One-Year Limited Warranty

Audio-Technica professional wireless systems purchased in the U.S.A. are warranted for one year from date of purchase by Audio-Technica U.S., Inc.
( A.T.U.S.) to be free of defects in materials and workmanship. In event of such defect, product will be repaired promptly without charge or, at our
option, replaced with a new product of equal or superior value if delivered to A.T.U.S. or an Authorized Service Center, prepaid, together with the
sales slip or other proof of purchase date. 

Prior approval from A.T.U.S. is required for return.

This warranty excludes defects due to normal wear,

abuse, shipping damage, or failure to use product in accordance with the instructions. This warranty is void in the event of unauthorized repair or
modification, or removal or defacing of the product labeling.

For return approval and shipping information,

contact the Service Dept., Audio -Technica U.S., Inc., 1221 Commerce Drive, Stow, Ohio 44224.

Except to the extent precluded by applicable state law, 

A.T.U.S. will have no liability for any consequential, incidental, or special damages; any

warranty of merchantability or fitness for particular purpose expires when this warranty expires.

This warranty gives you specific legal rights, and you may have other rights which vary from state to state.

Outside the U.S.A., please contact your local dealer for warranty details.

Notice to individuals 

with implanted cardiac pacemakers or AICD devices:

Any source of RF (radio frequency) energy 

may interfere with normal functioning of the implanted device. All wire-

less microphones have low-power transmitters (less than 0.05 watts output) which are unlikely to cause difficulty,
especially if they are at least a few inches away. However, since a “body-pack” mic transmitter typically is placed
against the body, we suggest attaching it at the belt, rather than in a shirt pocket where it may be immediately adjacent
to the medical device. Note also that 

any medical-device disruption will cease when the RF transmitting source 

is turned off. Please contact your physician or medical-device provider if you have any questions, or experience any
problems with the use of this or any other RF equipment.
