Power ON/OFF:
Touching this symbol will either turn on or off the unit. When unit is on (power cable connected), the symbol is
not illuminated until the unit has been turned on once, then symbols will illuminate in white color. When unit is off
(power cable still connected) after it was previously turned on, the symbol is illuminated in white color (you can even
use the (-) and (+) to adjust the intensity of the illuminated symbols when in this state). When no power cable is
connected, no symbols will be illuminated. Please note that in some cases, the unit may be configured to alternative
power behaviour, see table below.
Note that when you turn off the unit, the Operating System (OS) will initiate its power shut down cycle, where
additional tasks such as exiting software will be performed automatically for some seconds before the unit eventually
is turned off.
