Viewing and adjusting the output volume

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 [98 dB] attenuation). The audio level can be adjusted from the front panel or under RS-232/RS-422 or Ethernet control.

	buttons that may be lit.
2.	To enter Audio mode, press and hold the Audio button until the button begins
	to blink red, then release the button.
