Power Button

Press this button (Fig. 10, pos. 1) to switch the system on or off.

Prerequisite:
The KBox A-101 has to be connected to an appropriate main power supply (DC).

Even when the system is turned off via the power button there is still a standby voltage of 5 VSb on the
SBC.
The unit is only completely disconnected from the DC mains, when the power cord is disconnected either
from the mains or the unit. Therefore, the power cord and its connectors must always remain easily
accessible.
