I am considering getting this, however would like to clarify how this unit operates.
When using this controlling a siren, would I need to turn one tone off, before i could turn another on?
Example: One button Wail, One Yelp. Could I hit the wail button for wail, then hit the yelp button and have it change to yelp, or would I have to turn wail off, then turn yelp on?
