Intro: What This Flex EX2 Pairing Tutorial Covers
– Hello, my name’s John Stelman. I’m with Mazzella Companies. In this little tutorial we’ll show you how to pair this with your receiver, Magnetek Flex EX2 system, that is not paired to our receiver.
When Do You Need to Pair a Spare Flex EX2 Transmitter?

Always start with the stop switch pulled out and your transmitter off.
Step 2: Hold Buttons 1 and 3 and Power On the Transmitter
With our stop pulled out and our start switch off, we will hold in buttons one and three and turn on our start.
Step 3: Complete Pairing Pressing Receiver and Third Button
We will release, we’ll get a green flashing light with an orange light with it, and then we will hold both, pairing with our third button, and we’ll get our green status light, and everything should be connected.
