SUMMARY OF WARRANTY*
Tholin Limited warrants to you, the ORIGINAL PURCHASER and ANY SUBSEQUENT OWNER of each NEW
Tholin-Audio product, for a period of one (1) year from the date of purchase by the original purchaser (the
“warranty period”) that the new Tholin-Audio product is free of defects in materials and workmanship. We further
warrant the new Tholin-Audio product regardless of the reason for failure, except as excluded in this Warranty.
ITEMS EXCLUDED FROM THIS Tholin-Audio WARRANTY
This Tholin-Audio Warranty is in effect only for failure of a new Tholin-Audio product which occurred within the
Warranty Period. It does not cover any product which has been damaged because of any intentional misuse,
accident, negligence, or loss which is covered under any of your insurance contracts. This Tholin-Audio Warranty
also does not extend to the new Tholin-Audio product if the serial number has been defaced, altered, or removed.
WHAT THE WARRANTOR WILL DO
We will remedy any defect, regardless of the reason for failure (except as excluded), by repair, replacement, or
refund. We may not elect refund unless you agree, or unless we are unable to provide replacement, and repair is
not practical or cannot be timely made. If a refund is elected, then you must make the defective or malfunctioning
product available to us free and clear of all liens or other encumbrances. The refund will be equal to the actual
purchase price, not including interest, insurance, closing costs, and other finance charges less a reasonable
depreciation on the product from the date of original purchase. Warranty work can only be performed at our
authorized service centers or at the factory. We will remedy the defect and ship the product from the service
center or our factory within a reasonable time after receipt of the defective product at our authorized service
center or our factory. All expenses in remedying the defect, including surface shipping costs in Germany, will be
borne by us. (You must bear the expense of shipping the product between any foreign country and the port of
entry in Germany including the return shipment, and all taxes, duties, and other customs fees for such foreign
shipments.)
HOW TO OBTAIN WARRANTY SERVICE
You must notify us of your need for warranty service within the warranty period. All components must be shipped
in a factory pack, which, if needed, may be obtained from us free of charge. Corrective action will be taken within
a reasonable time of the date of receipt of the defective product by us or our authorized service center. If the
repairs made by us or our authorized service center are not satisfactory, notify us or our authorized service
center immediately.
DISCLAIMER OF CONSEQUENTIAL AND INCIDENTAL DAMAGES
YOU ARE NOT ENTITLED TO RECOVER FROM US ANY INCIDENTAL DAMAGES RESULTING FROM ANY
DEFECT IN THE NEW THOLIN-AUDIO PRODUCT. THIS INCLUDES ANY DAMAGE TO ANOTHER PRODUCT
OR PRODUCTS RESULTING FROM SUCH A DEFECT. SOME STATES DO NOT ALLOW THE EXCLUSION
OR LIMITATIONS OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THE ABOVE LIMITATION OR
EXCLUSION MAY NOT APPLY TO YOU.
WARRANTY ALTERATIONS
No person has the authority to enlarge, amend, or modify this Tholin-Audio Warranty. This Tholin-Audio Warranty
is not extended by the length of time which you are deprived of the use of the new Tholin-Audio product. Repairs
and replacement parts provided under the terms of this Tholin-Audio Warranty shall carry only the unexpired
portion of this Tholin-Audio Warranty.
DESIGN CHANGES
We reserve the right to change the design of any product from time to time without notice and with no obligation
to make corresponding changes in products previously manufactured.
