Below is the procedure for activating Bluetooth.It works on all my speakers.

1. Switch on the Projector

2. Press and hold the Menu-Button for 8 sec.

3. Press the ESC-Button twice.
Now a new Window with Information about the PJ appears. With the
"Arrow-right" and "Arrow-left"-Button you can see several other Information Windows.

4. Press again the Menu-Button for 8 sec.

5. Press again the ESC-Button twice.

Now a new Windows appears.
On the left side you see 8 lines named "DIP-SW1" to "DIP-SW 8".
To enable BT menu set DIP-SW 7 BIT 2 from 0 to 1.

6. Restart PJ

7. Go to Menu -> Settings -> Bluetooth to enable this option.
