To pair your Calisto B70 headset with the Bluetooth USB adapter:
  1. Start with the headset powered off. On the headset, press and hold the call control button for 4-6 seconds, until the light on the headset starts flashing an alternating red-blue. Release the button and set the headset aside.
  2. With the USB adapter plugged into one of the USB ports in your computer, pinch the pairing button for about 2 seconds, until the light on the adapter starts flashing an alternating red-blue. NOTE: Take caution when placing the adapter into pairing. Rather than pressing down on the adapter, pinch it with both fingers as illustrated above to avoid damage to the USB adapter and port.
When the lights on the headset and adapter stop flashing, the pairing process is complete. TIP: If you are performing this procedure on a Mac, and the devices don't pair within about 15 to 20 seconds (the lights don't stop flashing red-blue), reboot your computer to complete the pairing process.
