    Using SMA Grid unlock codes

    Has anybody had to use the SMA grid code unlock system? Looking at the SB4000TL once the code has been entered say via sunny explorer, is it possible then to simply use the grid setting dials (A & B) on the inverter or does it have to be changed using sunny explorer.
