The Bose A20™ Aviation Headset provides a
that allows you to use your headset with an external audio source such as a
portable GPS or a portable audio device. The connector is located at the
bottom end of the control module as shown.
Your headset includes a
external audio device. Plug one end of the adapter cable into the headphone
plug on your device and the opposite end into the headset AUX audio input.
Note: None of the functions of a connected audio source are controlled by the
control module.
Note: This feature will not work unless the multifunction switch is turned on.
Note: When the headset is running on battery power only, and it is not plugged
into an intercom, it will shut off even when there is an auxiliary audio input present.
To use the headset when unplugged from the intercom to listen to auxiliary input
audio or as a Bluetooth
recommend you disable the Auto Off feature for uninterrupted functionality.
