Thanks, Guy. Very helpful.

Now that you've clarified, I am embarrassed to say that I already learned this after I bought the flash a couple of years back, but just completely forgot! My brain wants to translate "RC" as "radio control" when Panasonic means "remote control."

Indeed, confusing or at best, misleading.

They should have named it IR control as that is what it uses. The slaves respond to IR signals from the master flash. The master flash can have an IR passing filter over it to stop interference from the final trigger flash.
