6.8Volume (ad)justment
Mojo 2 benefits from two main volume `ranges': low and high, as indicated by the colour of the menu - button: unlit (low); white (high). As the volume is changed, Mojo 2 moves automatically into the respective volume ranges; the menu button colour changes accordingly. + With chosen devices and headphones now connected (but not on/in ear), and Mojo 2 powered on, the volume can be reduced to zero using the volume down `-` controls until both volume buttons and menu
button are unlit. From unlit, the volume can be slowly increased by pressing the volume up `+' button. Both buttons slowly change colour with changing volume level.
Always set the volume level to zero before commencing initial playback and take precautions when using Mojo 2 in high volume mode to protect from hearing damage.
