Warranty and Service
2.1 Warranty
In order for the factory warranty to be valid, the installations in a certified aircraft
must be accomplished by an FAA-(or other ICAO agency) certified avionics shop
and authorized PS Engineering dealer. If the unit is being installed by a non-
certified individual in an experimental aircraft, a factory-made intercom harness
must be used for the warranty to be valid.
PS Engineering, Inc. warrants this product to be free from defect in material and
workmanship for a period of three (3) years from the date of installation as recorded
in aircraft logbook and/or on FAA Form 337. During the first twelve (12) months
of the three-year warranty period, PS Engineering, Inc., at its option, will send a
replacement unit at our expense if the unit should be determined to be defective
after consultation with a factory technician. For the remaining twenty-four (24)
months of the three-year warranty period, the unit must be returned to PS Engineer-
ing, Inc., or an authorized warranty service facility, for no-cost repair.
All transportation charges for returning the defective units are the responsibility of
the purchaser. All domestic transportation charges for returning the exchange or
repaired unit to the purchaser will be borne by PS Engineering, Inc. The risk of loss
or damage to the product is borne by the party making the shipment, unless the pur-
chaser requests a specific method of shipment. In this case, the purchaser assumes
the risk of loss.
This warranty is not transferable. Any implied warranties expire at the expiration
date of this warranty. PS Engineering SHALL NOT BE LIABLE FOR INCIDEN-

that has resulted from improper handling, storage or preservation, or unreasonable
use or maintenance as determined by us. This warranty is void if there is any at-
tempt to dissemble this product without factory authorization. This warranty gives
you specific legal rights, and you may also have other rights, which may vary from
state to state. Some states do not allow the exclusion of limitation of incidental or
consequential damages, so the above limitation or exclusions may not apply to you.

of the original warranty period. PS Engineering, Inc. reserves the rights to make
