WARRANTY
Midian Electronics, Inc., warrants this product to be
free from defects in material and workmanship for
two years from date of shipment. If such malfunction
occurs, it will be repaired or replaced (at our option)
without charge for materials or labor if returned to the
factory. This warranty does not apply to any parts
damaged due to improper use--including accident,
neglect, unreasonable use, and improper installation--
or to unauthorized alterations or modifications of the
equipment. It does not extend to damage incurred by
natural causes such as lightning, fire, floods, or other
such catastrophes, nor to damage caused by
environmental extremes, such as power surges
and/or transients. It does not extend to
microprocessors, if it is determined by Midian that the
failure of a micro is due to static damage, application
of improper voltages to the unit, or other problems not
related to circuit design. In such case or in the case of
a desire to update the micro to a different version of
software, such request must be specified in writing,
and there will be a charge agreed upon by both
parties.
This product is warranted to meet published
specifications and to operate as specified only when
properly installed in radio equipment which complies
with U.S. FCC specifications and the applicable radio
manufacturer's specifications. Midian Electronics is
not responsible for any operational problems caused
by system design, outside interference, or improper
installation. Equipment for repair can be returned to the factory
without prior written authorization. A brief letter
describing the nature of the defect should be included
with the merchandise. Repair by other than Midian
Electronics, Inc., will void this warranty. In-warranty
merchandise must be shipped, freight prepaid, to
Midian Electronics. Midian Electronics will return,
freight prepaid via UPS ground, the repaired or
replaced equipment to purchaser, within the United
States. Out-of-warranty repairs will be billed at the
rate of $60 per hour, plus replacement parts.
This warranty applies to the original purchaser of the
equipment only. Midian Electronics is not liable under
this warranty, or any implied warranty, for loss of use
or for other consequential loss or damage
experienced by the purchaser. Some states do not
permit the exclusion or limitation of implied warranties
or consequential damages. This warranty provides
special legal rights, and the purchaser may have
other rights that vary from state to state.
