Listening Cautions

 This product respects the current regulations for limiting the output volume of

consumer audio devices to a safe level. By listening to your device with
headphones or earbuds at high volumes, you run the risk of permanent damage
to your ears. Even if you get used to listening a t high volumes and it seems
normal to yo u, y ou s t il l ri sk t he po ss ib i li t y of d am agi n g yo ur he a rin g. R edu c e the
volume of yo ur device to a reasonable lev el to avoid permanent hearing damage.
If you hear ringing in your ears, reduce the volume or shut off your device. This
device has been tested wit h the supplied earphones. In order to preserve your
hearing, it is advised that you use only the following headphone models: the
earphones supplied with your device, or any other headphones t hat respe ct the
current regulations. Other types of headphones may produce higher volume
levels.（At full power ,the prolo nged li stening o f the w alkman can da mage the ea r
of the use）

 Do not use while operating a motorized vehicle. It may create a traff ic hazard

and is illegal in many areas.

 You should use extreme caution or temporarily discontinue use in potentially

hazardous situations created by obstructed hearing.

 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.

 Sound can be deceiving. Over time your hearing “comfort level” adapts to higher

volumes of sound. What sounds “normal” can actually be loud and harmful to
your hearing. Guard against this by setting the volume of your device at a safe
level BEFORE your hearing adapts.

To establish a safe volume level:

a. Start your volume control at a low setting.
b. Slowly increase the sound until you can hear it comfortably and clearly,

and witho ut distortion. Once you have establ ished a comfortabl e sound
level, l eave it there.
