Viewing and adjusting the output volume (audio models)

On models with audio, the audio level of each output can be displayed and adjusted through a range of 100% (no attenuation) to 0% (maximum [76 dB] attenuation). The audio level can be adjusted from the front panel or under serial port or Ethernet control. The default volume is 100% (no attenuation).

		Output volume is protected when front panel lock mode 2 is selected. You can
		view the volume in lock mode 2, but not adjust it from the front panel.

	that are lit, the lower the volume.
