Using Your Portable Speaker
Any of the eight paired devices can initiate a paired connection to the speaker.
The speaker will automatically initiate a paired connection (when powered on)
only with the last device it was connected to. If you want to connect the
Portable Speaker 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 speaker afterwards, then becomes the "last connected"
device.
Note: If you power up your phone after turning on the portable speaker, then
you may initiate a connection to the last connected device by pressing the
MFB.
Note: Some phones request authorization upon each connection. You may
be able to disable this feature. Refer to your phone's user's guide for details.
