I’m on my second 4X2 True Matrix HDMI 1.3a Powered Switch w/ Remote (Rev. 3.0) with the first one ready to be shipped back for replacement. When I received the new switch I noticed that the range of the remote was about half of that of the old remote and the spare remote in the bedroom.

The most likely cause was a low battery. Unfortunately, I didn’t have a spare 2025 “watch battery” at the house. I did have a fresh 2032 battery. Hell, I thought, why not? Even the circuit board in the remote has 2032 printed on it. It might have nothing to do with the preferred battery type, but I went ahead and replaced it with the 2032, which did fit.

The range is back to working the same as that of the other remotes. It’s possible this might eventually fry the remote, so if you choose to go this route then you’ve been warned that it could be damaged.
