Ours was really staticky, no matter what we did, so we returned it to the manufacturer for a new one...and it does the same thing. We have to keep the sound on the handheld monitor down really low, and even then, it lets out loud blasts of static if one of us moves in bed or walks past it. It does this on both channels, and we've even moved into a new house since we've had it and nothing has helped.
Is this just the way they are, or did we get two bad ones somehow?
