Main control

Indicates how you operate the intercom while riding. All intercoms have buttons, but some models also feature a rotary knob for extra convenience.

• Rotary knob (scroll wheel): Allows you to easily adjust volume, calls, or other functions. Known as 'jog dial' on Sena or 'control wheel' on Cardo.
• Push buttons: Standard buttons for controlling volume, calls, and music. Reliable and simple, but slightly less quick to operate than a rotary knob.
