Ceiling fan conversion to remote [View all]

So I have an existing ceiling fan that has run out of steam. It's at least 20 years old and is operated by a wall switch, with push buttons - one for the fan and one for the light. I bought a new fan with a remote and light kit. Included in the package was a warning not to install the fan with a wall mounted light dimmer or solid-state speed control. I'm not exactly sure what that means, but I THINK it means I won't be using the wall for the operation of the fan.

I've put in two ceiling fans before, so I basically know what to do, but they were just regular ones that operated by a wall switch, not a remote. My question is: do I need to cap off the wires in the wall switch and put a blank cover on it since I'll just be using the remote, or what?

TIA
