# II.	Turn ON and OFF the flight computer

It is important to know that compared to other displays, the one the SYS’Evolution is using does not require any power to keep an image displayed. This is why when you received it, some information may already be displayed on the screen!

1. To turn ON your flight computer, press the START button once. <mark style="color:red;">**A small red light turns-on in the eye of the eagle to indicate that the instrument is ON**</mark>.

The boot sequence lasts a few seconds to initialize all the sensors. The "**GPS booster**" is then activated to minimize the time of reception of the GPS signal. As soon as the reception is sufficient, the instrument will automatically switch to the flight screen.

2. The instrument will be automatically turned OFF after **20 minutes** of inactivity (no ground speed nor vario). To manually turn it OFF, press the START button during 2 seconds, until the display wipes out.
