QUICK REFERENCE GUIDE

Pairing the Headset with your Bluetooth mobile phone

1. Make sure the headset is powered on, and that the multifunction switch

2. Press the Bluetooth

function button (B above) to activate Bluetooth.

If this is the first time you’ve activated or are attempting to pair Bluetooth,the Bluetooth indicator will flash at a slow rate alternat- ing with the Power indicator. This indicates that the headset is in “discoverable” mode and ready to be paired to a cell phone.

If the Bluetooth indicator does not flash alternately with the Power indicator flash or you are trying to pair a headset that has previously been paired with another phone, you will need to press and hold the Bluetooth function button for 5 seconds in order to put the headset into “discoverable” mode.

3. Set your phone to “discover” the Bose A20 Aviation Headset

Select “BOSE A20” on the phone.**

4. If asked for a passkey or PIN, enter 0000 (four zeros).

When pairing is complete, the Bluetooth indicator light and the green power indicator light on the control module will flash in unison.
