extent and conditions of Limited Warranty are as follows:

1. Authorized Dealer Installed Products: 

PrecisionPower will either repair or replace at no charge,

to the original purchaser, any unit which 

PrecisionPower’s examination discloses to be defective

and under warranty, provided the defect occurs within three (3) years from the date of original
purchase when the unit is installed by an Authorized Dealer and the product is returned immedi-
ately to 

PrecisionPower. This warranty is not transferable.

2. Non-Authorized Dealer Installed Products: 

PrecisionPower will either repair or replace at no

charge, to the original purchaser, any unit which 

PrecisionPower’s examination discloses to be

defective and under warranty, provided the defect occurs within ninety (90) days from the date of
purchase and the product is returned immediately to 

PrecisionPower. Warranty claims beyond

ninety (90) days for Non-Authorized Dealer Installed Products will be for parts only and will
extend for one (1) year from the date of purchase. This warranty is not transferable.

3. The date of purchase and proof of Authorized Dealer Installation of a PrecisionPower product
must be established by an original sales receipt which must accompany the article being re-
turned for warranty work.

tory serial number removed or defaced. All products received (by 

PrecisionPower) for in war-

ranty or out of warranty repair, with their original serial numbers removed or defaced, will NOT be
repaired and will be returned to sender, freight collect. Refer to original packaging for the serial
number of your component speakers.

5. The provisions of this warranty shall not apply to any

been connected, installed, or adjusted other than in accordance with the instructions furnished in
PrecisionPower’s owner’s manual. Nor shall this warranty apply to any part which has been
subject to misuse, neglect, or accident.

6. PrecisionPower does not authorize any other persons to assume any other liability in connec-
tion with its products. THIS WARRANTY IS THE ONLY EXPRESS WARRANTY MADE BY
PRECISIONPOWER APPLICABLE TO ITS PRODUCTS. ANY IMPLIED WARRANTY OR MER-
CHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE APPLICABLE TO
PRECISIONPOWER PRODUCTS IS LIMITED IN DURATION TO THE DURATION OF THIS
LIMITED WARRANTY.  PRECISIONPOWER SHALL NOT BE LIABLE FOR THE INCIDENTAL,
CONSEQUENTIAL, OR COMMERCIAL DAMAGES RESULTING FROM THE BREACH OF THIS
WRITTEN WARRANTY. Some states or provinces do not allow the exclusion or limitation of
incidental or consequential damages or limitations on how long an implied warranty lasts; so the

tion of warranted defects. If improper operation of your
