Important! Before you begin working on your Harmony 900, you must discharge any static electricity you
may be carrying around. Ideally, you should wear an anti-static wrist strap as you work. If you do not own
an anti-static device, at least touch a grounded appliance (the metal on the back of a computer tower works
well) before you begin working. The components inside the H900 are sensitive to static electricity so it is
very important to take these precautions!
Before you get started, familiarize yourself with the parts pictured below.
