Only Service Centers authorized by ION Audio in writing are authorized to perform service and
repairs covered by an ION Audio 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 ION Audio product or part thereof, any and all warranties
of ION Audio as to that product and any service contract with ION Audio for that product shall be
voided and shall no longer apply for such product, even if your services or repairs were done in

and ION Audio 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 ION Audio 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, ION Audio does not give you the right to copy the
Manual, and you agree not to copy the Manual without the written authorization of ION Audio.
ION Audio has no obligation to provide to you any correction of, or supplement to, the Manual, or
any new or superseding version thereof.
