With the ultrasonic ones, use an audible track to calibrate the volume. Remember that the ultrasonics have a constant volume, so use a track with a fairly constant volume to calibrate. Trickling Stream is perfect for that. Once it's to a level where you can hear it clearly everywhere you expect to be in the room, but it's low enough volume for you at the same time, switch over to the ultrasonic and you're set.
