Limited Warranty

The ACM6000 is warranted to be free from defects in materials and workmanship for a period
of one year from the date of purchase. If within the warra n ty period your instrument should
become inoperative from such defects, the unit will be repaired or replaced at UEi’s option.
This warra n ty covers normal use and does not cover damage which occurs in shipment or 
failure which results from alteration, tampering, accident, misuse, abuse, neglect or improper
maintenance. Batteries and consequential damage resulting from failed batteries are not 
covered by warra n ty. 

Any implied warranties, including but not limited to implied warranties of merchantability
and fitness for a particular purpose, are limited to the express warranty. UEi shall not be
liable for loss of use of the instrument or other incidental or consequential damages,
expenses, or economic loss, or for any claim or claims for such damage, expenses or 
economic loss. A purchase receipt or other proof of original purchase date will be required
before warra n ty repairs will be rendered. Instruments out of warra n ty will be repaired (when
r e p a i rable) for a service charge. Return the unit postage paid and insured to:
