VOLUME CONTROL, PRESET & HEADPHONE MUTE
The m905 utilizes a single rotary pushbutton encoder for control of the speaker and headphone volume
levels, level preset recall and headphone mute. Switching between speaker level and headphone
level control is done by pushing and releasing the volume control knob. The current volume levels are
indicated on the display with the active control being green and the inactive control in light gray. The
volume control is speed sensitive, so the turning the knob at a higher velocity results in faster volume
changes.
