2. First Steps
2.1 Switching on
The CORE is switched on by holding the -Tbutton pressed in until it lights up red. Release the button briefly, then confirm the
power-on process by briefly pressing the button a second time. The transmitter is switched off in exactly the same way. The
button changes to green when the Linux system has booted; this process takes about 25 seconds. Once the CORE is running,
you will see the Home display on the screen: this shows fields containing telemetry values, timers, servo positions or quick-select
buttons for menus. These fields are known as widgets.
2.2 Entering the menu
The main menu is accessed by swiping a finger downwards from the top edge. You can now touch the left-hand menu symbol :
There is no need to press firmly, as the capacitive touch-screen simply responds to touch, like all modern smartphones. The sym-
bols in the Main menu are arranged in order of importance.
The CORE is fitted with a fully redundant power supply system, which is deliberately kept separate from the Linux computer
and the other processors. This means than any malfunctions in the complex Linux system cannot possibly result in the trans-
mitter switching itself off. The two real-time processors also function completely independently of the Linux computer. The
model remains fully controllable even if the Linux computer is pulled out when the system is running!
