Hearing safety
Caution
•
To avoid hearing damage, limit the time you use the
headphones at high volume and set the volume to a
safe level. The louder the volume, the shorter is the safe
listening time.
Be sure to observe the following guidelines
when using your headphones.
• Listen at reasonable volumes for
reasonable periods of time.
• Be careful not to adjust the volume 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 temporarily
discontinue use in potentially hazardous
situations.
• Excessive sound pressure from earphones
and headphones can cause hearing loss.
