*Note 1:
Numeric entry will is only displayed when a K81 requires it. If the numeric entry
screen is shown when user UI is live, a numeric entry is kept until the user updates the UI. If
the numeric entry screen is shown on the system UI while it is live, a numeric entry is closed
after the end of the numeric entry session.
•
*Note 2:
If the device does not display a screen after a reset, quickly press the top-right
corner of the screen, then do a long press in the top-left corner to show the Settings menu.
•
*Note 3:
The area that detects press-and-hold events is 70px*70px and always at the top-
