Using the Headset Auxiliary (AUX) audio input The Bose® A20® Aviation Headset provides a 1/8 inch (3.5 mm) AUX audio input 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. AUX audio input Your headset includes a 1/8 inch (3.5 mm) adapter cable to connect your 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 signal present. To use the headset when unplugged from the intercom to listen to auxiliary input audio, or using Bluetooth wireless technology to make or receive calls, we recommend you disable the Auto Off feature for uninterrupted functionality. Audio priority The Bose A20 Aviation Headset allows you to decide the priority of the audio sources you want to hear while using the headset. On the Bluetooth control module, the audio priority is controlled by the multifunction switch. On the conventional control module, the audio priority is controlled by the audio priority switch.
