Did you say the red light didn't illuminate on the transmitter?
If that's correct, open up the battery compartment on the transmitter and turn the batteries in situ, making sure they're making proper contact. Not all AA batteries are the same diameter, some get a little stuck in the compartment and don't always make a proper connection at the + end.
