Warranty information
This is to certify that Series 48 lasers are guaranteed by SYNRAD, Inc. to be free of all defects in materi-
als and workmanship for a period of one year from the date of purchase. This warranty does not apply to
any defect caused by negligence, misuse (including environmental factors), accident, alteration, or
improper maintenance.
If, within one year from the date of purchase, any part of the Series 48 laser should fail to operate,
contact the SYNRAD Customer Service department at 1.800.SYNRAD1 (outside the U.S. call

date of purchase, model number and serial number of the unit, and a brief description of the problem.
When returning a unit for service, a Return Authorization (RA) number is required; this number must
be clearly marked on the outside of the shipping container in order for the unit to be properly processed.
If replacement parts are sent to you, then you are required to send the failed parts back to SYNRAD for
evaluation unless otherwise instructed.
If your Series 48 laser fails within the first 45 days after purchase, SYNRAD, Inc. will pay all shipping
charges to and from SYNRAD when shipped as specified by SYNRAD Customer Service. After the first
45 days, SYNRAD will continue to pay for the costs of shipping the repaired unit or replacement parts
back to the customer from SYNRAD. The customer, however, will be responsible for shipping charges
incurred when sending the failed unit or parts back to SYNRAD or a SYNRAD Authorized Distributor.
In order to maintain your product warranty and to ensure the safe and efficient operation of your Series
48 laser, only authorized SYNRAD replacement parts can be used. This warranty is void if any parts
other than those provided by SYNRAD, Inc. are used.
SYNRAD, Inc. and SYNRAD Authorized Distributors have the sole authority to make warranty state-
ments regarding SYNRAD products. SYNRAD, Inc. and its Authorized Distributors neither assumes nor
