In addition to the warranty, STANDARD HORIZON includes a lifetime “flat
rate” program to provide service after the warranty period has expired. If you
wish to obtain the flat rate price for out-of-warranty repair, you must include
the information on the Owner’s Record with the unit when you return it to
your Dealer or to STANDARD HORIZON.
Lifetime Flat Rate Service Program: For the original Owner only, for the
lifetime of the unit, STANDARD HORIZON will repair the unit to original speci-
fications.
Note: The flat rate amount is payable by the Owner only if STANDARD HO-
RIZON or the STANDARD HORIZON Dealer determines that a repair is
needed. After the repair, a 90-day warranty will be in effect from the date of
return of the unit to the Owner.
This service program is not available for equipment which has failed as a
result of neglect, accident, breakage, misuse, improper installation or modi-
fication, or water damage (depending on the product).
