I tried to look it up: https://fccid.io/NOIKBN249/Internal-Photos/Internal-Photos-3802584.pdf Page 4 might be interesting. Something below that 3d code (zbarimg does not recognize it) Peeling up the label reveals: TT21000 -44LQI 1802 TWN 6491U0 (two illegible characters) You find it in the net:=20 https://www.digipart.com/part/TT21000-48LQI36T Regards, Andreas
