (continued)
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.
