E. WARRANTY AND RETURNS

We back our products better than most companies --
not just 90 days, but one full year. Our Attorney
insists we supply the following lengthy description:

LIMITED ONE YEAR WARRANTY: Autek
Research warrants to the original consumer
purchaser that its products shall be free of defects in
workmanship and materials from one year from date
of purchase.

WARRANTY LIMITATIONS: This limited
warranty does not cover, and we are not responsible
for, any product which has been modified by the
owner, or any malfunction or failure resulting from
improper use, improper applied voltage, improper
service or repair by the owner or his agent, or from
abuse, neglect, accident, lightning damage, fire, use
contrary to instructions, or other causes beyond the
control of Autek Research. This warranty is made to
the original consumer purchaser only, and is
effective only upon presentation of documented
evidence of provable date of purchase.

This warranty covers only Autek products, used for
purposes as advertised. We are not responsible for
incidental or consequential damages. Some states do
not allow exclusion or limitation of incidental or
consequential damages, so the above limitation or
exclusion 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.

CHECKLIST WHEN RETURNING A UNIT:

1. Enclose definite proof of purchase date, as
described above with ANY return, unless you
simply wish repair out of warranty. In this case,
enclose a check or MO for a minimum of $17.00, as
described above, plus $15 outside North America.

2. ANY RETURN not complying with the above
instructions will waste time and is subject to an
additional $3 charge for correspondence, or return,
COD, without any action taken. FOLLOW THE
ABOVE INSTRUCTIONS.

3. Enclose a detailed description of the problem and
above checks, proof of purchase, date, etc. INSIDE
the package. Do not send separate correspondence
explaining that you are returning the unit. Put
everything INSIDE THE PACKAGE.

4. Allow 1-3 weeks for any repair, plus up to 2
weeks two-way shipping in USA. Please don t write
about the status of the repair before this time. (Only
