Calisto II: How to Pair the Headset with the Mini USB Adapter

How do I pair the headset with the Bluetooth USB adapter shown below?

Note: If you have the longer USB adapter (the BUA-200), click here for the pairing instructions.

To pair your Calisto B70 headset with the mini 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. Plug the USB adapter into one of the USB ports in your computer. When the light on the headset stops flashing, the devices have paired successfully.

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.
