BEFORE YOU BEGIN Select one of the four earbuds and insert it into the receiver, aligning the pins with the notches. Rotate the earbud clockwise, 1⁄4 turn, until it clicks into place. Try all four earbuds until you find one that comfortably rests against, but does not enter, your ear canal. WARNING For your safety and comfort, the earpieces should not be inserted into the ear canal. Never remove the black retention ring from the base of the earpiece or use an earpiece without the retention ring in place. This headset is not intended for children under the age of 14 and can be dangerous and harmful to younger children. Some parts of this headset are small enough to be swallowed or to become lodged in a child's windpipe, ears or nose. In addition, this headset, as with any product with long strings or cords, may be dangerous for infants and young children as the cords may become wrapped around a child's neck, causing strangulation. To avoid danger of suffocation, keep the plastic bags in which this product is wrapped away from babies and children. Do not use the bags in cribs, beds, carriages or playpens. The plastic bags could block the nose and mouth and prevent breathing. english
