Operation
Important:
You can play audio from an audio device that sends its signal over a Bluetooth connection (e.g.,
smartphones, tablet computers, etc.). BT4.0 uses Bluetooth CSR 4.0 and has range of up to 30
feet (10 meters).
Once you "pair your Bluetooth device with BT4.0, they are "connected wirelessly. You can play
audio on your Bluetooth device, and it will be sent out of BT4.0's SPEAKERS output.
BT4.0 will not receive audio from a phone call. While using it, we recommend disabling your
cellular connection, if possible.
Do not use BT4.0 near a microwave oven, which can interfere with the reception.
While PA-20B/PA-20HB is paired with a Bluetooth device, over Bluetooth devices cannot pair to it.
You must unpair ("disconnect") the current Bluetooth device from BT4.0 to make it available
others.
