Using Your Headset
Paired Link to Additional Devices
Your headset can store pairing information for up to eight different devices equipped
with Bluetooth wireless technology. Devices are stored in a "Paired Device List" in
memory in chronological order. When an attempt to pair to more than eight devices
is made, the oldest paired device is removed from the list.
Any of the eight paired devices can initiate a paired connection to the headset.
The headset will only automatically initiate a paired connection (via opening the
boom) with the last device it was connected to . If you want to connect the
headset to another device in the paired device list, you must initiate the connection
from that device. Whichever of the eight devices initiates a connection to the headset
afterwards, that device then becomes the "last connected" device.
