to the external power supply.
4.2.2 Key
Pressing the key allows showing/hiding the icons of the instrument's main menu
(operation possible also by touching the display), setting the value of the distance from the
object in Fusion screens (see § 5.1.3) and quitting the internal function screens and going
back to the main menu.
4.2.3 Key

pressing the key, or to let the instrument calibrate itself automatically after a certain set
time (see § 5.2.1.2).
4.2.4 Key
Press the key to automatically save the IR image shown on the display in the
instrument's memory (micro SD card) (see § 5.2.4.1).
