Adjusting the volume using a USB keyboard

Setting Master Output Volume

The master volume of audio playback can be changed by temporarily plugging in a standard USB keyboard, and using the top two rows of keys (1 through 0, and Q through P).

The row of keys 1 through 0 controls the Channel 1 (Left) master volume, while the row of keys Q through P controls the Channel 2 (Right) master volume.

Pressing the same key multiple times successively will toggle the volume between the 1st press and 2nd press levels. The table below describes the available volume levels.
