How can I see how much ambient level is being picked up by the speakers when the 572 Flow Chart is in "SENSE" mode?

Set OPTIONS switch “B” to the “UP” position. The 572’s GAIN (dB) LED’s will now display the level of ambient noise that is being picked up by the sensing speakers.

NOTE: This interrupts normal operation of the 572. Return OPTIONS switch “B” to the “DOWN” position, to restore normal operation of the 572.
