The Bluetooth can be powered down by pressing the Bluetooth key for longer than 3 seconds. It can then be “re-
powered” by pressing the Bluetooth key again.

While the Bluetooth unit is powered, a short press will put the Bluetooth in “pairing mode” and a cellphone, PC, or other
Bluetooth device can connect to the CHAT 150 BT. While in “pairing mode”, pressing the Bluetooth key will stop the
pairing mode.
If a device is already connected, pressing the Bluetooth key will “disconnect” that device but it will still be “paired”.

over the Bluetooth.
