To protect your hearing, follow these guidelines when you use headphones:

• Do not listen at extremely high volume levels. Extended high-volume listening can lead to permanent hearing loss.

• Set the volume to the lowest setting before you begin listening. Then, adjust the volume to a comfortable level.

After you set the volume, do not increase it.

• Do not wear headphones while operating a motor vehicle or riding a bicycle. This can create a traffic hazard and is

illegal in some areas.

listening and traffic safety

Your headphones and dongle are each powered by a built-in NiMH rechargeable battery, which you can
charge with the supplied 1-to-2 charging hub.

• The LED on the charging hub lights amber during charging and changes to green when the
headphones and dongle are fully charged.

• To optimize rechargeable battery life, discharge all power in the batteries before recharging

your headphones and dongle.

charging the headphones and dongle

• Keep your headphones within 32 feet (about 10 meters) within sight of the dongle. To avoid
interference, use only one set of headphones within the active dongle’s operating range.

• If the headphone or dongle LED do not light up when turned on, recharge the batteries.

• Use only one headphone with one dongle.
