PREPARATION

Listening Safely

To protect your hearing, follow these guidelines when you use headphones.
Set the volume to zero before putting on headphones. With the headphones on,
adjust the volume to a comfortable level.
Avoid increasing the volume once you set it. Over time, your sensitivity to a volume
level decreases, so volume levels that do not cause discomfort might damage your
hearing.
Avoid or limit listening at high volume levels. Prolonged exposure to high volume
levels can cause permanent hearing loss.

Traffic Safety

Wearing headphones while operating a motor vehicle or riding a bicycle can create a
traffic hazard and is illegal in most areas.
Even though some headphones let you hear some outside sounds when listening at
normal volume levels, they still can present a traffic hazard. Exercise extreme caution!
