scroll box appears.
2. Click and drag the slider or click on the scroll up button or the
scroll down button until the desired value is visible.
NOTES: • As an alternative to steps 1 and 2, or to listen to
the audio as you make adjustments, click on the up
button or down button.
• Table 8 , on the on the next page, defines the value
of each audio volume step.
