In addition to any purchase price that Alesis may charge as consideration for Alesis selling or 
otherwise transferring this service manual (“Manual”) to you, if you are not a service and repair 
facility (“Service Center”) authorized by Alesis in writing to be an authorized Service Center, 
Alesis sells or transfers the Manual to you on the following terms and conditions: 
 
Only Service Centers authorized by Alesis in writing are authorized to perform service and repairs 
covered by an Alesis 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 Alesis product or part thereof, any and all 
warranties of Alesis as to that product and any service contract with Alesis 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 Alesis 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 Alesis 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, Alesis does not give you the right to copy the 
Manual, and you agree not to copy the Manual without the written authorization of Alesis.  Alesis 
has no obligation to provide to you any correction of, or supplement to, the Manual, or any new or 
superseding version thereof. 
 
Alesis 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 Alesis 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 Alesis or the use 
thereof on behalf of Alesis 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 
Alesis.
