Care and use
To reduce risk of radio interference caused by headphone-, earphone- or microphone cables, only use 
adequate accessories with a cable length of less than 3 m (9.8 ft.).
g Unit• 
Avoid using or placing this unit near sources of heat. 
•  
To avoid product damage, do not expose this product to rain, water or other liquids.
•  
The unit’s speaker does not have magnetic shielding. Do not place the unit near televisions, personal 
computers, magnetized cards (bank cards, commuter passes) or other devices easily influenced by a magnet.
g Batteries• Do not peel off the covering on batteries and do not use the batteries if the covering has been peeled off.• 
Align the poles ( and ) correctly when inserting the batteries.
•  
Do not mix different types of batteries or old and new batteries.
•  
Remove the batteries if you do not intend to use the unit for a long time.
•  
Do not heat or expose to flame.
•  
Do not leave the batteries in an automobile exposed to direct sunlight for a long period of time with 
doors and windows closed.
•  
Do not attempt to recharge dry cell batteries.
•  
Battery mishandling can cause electrolyte leakage which can damage items the f\
luid contacts and may 
cause a fire. If electrolyte leaks from the batteries, consult your dealer. Wash thoroughly with water if 
electrolyte comes in contact with any part of your body.
•  
Keep the AAA LR03 batteries out of reach of children to prevent swallowing. Accidental swallowing of 
batteries can result in stomach and intestinal damage.
•  When carrying batteries in a pocket or bag, ensure no metal objects such as necklaces are placed 
together with them. Contact with metal may cause short-circuiting which can cause a fire. For safety, 
carry the batteries in the battery carrying case.

g Listening caution
Do not play your headphones or earphones at a high volume. Hearing 
experts advise against continuous extended play.
If you experience a ringing in your ears, reduce volume or discontinue use.
Do not use while operating a motorized vehicle. It may create a traffic 
hazard and is illegal in many areas.
You should use extreme caution or temporarily discontinue use in potentially hazardous situations.
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. 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:
•  
Start your volume control at a low setting.
•  
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.
Clean this unit with a dry and soft cloth.• If the unit becomes too dirty, wring a cloth 
moistened in water, wipe the dirt with it and clean 
with a dry cloth.
• Do not use solvents including benzene, thinner,  alcohol, kitchen detergent, a chemical wiper, etc. 
This might cause the exterior case to be deformed 
or the coating to come off.
