Input Change

Pressing key 1 to 8 briefly will switch the input selection to the corresponding SCART input.


Functions

Holding 1/Shift for longer than half a second and the "SHIFT" text will start to glow yellow. Then you can tap the other function keys while keeping 1 pressed - works just like the Shift key on a keyboard.

Alternatively, you can also press 1/Shift and the function you wish to trigger at the same time after you got familiar with the keypad.

Hidden Key Combinations

These commands are input by letting go of the indicated keys together. You don't have to press them down at the same time.

- System Reboot: 2 + 7

- Invert Screen: 3 + 6

- Change LED Color Scheme: 4 + 5


Icon Customization Mode

Holding any key for longer than 2 seconds will trigger the icon customization mode for the corresponding input number.
