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 IP65 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 140° F or 60° C (will cause equipment failure).

CHARGING THE HEADSET (continued)
Operation While Using the Charger/Adapter
The C300-XT MS headset will operate from battery power or from power supplied via
the USB cable.
NOTE: Do not attach the USB cable to a powered USB 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 LEDs and sounds will
function as described in this guide.
When the headset is operating from power supplied via the USB cable, the headset—
including the audio indicators—will function as described in this user guide. However,
the MFB LED 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 LED will change from red to blue and stay
blue as long as a powered USB cable is connected to the headset.
