Listening Safely
Do not wear headphones, earphones, or earbuds while
operating a motor vehicle or riding a bicycle. This can
create a traffic hazard and could be illegal in some areas.
To protect your hearing, follow these guidelines:
Do not listen at high volume levels. Extended high-
volume listening can lead to permanent hearing loss.
Set the volume to the lowest setting. Then turn
on your audio device and adjust the volume to a
comfortable level.
Avoid increasing the volume. Your ears will adapt
to the volume level, so a level that does not cause
discomfort could still damage your hearing.
