Limited Warranty

All products manufactured by Seller are warranted to be free from defects in 
material and workmanship for a period of one (1) year, unless otherwise 
specified, from date of shipment and to conform to applicable specifications, 
drawings, blueprints and/or samples. Seller’s sole obligation under these 
warranties shall be to issue credit, repair or replace any item or part thereof 
which is proved to be other than as warranted; no allowance shall be made for 
any labor charges of Buyer for replacement of parts, adjustment or repairs, or 
any other work, unless such charges are authorized in advance by Seller.

If Seller’s products are claimed to be defective in material or workmanship or not 
to conform to specifications, drawings, blueprints and/or samples, Seller shall, 
upon prompt notice thereof, either examine the products where they are located 
or issue shipping instructions for return to Seller (transportation-charges 
prepaid by Buyer). In the event any of our products are proved to be other than 
as warranted, transportation costs (cheapest way) to and from Seller’s plant, will 
be borne by Seller and reimbursement or credit will be made for amounts so 
expended by Buyer. Every such claim for breach of these warranties shall be 
deemed to be waived by Buyer unless made in writing within ten (10) days from 
the date of discovery of the defect.

The above warranties shall not extend to any products or parts thereof which 
have been subjected to any misuse or neglect, damaged by accident, rendered 
defective by reason of improper installation or by the performance of repairs or 
alterations outside of our plant, and shall not apply to any goods or parts thereof 
furnished by Buyer or acquired from others at Buyer’s request and/or to Buyer’s 
specifications. Routine (regularly required) calibration is not covered under this 
limited warranty. In addition, Seller’s warranties do not extend to the failure of 
tubes, transistors, fuses and batteries, or to other equipment and parts 
manufactured by others except to the extent of the original manufacturer’s 
warranty to Seller.

The obligations under the foregoing warranties are limited to the precise terms 
thereof. These warranties provide exclusive remedies, expressly in lieu of all 
other remedies including claims for special or consequential damages. SELLER 
NEITHER MAKES NOR ASSUMES ANY OTHER WARRANTY WHAT-
SOEVER, WHETHER EXPRESS, STATUTORY, OR IMPLIED, INCLUDING 
WARRANTIES OF MERCHANTABILITY AND FITNESS, AND NO PERSON 
IS AUTHORIZED TO ASSUME FOR SELLER ANY OBLIGATION OR 
LIABILITY NOT STRICTLY IN ACCORDANCE WITH THE FOREGOING.
