is present).

4. Laser
This function switches the laser pointer on and off.

1.5.5. Setting the time before automatic shutdown of the camera
To extend its battery life, the camera switches itself off automatically (no operator action: key press, etc.) after a time that can be
set to between 15 and 60 minutes (15min being the default value).
This function is accessible from the Main/Parameters/Adjustments menu, by validating the item opposite.
It is possible to deactivate this function (choose "None"), in which case the camera will switch itself off (if the operator does
nothing) when the batteries are too low to supply it.
1.5.6. Adjusting the brightness of the screen
For greater convenience of use, it is possible to adjust the screen lighting level. For example, the lighting can be lowered when it
is dark to avoid being dazzled, or turned up for use outdoors on a sunny day.
By default, the camera is configured in automatic mode: a luminosity sensor adjusts the lighting level at all times.
This adjustment, which directly affects the battery life, can be accessed from the Main/Parameters/Adjustments
menu by validating the item opposite.
