Press Left menu button.
The Bulk EQ menu appears with Center channel
selected.
Pink noise will appear at the center channel

The standard response curve should appear over
the average of the displayed mid-frequency peaks.
If this is not the case, the scope setup step may
have been performed incorrectly. See Section 4.3,
first step.
Press the center menu button to move cursor down

Slowly move the front-panel knob to adjust the
low-frequency response as close as possible to the
