BT PRO prompts you to choose GROUP CHECK mode. To en-
ter GROUP CHECK mode, press the marking button when the GROUP CHECK pictogram is blinking on the screen.
In this mode, you can test your partners' devices one after
another by positioning your device 1 m away from each de-
vice to be checked. It is imperative you stay 1 m away for the
GROUP CHECK to work properly; if you do not, the device will
inform you that you are too close or too far away with repeat-
ed "double beeps".

that the device being checked is defective and must be taken
care of by our after-sales service.
