Listening Cautions                 
z 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 at high volumes and it seems 
normal to you, you still risk the possibility of damaging your hearing. Reduce the 
volume of your device to a reasonable level 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 with 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 that respect the 
current regulations. Other types of headphones may produce higher volume 
levels.(At full power ,the prolonged listening of the walkman can damage the ear 
of the 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 created by obstructed hearing. 
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 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 without distortion. Once you have established a comfortable sound 
level, leave it there. 
This manual may not reflect your actual device’s operation. All information is subject to change 
without prior notification. Please follow your actual device’s operational procedures.
