Users should be aware that taking the cover off from the DVR
Unit might void the warranty without consulting with seller.

Avoid same power circuit input from hair dryer, coffee makers,
curling iron, refrigerator or other appliances that may draw

protectors are recommended and at least the DVR DVR Units
must be connected properly approved power surge protector.
