Those manuals are a big improvement over the military manual I was using. The trigger level controls are just that. They set the point on the waveform where the triggers occur. Sensitivity is

Only the TM504, and TM506 have a high power compartment. This would be the SINGLE right-most compartment of the TM504 and TM506. The high powered compartment is not needed for the SC504. The SC504
