Some things I've tried: I take the batteries out of the remote if I'm not going to use it for a few days. This helps preserve them. Occasionally, if you open the battery compartment and spin the batteries in their place with your thumb, the signal will reset. Also, I have taken a battery out and put it back in, which also made the remote work. In the settings menu, you can see what percentage the batteries have left. Whenever I am able to make it work with batteries I have, the screen never reads "batteries low, replace." There may be 30% or so left, which should be adequate - not!
