IPrecautions for Listening

with the Headphones

000 not play your headset at a high
volume. Hearing experts advise against
continuous extended play.

Ilf you experience a ringing in your ears,
reduce volume or discontinue use.

000 not use while operating a motorized
vehicle. It may create a traffic hazard and
is illegal in many areas.

IYou' should use extreme caution or tem-
porarily discontinue use in potentially haz-
ardous situations.

uEven if your headset is an open-air type
designed to let you hear outside sounds,
don't turn up the volume so high that you
cant hear what's around you.
