NFC Card Usage

There are typically 3 cards: a blue main card and a white secondary card. The blue main card acts as the master, while the white sub-card is for guests. The premise for using the blue main card is that P96 is set to 1 or 2. Short press the boot button (within 5 seconds) and swipe the blue main card in the NFC area. The number '1' will appear. Swipe the first white card for '1', the second for '2', and the third for '3'. If a third white card is swiped, the instrument shuts down. Each swipe produces a beep. Press the power button to swipe the white card to turn on.
