Fixed Keys
The three round keys below the soft keys each have a fixed
function. The first key is the ON/OFF key, the middle key is EXIT
and the last key is ENTER.
The ON/OFF key is used to both turn power on to the 2020 as well
as turn the power off. To turn on 2020, press the ON/OFF key. To
turn the power off, press the ON/OFF key and hold it down for 2
seconds, and then release it. This is done to prevent accidental
power off.
