Hearing Safety
Danger
To avoid hearing damage, limit the time you
use headphones at high volume and set the
volume to a safe level. The louder the
volume, the shorter the safe listening time is.
Be sure to observe the following guide-
lines when using your headset.
• Listen at reasonable volumes for
reasonable periods of time.
• Be careful not to adjust the volume
continuously upwards as your
hearing adapts.
• Do not turn up the volume so high
that you can't hear what's around
you.
• You should use caution or tempo-
rarily discontinue use in potentially
hazardous situations.
• Excessive sound pressure from
earphones and headphones can
cause hearing loss.
• Using headphones with both ears
covered while driving is not recom-
mended and may be illegal in some
areas while driving.
• For your safety, avoid distractions
from music or phone calls while in
trac or other potentially dangerous
environments.
