Just this morning my “three” key (above the W and E, not numeric keypad) stopped working, both with and without shift pressed. I have tried putting the keyboard into and out of demo mode, disconnecting and reconnecting, and rebooting.
All other keys appear to work.
Model RZ0-0204
P/N RZ0-02041800-RU1
I can share video on PM.
Anyone have any advice?
