Obligations
1. This warranty will be honored only on the presentation of the original proof of purchase.
2. Transportation of the product to the service station or RIVERA factory is the responsibility of the user
unless specifically stated otherwise in this warranty. RIVERA will pay for return shipping charges if the

Exclusions
1. This warranty shall not cover adjustment of customer-operated controls as explained in the appropriate

for repair.
4. This warranty shall not apply to repairs or replacements necessitated by any cause beyond the control of
RIVERA including, but not limited to, any malfunction, defects, or failure caused by or resulting from
unauthorized service or parts, damaged or broken tubes, incorrect line voltage, improper maintenance,
modification or repair for the user, abuse, misuse, neglect, accident, fire, flood, or other Acts of God.
5. This warranty shall not apply to any loudspeaker drivers that have been damaged due to thermal destruc-
tion, or physical destruction such as moisture, rips, tears, shock, or transport.
6. Responsibility for any repair of any RIVERA product sold outside of U.S. boundaries is borne by the
RIVERA representative in that particular country or territory. Also, the warranty term and conditions may
be different from those stated above. Please contact the RIVERA distributor or dealer in your country for
more information.
The foregoing is in lieu of all other expressed warranties, and RIVERA does not authorize any party to assume
for it any other obligation or liability. In no event shall RIVERA be liable for special or consequential dam-
ages arising from the use of this product, or for any delay in the performance or this warranty due to causes
beyond our control. Some states do not allow limitations on how long an implied warranty lasts and/or do
not allow the exclusion or limitation of consequential damages, so the above limitations on implied warranty
and consequential damages may not apply to you. This warranty gives you specific legal rights. You may have
other rights that vary from state to state.
