How do you know if you have a C31 or C41?

The receiver on the top is a C31. The one on the bottom is a C41. C31 clients are actually pretty rare, having only been available for a few months. The C41 replaced it and added support for DIRECTV’s new RC71 remote(and nothing else.) So how can you tell the difference?

The first question, of course, is why you would care which one you have. For the most part, they are identical. However, if you have the C31, you’ll want the older-style remote to control it in RF mode. Both new and old remotes will control either client in IR mode, but if you plan on hiding the client behind a TV you’ll need the right RF remote.

If you look carefully at the picture above, you’ll see a logo at the lower right that only appears on the C41. It’s the RF4CE logo and it means you can use the RC71 remote in RF mode. If you see that logo, you know you have a C41. Another way is to look at the sticker on the bottom of the client.

There’s an easier way, if you have the client on the back of the TV or otherwise hidden. Using the remote you have, press {MENU} then choose “Settings&Help” then “Settings.” You’ll see a screen that shows you the model number. It looks like this (although this is from an HR44, the screens are the same)

Right there you’ll see the model number. Don’t worry about the “-700” or whatever numbers follow the dash; this is just the manufacturer code and all clients work the same no matter which manufacturer is used.
