What are some things this Warranty does not cover?

1. THIS WARRANTY DOES NOT COVER ANY SOFTWARE THAT

RESTORATION OF DATA OR RECORDS, OR THE REINSTAL-

provided by this Warranty.

grounded outlets (including compliance with electrical and 
safety codes of the most current electrical code), without the 
use of any adapters or other connectors.

2. The CPS Product must have been plugged directly into the 

power source and the equipment connected to the CPS 
Product must be directly connected in the CPS Product, not 
“daisy-chained” together in serial fashion with any extension 
cords, another Product or device similar to the CPS Product, 
surge suppressor, or power tap. Any such installation voids
