from the date of original purchase for use. This Warranty does not cover damage resulting from misuse or
abuse, or lack of reasonable care, or inadequate repairs performed by unauthorized service centers.
Performance of repairs or replacements under this Warranty is subject to submission of the sales slip.
Shipment of defective items for repair under this Warranty will be at the customer's own risk and expen-
se. This Warranty is valid for the original purchaser only.

AKG warrants AKG products against evident defects in material and workmanship for a period of one year
and agrees to repair or, at our option, replace any defective unit without charge for either parts or labor.
This Warranty does not cover dry or rechargeable batteries.
Important: This Warranty does not cover damage resulting from accident, misuse or abuse, lack of rea-
sonable care, the affixing of any attachment not provided with the product, loss of parts, or connecting the
product to any but the specified receptacles. This Warranty is void unless service or repairs are performed
by an authorized service center. No responsibility is assumed for any special, incidental, or consequential
damage. However, the limitation of any right or remedy shall not be effective where such is prohibited or
restricted by law. Simply take or ship your AKG products prepaid to our service department. Be sure to
include your sales slip as proof of purchase date. (We will not repair transit damage under the no-charge
terms of this Warranty.)
Note: No other warranty, written or oral, is authorized by AKG Acoustics.
This Warranty gives you specific legal rights, and you may also have other rights which vary from state to
state. Some states do not allow the exclusion or limitation of incidental or con-sequential damage or limita-
tions on how long an implied warranty lasts, so the above exclusion and limitations may not apply to you.
