Thank you for the prompt response Neil. That's the instruction manual Fred Sweet posted earlier. I've run though that manual up and down numerous times already. I've also read pages 8, 9 and 10 thoroughly, and I don't see anything mentioned about the 3-Way toggle switch. Am I too impatient or need to have my eyes checked? lol. The switch is (kinda) shown on the manuals cover image, so you'd think they'd definitely mention it switch somewhere. But I swear it's not in there. What does that switch do exactly?
