Commercial Warranty
Microwave Networks, Inc. (MNI) manufactured products are warranted to be free from defect in
material and workmanship for a period of two (2) years from date of shipment. In the event of a
defect during the warranty period, Buyer will return item to the MNI depot repair facility for
repair or replacement. Repair at MNI's option may include the replacement of parts or equipment,
and all replaced parts or equipment shall be the property of MNI. Parts or equipment replaced dur-
ing the warranty period are warranted for the remainder of the original applicable warranty period
or ninety (90) days, whichever is greater. This express warranty is extended by MNI to the origi-
nal Buyer for commercial, industrial or governmental use. Such action on the part of MNI shall be
the full extent of MNI's liability and Buyer's exclusive remedy.
This warranty extends only to products manufactured by MNI, and it is expressly conditioned
upon the equipment having been installed in accordance with the installation practices accepted
by the telecommunications industry, the standard installation and configuration practices recom-
mended by MNI, and the equipment having been maintained in accordance with MNI recom-
mended standard maintenance practices. Frequency sensitive components, towers, vidicon tubes,
test equipment, batteries, and other manufacturers' products are excluded, but carry their own sep-
arate limited warranties as authorized by the individual manufacturers.
This warranty shall automatically terminate if the product is used in other than its normal and cus-
tomary manner, has been subject to misuse, accident, neglect or damage, has improper alterations
or repairs made to it, or if nonconforming parts are used in the product, unless done by a service
facility authorized by MNI to perform warranty service. An authorization to return products to
MNI under this warranty must be obtained from the MNI Customer Care Center prior to making
shipment to MNI's repair center. All returns shall be shipped freight prepaid and collect shipments
will not be accepted. MNI will prepay return freight charges on repaired and replaced products
found to be defective. There will be a minimum charge for each warranty module replacement
requested as an emergency exchange.
Because each radio system is unique, MNI disclaims liability for range, coverage, or operation of
a system as a whole under this warranty except by a separate written agreement signed by an
officer of MNI. MNI's total liability is limited to the total price of the products sold. Buyer's sole
remedy is to request MNI, at MNI's option, to either refund the purchase price, repair or replace
product(s) that are not as warranted. No action shall be brought for any breach of this contract
more than one (1) year after the accrual of such cause of action except for money due upon open
account.
This MNI warranty is given in lieu of all other warranties, either expressed or implied, which are
specifically excluded, including warranties of merchantability or fitness for a particular purpose.
In no event shall MNI be liable for any incidental or consequential damages arising from this war-
ranty.
