terms and conditions:
Only Service Centers authorized by Akai Professional in writing are authorized to perform service
and repairs covered by an Akai Professional warranty (if any), and transfer of the Manual to you
does not authorize you to be an authorized Service Center. Therefore, if you perform, or if the
Manual is used to perform, any service or repairs on any Akai Professional product or part
thereof, any and all warranties of Akai Professional as to that product and any service
contract with Akai Professional for that product shall be voided and shall no longer apply

responsibility, and Akai Professional shall have no liability for any such repairs or service work.
All such service or repairs are performed at the sole risk of the person performing the

and safe manner at all times and to indemnify and fully hold Akai Professional and its successors
and assigns harmless in the event of any failure to so perform.
Your purchase of the Manual shall be for your own ultimate use and shall not be for purposes of
resale or other transfer.
As the owner of the copyright to the Manual, Akai Professional does not give you the right to
copy the Manual, and you agree not to copy the Manual without the written authorization of Akai
Professional. Akai Professional has no obligation to provide to you any correction of, or
supplement to, the Manual, or any new or superseding version thereof.
Akai Professional shall have the right to refuse to sell or otherwise transfer repair parts or

manufactured for or by third parties or (ii) to any third parties for any purpose.
You shall not make any warranties or guarantees with respect to the products of Akai
Professional or the use thereof on behalf of Akai Professional or in your own name.
