Why doesn't my remote work?

[AC Question]

I have a Panasonic SC-PM46 stereo and the remote does not work and displays Remote 2 on the stereo since I've changed the batteries. How can I make it work again?

Welcome to Android Central! This is an Android site, so I'm not sure if you'll find good answers here for your stereo system. Or are you using some sort of Android-based universal remote?
