Example 8: Viewing and adjusting an audio level
See figure 3-15 and figure 3-17 and the following steps for an example of viewing
and adjusting the audio level. Audio gain and attenuation is displayed differently
on the MAV 128 RCA (see the table below right) from the display on the MAV 168
and 1616, but the steps for displaying the
value are the same. For this reason, figure 3-16
and figure 3-18 show the indications displayed
on the MAV 128 RCA without duplicating all
of the actions shown in figure 3-15
and figure 3-17.
