LIMITED WARRANTY (UNITED STATES)

Robert Bosch Corporation warrants new Blaupunkt audio products’and accessories it distributes in
the United States through authorized Blaupunkt dealers, or which are imported as original vehicle

equipment by the automobile manufacturer, to be free from defects in material and workmanship,
in accordance with the following:

For twelve 

 months after delivery to you, the original consumer purchaser, we will repair any

amplifier and replace any accessory which under normal conditions of use and service proves to be
defective in materials or workmanship at no charge to you.

However, this warranty does not cover

expenses incurred in the removal or reinstallation of any amp or accessory whether or not proven
defective and does not cover products not purchased from an authorized Blaupunkt dealer.

To obtain performance of this warranty, contact the nearest Blaupunkt authorized repair facility or
our nearest office. A dated purchase receipt or other proof that the product is within the warranty
period will be required in order to honor your claim. Carefully pack the unit and ship prepaid to the
servicing location. For further information, contact your local Blaupunkt retail dealer.

This warranty is limited to the original consumer purchaser and is not transferable. Specifically

from this warranty are failures caused by misuse, neglect, abuse, improper operation or

allation, dropping or damaging the faceplate, or unauthorized service or parts. Also excluded

this warranty is the correction of improper installation and the elimination of any external

electromagnetic interference.

To the extent allowed by law, this warranty sets out your exclusive remedies with respect to
products covered by it, whether for negligence or otherwise. We will not be liable for
consequential or incidental damages, losses, or expenses.

THIS WARRANT? IS IN LIEU OF ALL

OTHER EXPRESS WARRANTIES. ANY WARRANTY IMPLIED BY LAW, WHETHER FOR
MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE OR OTHERWISE, SHALL BE
EFFECTIVE ONLY FOR THE PERIOD THAT THIS EXPRESS WARRANTY IS EFFECTIVE. No attempt
to alter, modify, or amend this warranty shall be effective unless authorized in writing by an officer
of Robert Bosch Corporation.

Some states do not allow limitations on how long implied warranties last, or the exclusion or
limitation of incidental or consequential damages, so the above limitations or exclusions may not
apply to you. This warranty gives you specific legal rights and you may also have other rights
which vary from state to state.

NOTICE TO CALIFORNIA OWNERS

If your Blaupunkt car audio product needs warranty repair service and there is no authorized service
center reasonably close to you, you can return the defective unit to the dealer from whom you
purchased it. Or you can return it to any dealer who sells Blaupunkt products. The dealer may
repair or replace the unit, or, if returned to the dealer from whom purchased, he may partially
refund your money, you may take your Blaupunkt unit to any repair shop and they can repair your
unit at our expense unless the repair cost exceeds the depreciated value of the unit, but you must
contact Blaupunkt to receive authorization to do this before your unit is repaired.
