SAFETY NOTICE

FCC Warning

This equipment generates, uses and can radiate radio frequency energy, and, if not installed in

accordance with the instructions contained herein, may cause interference to radio communications.

It has been tested and found to comply with the limits for a Class A computing device pursuant to

Subpart J of Part 15 of the Federal Communications Commission rules, which are designed to

provide reasonable protection against such interference, when operating in a commercial

environment.

Operation of this equipment in a residential area is likely to cause interference. In this case, the user

is required to take whatever measures are necessary to correct the interference at the user’s

expense.

WARRANTY AND SERVICE

AdvantechAMT warrants to the Purchaser that the Products and any Repaired Products (Repairs)

will be free from defects in material and workmanship for a period of two years from the date of

shipment to the Purchaser.

AdvantechAMT‘s

obligation under this warranty is limited to replacing or repairing, at

AdvantechAMT's option, Products or Repairs found by AdvantechAMT to be defective within the

warranty period. All such replacements and repairs shall be performed at facilities designated by

AdvantechAMT and shall be performed only after the customer has received a Return Material

Authorization (RMA) number from AdvantechAMT and has returned the Product to AdvantechAMT,

shipping and insurance prepaid by Purchaser.

The returned Product must be accompanied by the customer's name, address and telephone

number, the model and serial number of the Product, a statement of the purchase date and a

detailed description of the problem. Products and Repairs returned by Purchaser shall be repaired

by AdvantechAMT using new or refurbished parts and shall be returned to Purchaser by

AdvantechAMT, shipping prepaid by AdvantechAMT.

This warranty shall immediately become null and void if, in AdvantechAMT's sole judgment, the

Product has been subject to unauthorized modification, misuse, abuse, neglect, accident, improper

installation or application, alteration or neglect in use, storage, transportation or handling, or if the

serial number and/or other Product markings have been removed, defaced or altered.

AdvantechAMT may, at its discretion, perform out-of-warranty repairs at AdvantechAMT facilities in

exchange of customary charges, or offer a written agreement extending the terms of this warranty at

a price stated in such agreement. All repairs performed out of warranty or pursuant to an extended

warranty agreement shall be subject to all of the applicable limitations and procedures of this

Agreement.

The above warranties are in lieu of all other warranties, expressed, implied, or statutory or arising by

custom of trade usage, including any warranty of merchantability of fitness for any unique, special or

express purpose, and of all other obligations of liabilities whether in contract, tort or otherwise
