Sets Volume level between 00.0
and 73.2
VOL:71.1\r VOL:ACK\r
Sets the Volume level to a selected
value. The incoming request is an
example of setting the volume level to
71.1
The value 00.0 turns off the volume and
73.2 is the maximum value. Any values
above 73.2 are accepted, but the level
won’t exceed the maximum value.
? Request Current Volume VOL:?\r VOL:XX.X\r

current volume level.
VOL:NACK\r
The player is in Standby Mode so
commands are ignored.
*
NOTE: The volume value MUST be three digits, written in the xx.x format, otherwise the player does not recognize the command and returns an invalid
parameter error. If a value is sent that is outside the listed limits, the volume level is clipped to the nearest valid value - either the maximum or the minimum
volume level.
