In addition to any purchase price that Akai may charge as consideration for Akai selling or
otherwise transferring this service manual (“Manual”) to you, if you are not a service and repair
facility (“Service Center”) authorized by Akai in writing to be an authorized Service Center, Akai
sells or transfers the Manual to you on the following terms and conditions:
Only Service Centers authorized by Akai in writing are authorized to perform service and repairs
covered by an Akai 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 product or part thereof, any and all warranties
of Akai as to that product and any service contract with Akai for that product shall be
voided and shall no longer apply for such product, even if your services or repairs were
done in accordance with the Manual.
All service or repairs done by you or with reference to the Manual shall be solely your
responsibility, and Akai 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 service or
repairs. You agree that all such work will be performed in a competent, professional and safe
manner at all times and to indemnify and fully hold Akai 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 does not give you the right to copy the Manual,
and you agree not to copy the Manual without the written authorization of Akai. Akai has no
obligation to provide to you any correction of, or supplement to, the Manual, or any new or
superseding version thereof.
Akai shall have the right to refuse to sell or otherwise transfer repair parts or materials to you in
its sole discretion. You shall not use, sell or otherwise transfer spare or replacement parts
supplied by Akai to you (i) to repair or be used in products 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 or the use
thereof on behalf of Akai or in your own name.
The foregoing describes the entire understanding related to sale or transfer of the Manual to you,
and no other terms shall apply unless in a writing signed by an authorized representative of Akai.
All Trademarks are property of their respective companies.
