4.4. AUDIO SOURCES AND PRIORITIES
If two connected audio sources try to play audio simultaneously, the cardo BK-1 automatically determines
which to play through the speakers based on the priority of the connected devices.
Higher Priority
1. Mobile phone audio or GPS instructions
*
2. Intercom/Click-to-Link (CTL)
3. A2DP (Stereo Bluetooth) audio
4. Multi-Port–(for corded connection i.e. music players)
*GPS instructions from Smartphone GPS Apps are prioritized like A2DP audio

Lower Priority
• Incoming mobile phone calls will interrupt ongoing intercom calls
• Incoming intercom calls will interrupt the A2DP audio source
• Click-to-Link® calls and Intercom calls have the same priority. A Click-to-Link request cannot interrupt
an Intercom call in progress, and vice-versa.
IC (Intercom) Busy Tone: If you are on a mobile call, Click-to-Link call, or receiving GPS instructions and
Cyclist A or Cyclist B try to connect to you for an IC Call, you will both hear a busy tone (double beep).
