product by sending in the completed warranty card.

This warranty explicitly excludes power supplies and included cables which may

In  the  event  that  MIDIMAN  receives  written  notice  of  defects  in  materials  or
workmanship from such an original purchaser, MIDIMAN will either replace the
product, repair the product, or refund the purchase price at its option. In the event
any repair is required, shipment to and from MIDIMAN and a nominal handling
charge  shall  be  born  by  the  purchaser.  In  the  event  that  repair  is  required,  a
Return  Authorization  number  must  be  obtained  from  MIDIMAN.    After  this

package with a description of the problem and the Return Authorization clearly
written on the package.

In the event that MIDIMAN determines that the product requires repair because
of user misuse or regular wear, it will assess a fair repair or replacement fee.  The
customer  will  have  the  option  to  pay  this  fee  and  have  the  unit  repaired  and
returned, or not pay this fee and have the unit returned unrepaired. 

The  remedy  for  breach  of  this  limited  warranty  shall  not  include  any  other
damages.  MIDIMAN  will  not  be  liable  for  consequential,  special,  indirect,  or
similar  damages  or  claims  including  loss  of  profit  or  any  other  commercial
damage, even if its agents have been advised of the possibility of such damages,
and in no event will MIDIMAN's liability for any damages to the purchaser or
any other person exceed the price paid for the product, regardless of any form of
the  claim.  MIDIMAN  specifically  disclaims  all  other  warranties,  expressed  or
implied. Specifically, MIDIMAN makes no warranty that the product is fit for
any particular purpose.

This warranty shall be construed, interpreted, and governed by the laws of the
state  of  California.  If  any  provision  of  this  warranty  is  found  void,  invalid  or
unenforceable, it will not affect the validity of the balance of the warranty, which
shall  remain  valid  and  enforceable  according  to  its  terms.  In  the  event  any
remedy  hereunder  is  determined  to  have  failed  of  its  essential  purpose,  all
limitations of liability and exclusion of damages set forth herein shall remain in
full force and effect.
