Where/How do you change the MIDI channel on Yamaha YPT-200

I've looked in the manual and it only gives basic information about MIDI, I don't see anything that tells you to go to this menu or that button, etc. Does this keyboard just broadcast on all 16 channels at once? That wouldn't make sense when you're using it as a controller with other keyboards (all hooked to a computer with soft synths) because there's no way to make the keyboard competely discreet then. Please let me know what the next step is, I'm just trying to assign the YPT-200 to MIDI channel 2 to keep it discrete from my other keyboard (Roland XP-80) which is set to MIDI channel 1.
