Listening Cautions
z Do not play your earphones or headphones at a high volume. Hearing experts
advise against continuous extended play.
z If you experience a ringing in your ears, reduce volume or discontinue use.
z Do not use while operating a motorized vehicle. It may create a traffic hazard
and is illegal in many areas.
z You should use extreme caution or temporarily discontinue use in potentially
hazardous situations.
z Even if your headphones or earphones are the open-air type designed to let
you hear outside sounds, don’t turn up the volume so high that you can’t hear
what’s around you.
z Sound can be deceiving. Over time you hearing “comfort level” adapts to
higher volumes of sound. So what sounds “normal” can actually be loud and
harmful to your hearing. Guard against this by setting your equipment at a safe
level BEFORE your hearing adapts.
To establish a safe level:
a. Start your volume control at a low setting.
b. Slowly increase the sound until you can hear it comfortably and clearly,
and without distortion. Once you have established a comfortable
sound level, leave it there.
