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.

Care and Maintenance
• Keep the headset dry. If it gets wet,
wipe it dry immediately.
• Use and store the headset in room
temperature environments.
• Handle the headset carefully; do not
drop it.
• Keep the headset away from dust and
dirt, and wipe it with a damp cloth
occasionally to keep it looking new.
