The current setting of either the Main or Auxiliary Volume Control is displayed as a level bar on the Reply
Key, above the Reply Key text. Turning these controls clockwise or counter-clockwise, increases or
decreases the length of the relevant control bar.
The most recently moved control is displayed. If the Auxiliary Volume level setting is displayed and the
Auxiliary Volume Control is static for 2 seconds, the display reverts to showing the Main Volume level
setting. (The auxiliary level bar is displayed as a broken line to distinguish it from the main level bar).
The level bars are graded in 0.5 steps from a minimum setting of 0.0 (off) to a maximum setting of 10.0
(approximately +12 dB). Each 0.5 step corresponds to 1 pixel of the level bar. The default setting for both
controls is 5.0 (approximately 0 dB).
Pressing and holding the auxiliary control pot switch shows the current level setting for each DAK. There
is no LED indication for this switch action.
