• 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.
To establish a safe volume level:
• Set your volume control at a low setting.
• Slowly increase the sound until you can hear it comfortably and
clearly, without distortion.
Listen for reasonable periods of time:
• 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.
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 poten-
tially hazardous situations.
• Do not use headphones while operating a motorized vehicle,
cycling, skateboarding, etc.; it may create a traffic hazard and is
illegal in many areas.
• Important (for models with by-packed headphones): Philips
guarantees compliance with the maximum sound power of its
audio players as determined by relevant regulatory bodies only
with the original model of provided headphones. In case this
one needs replacement, we recommend that you contact your
retailer to order a model identical to that of the original
provided by Philips.
• Traffic safety: do not use while driving or cycling as you may
cause an accident.
