Since the light wasn't working with the old remote, I got a replacement remote and wireless unit that I installed. Now the light and fan work, but only from about 5 feet or less. The directions say that the antenna has to be "showing." Does that mean that I have to have the wire coming OUT OF the screw hole? (I've never seen that on a ceiling fan before.). I did go inside and drop the antenna down a bit from the unit, within the metal housing of the fan itself, but that only helped a little bit.

What is the remote for?
Basic trouble shooting for IR remote.

Make sure remote has fresh batteries
Make sure the IR receiver on the equipment is clean and has no obstructions within the line of site
Make sure there are no obstructions in a direct line between remote and receiver.
