Syntax:
Reply:
The "X" (reset) command stops a file that is presently playing (via "P" command only, AMBIENT.WAV is not
affected). If the ambient loop switch (Q) is closed and AMBIENT.WAV is on the SD card, it will restart when
the “X” stops another file.
Prop-1 Example
In this example a file that was previously started, either manually or using a "P" command, will be stopped
and the random play list will be reset. Note that the reset command sets the channel levels and playback
speed to 100%.
