16. Warranty
OAKTON warrants this controller to be free from significant deviations in material
and workmanship for a period of three years from date of purchase. If repair or
adjustment is necessary and has not been the result of abuse or misuse within
the warrantied time period, please return—freight prepaid—and correction will
be made without charge. OAKTON alone will determine if the product problem is
due to deviations or customer misuse.
Out-of-warranty products will be repaired on a charge basis.
17. Return of items
Authorization must be obtained from our Customer Service Department before
returning items for any reason. When applying for authorization, please include
data regarding the reason the items are to be returned. For your protection, items
must be carefully packed to prevent damage in shipment and insured against possi-
ble damage or loss. We will not be responsible for damage resulting from careless or
insufficient packing. A restocking charge will be made on all unauthorized returns.
NOTE: We reserve the right to make improvements in design, construction, and
appearance of products without notice.
