This equipment has been tested and found to comply with 
the limits for a Class B digital device, pursuant to Part 15 of 
the FCC rules. These limits are designed to provide 
reasonable protection against harmful interference in a 
residential installation. This equipment generates, uses 
and can radiate radio frequency energy and, if not installed 
and used in accordance with the instructions, may cause 
harmful interference to radio communications. However, 
there is no guarantee that interference will not occur in a 
particular installation. If this equipment does cause 
harmful interference to radio or television reception, which 
can be determined by turning the equipment off and on, the 
user is encouraged to try to correct the interference by one 
or more of the following measures:

Reorient or relocate the receiving antenna.
Increase the separation between the equipment and 
receiver.
Connect the equipment into an outlet on a circuit 
different from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV 
technician for help.

For the wireless headphone, use only 3AAA 1.2V 

600mAh Nickel Metal Hydride(Ni-MH) batteries (included).

Do not dispose of the batteries in a fire. The cells may 

explode. Check with local codes for possible special 
disposal instructions.

Do not open or mutilate the batteries. Released 

electrolyte is corrosive and may cause damage to the eyes 
or skin. It may be toxic if swallowed.

Exercise care in handling batteries in order not  to short 

the battery with conducting materials such as rings, 
bracelets,

and keys. The battery or conductor may 

overheat and cause burns.

Do not attempt to rejuvenate the batteries identified for 

use with this product by heating them. Sudden release of 
the battery electrolyte may occur causing burns or irritation 
to eyes or skin.

When inserting batteries into this product, the proper 

polarity or direction must be observed. Reverse insertion 
of batteries can cause charging, and that may result in 
leakage or explosion.

Remove the batteries from this product if the product will 

not be used for a long period of time(several months or 
more)since during this time the battery could leak in the 
product.

Do not store this product ,or the batteries identified for 

use with this product, in high temperature areas. Batteries 
that are stored in a freezer or refrigerator for the purpose of
