WARRANTY

Maple Systems warrants each product to be free from electrical and mechanical defects in materials and

workmanship for a period of two years from the date of shipment. This warranty does not apply to

defects in the Products caused by abuse, misuse, accident, casualty, alteration, negligence, repair not

authorized by Maple Systems, use on current or voltages other than specified by Maple Systems, or

application or installation not in accordance with published instruction manuals. This warranty is in lieu

of any other warranty either expressed or implied.
Maple Systems’ liability is limited to the repair or replacement of the Product only, and not costs of

installation, removal, or damage to user’s property or other liabilities. If Maple Systems is unable to

repair or replace a nonconforming Product, it may offer a refund of the amount paid to Maple Systems

for such Product in full satisfaction of its warranty obligation. Maximum liability of Maple Systems is

the cost of the Product.
Information furnished by Maple Systems, Inc., is believed to be accurate and reliable. However, no

responsibility is assumed by Maple Systems for the use of this information nor for any infringements of

patents or other rights of third parties which may result from its use. No license is granted by

implication, or otherwise, under any patent or patent rights of Maple Systems, Inc. Maple Systems

retains the right to revise or change its products and documentation at any time without notice.

IF SERVICE IS REQUIRED

Package the unit in its original packaging container or, if unavailable, any suitable rigid container. If a

substitute container is used, surround the unit with shock absorbing material; damage in shipment is not

covered by the warranty. Include a letter with the unit describing the difficulty and designating a contact

person. Send to the following address: Maple Systems, Inc., 808 134th Street SW, Suite120, Everett,

Systems may be returned. All RMAs must be accompanied with a written purchase order for tracking

purposes or, in the case of out-of-warranty repairs, for repair charges on a time and material basis.
All returns will be tested to verify customer claims of noncompliance with the product warranty.

Improper return packaging which makes verification impossible will void the warranty. Products

passing the tests will be returned “AS IS” to the customer.
If noncompliance is verified and is not due to customer abuse or the other exceptions described with

product warranty, Maple Systems will, at its option, repair or replace the Product returned to it, freight

prepaid, which fail to comply with the foregoing warranty, provided Maple Systems is notified of such

noncompliance within the one-year warranty period.
