If you need to reset your RC73 DIRECTV remote, there are a few different ways that you can do so. One way is to hold down the MUTE and SELECT buttons at the same time for three seconds. This should reset your remote. Another way is to unplug your DIRECTV receiver for about 30 seconds and then plug it back in. Once it has restarted, try using your remote again. If neither of these methods work, you may need to replace your batteries or get a new remote altogether.
