This warranty does not cover, for example: cosmetic damage (includes dropped units and cracked screens), normal wear and tear, improper operation, improper voltage supply or power surges, signal issues, damages from shipping, acts of God, any type of customer misuse, modifications or adjustments, as well as installation and set-up issues or any repairs attempted by anyone other than by the Double Power Service Center."
