a new or refurbished unit. The warranty period starts from the original purchase date and 

is valid for the length of time indicated in the chart below. The decision to repair or replace 

will be made by the warranter.

LIMITED WARRANTY-LIMITS AND EXCLUSIONS

This warranty ONLY COVERS failures due to defects in materials and workmanship and 

DOES NOT COVER normal wear and tear or cosmetic damage. The warranty ALSO 

DOES NOT COVER damages that occurred during shipment, failures which are caused 

by products not supplied by the warranter, failures that result from accident, misuse, 

abuse, neglect, bug infestation, mishandling, misapplication, alteration, faulty installation, 

set-up adjustment, maladjustment of consumer control, improper maintenance, 

improper antenna, inadequate signal reception or pickup, power line surge, improper 

voltage supply, lightning, modification, commercial use (such as use in hotels, offices, 

restaurants, or other business uses) or rental use of the product, or service by anyone 

other than Retro Manufacturing, LLC, or damage that is attributable to acts of God. 

 

THERE ARE NO EXPRESS WARRANTIES EXCEPT AS LISTED UNDER 

LIMITED WARRANTY. THE WARRANTER IS NOT LIABLE FOR INCIDENTAL 

OR CONSEQUENTIAL DAMAGES RESULTING FROM THE USE OF THIS UNIT 

OR ARISING OUT OF ANY BREACH OF THIS WARRANTY. (As examples, this 

excludes damages for lost time, the cost of having someone remove or re-install an 

installed unit if applicable, travel to and from the servicer, and loss of media, data, or 

other memory contents. The items listed are not exclusive but are for illustration only.) 

ALL EXPRESS AND IMPLIED WARRANTIES, INCLUDING THE WARRANTY OF 

MERCHANTABILITY, ARE LIMITED TO THE PERIOD OF THE LIMITED WARRANTY. 

 

Some states do not allow the exclusion or limitation of incidental or consequential 

damages or limitations on how long an implied warranty lasts, so the exclusions may not 

apply to you. This warranty gives you specific legal rights, and you may also have other 

rights which vary from state to state. If a problem with this unit develops during or after the 

warranty period, you may contact your dealer or Retro Manufacturing, LLC.
