Night mode
1. Enable: Activate or deactivate the feature.
The brightness auto-adjust function will be activated
automatically if it has not already been set.
2. In screensaver: select this option to activate night mode
only while the screensaver is on.
3. Threshold: set the ambient light threshold. Night mode
will be activated below this threshold.
Increase or decrease the threshold (0-9).
When night mode is activated, all the lights (LEDS and
display) of the desk phone in idle state are turned off
as soon as the ambient light drops below a defined
threshold. The threshold represents the brightness of
the room (facing the screen) when your desktop phone
switches to night mode (0 = very dark, 9 = very bright).
In other words, if the threshold is low, the desk phone
will switch to night mode when the room is very dark.
Conversely, if the threshold is high, it will switch to
night mode when the room is still bright.
