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.
