# XIII.	Suggestion of use

* Use the strap to <mark style="color:red;">**secure**</mark> your instrument while flying.
* If the Alti is very hot and you fly in very cold air, **fog** can appear on the screen. It will dissipate within minutes.
* Only use the **backlight** if required. Otherwise the autonomy will decrease significantly.
* **A factory reset** from SYS PC Tool (Settings icon ![](/files/wZTHoxZlbYYKXAygSAPB) Repair) allows you to get your instrument back to default state (every recorded flight will be deleted).
* When you connect your instrument to a USB charger, the battery will start charging, even if the instrument is turned-off.
* Feel free to customize your screens thanks to the SSC Tool: <http://www.syride.com/en/ssctool/Alti>
