Viewing and Adjusting the Local Output Volume

The audio level of each local 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, USB port, or Ethernet control. The default volume is 100% (no attenuation).

NOTE: Output volume is protected when front panel Lock mode 2 is selected. You can view the volume in Lock mode 2 but you cannot adjust it from the front panel

(see “Setting the Front Panel Locks (Executive Modes)” on page 59).

be selected in step 3.
