and returned to the factory within fifteen (15) days after installation, and (iii) a post-installation start-up has been performed by 
an authorized service representative (portable equipment not applicable). Marshall's obligation under this warranty is limited 
to the repair or replacement at its option of any defective part. Under certain circumstances, Marshall will reimburse 
Purchaser for limited labor costs in replacing parts during a period of not more than ninety (90) days from date of shipment,

provision for portable equipment. It is understood that Marshall's obligation with respect to equipment located outside th e

2.     Any component disassembled in the field;

altered. Marshall reserves the right to accept or reject any such claim in whole or in part. Marshall will not accept the return of 
any product without prior written approval from Marshall, and all such approved returns shall be made at Purchaser's sole
