Hearing safety
Listen at a moderate volume.
Using headphones at a high volume can impair your hearing. This ‡
product can produce sounds in decibel ranges that may cause hearing
loss for a normal person, even for exposure less than a minute. The
higher decibel ranges are offered for those that may have already
experienced some hearing loss.
Sound can be deceiving. Over time your hearing ‘comfort level’
‡
adapts to higher volumes of sound. So after prolonged listening, what
sounds ‘normal’ can actually be loud and harmful to your hearing. To
guard against this, set your volume to a safe level before your hearing
adapts and leave it there.
Set your volume control at a low setting.
‡
Slowly increase the sound until you can hear it comfortably and ‡
clearly, without distortion.
Prolonged exposure to sound, even at normally ‘safe’ levels, can also
‡
cause hearing loss.
Be sure to use your equipment reasonably and take appropriate
‡
breaks.
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. Do not use headphones while operating a

Caution
Use of controls or adjustments or performance of procedures other than herein
‡
may result in hazardous radiation exposure or other unsafe operation.
