Can I disable the front keys, keyboard, mouse and/or touch screen on the ENA / ENA-L?

(SUPPORTED MODELS IN BOLD: E5071C E5070B/71B E5070A/71A E5061A/62A E5061B E5072A) Yes. Under [System] > [Misc. Setup] > [Key Lock] menu, you can select "Front Panel & Keyboard Lock" and "Touch Screen & Mouse Lock". You cannot use a locked device to unlock that same device. To unlock the front panel keys, keyboard, touch screen and mouse that have been locked, press the Standby switch to turn off the power supply and then turn it on again. When setting at power-on, the front panel keys, keyboard, touch screen and mouse are all in an unlocked condition.
