Managing multiple secondary sources
The headset can connect one AUX (wired) source and up to two Bluetooth
®
( wireless) sources at a time.
If you are likely to receive important information from a particular secondary source
(such as a GPS or a warning system), you can assign priority to that source. This
insures that incoming audio from the priority source will always override other
source.
Setting the Priority (BT-AUX) switch
To assign priority to one of your secondary sources:
1. Locate the Priority (BT-AUX) switch inside the battery compartment.
AUTO OFF
ON - OFF
AUTO ON
