# XVI.	Parameters

Here is a list of parameters preprogrammed in your instrument in order to improve its use and its operating time:

·        Flight tracks <mark style="color:red;">**less than a minute**</mark> long will be automatically deleted by the SYS PC Tool

·        When flying, your instrument will automatically stop recording the flight if **neither a ground speed or a vario** is detected, unless you’ve manually forced the recording see chapter V.

·        Your instrument will automatically turn OFF if a <mark style="color:red;">**20 minutes**</mark> inactivity is detected, unless you’re flying.

·        **Time and date** are set up thanks to the GPS (to get the GMT time) and your computer (to apply the timezone). In order to correctly set the time, connect your device to Sys’PC tool.
