How does it worN"
 PowerSensor works on principle of
transmission and reception of harmless
“infrared” signals in order to detect
userpresence.
 When the user is in front of the monitor
the monitor operates normally, at the
predetermined settings that the user has set -
i.e. Brightness, Contrast, Color, etc.
 Assuming that the monitor was set to 100%
of brightness for example, when the user
leaves his seat and is no longer in front of the
monitor, the monitor automatically reduces
the power consumption up to 80%.

Default settings
PowerSensor is designed to detect the presence of
the user located between 30 and 100 cm (12 and

left or right of the monitor.
Custom settings
If you prefer to be in a position outside the
perimeters listed above, choose a higher strength

the setting, the stronger the detection signal. For
PD[LPXP3RZHU6HQVRUHIÀFLHQF\DQGSURSHU
detection, please position yourself directly in front
of your monitor.
 If you choose to position yourself more than
100 cm or 40 inches from the monitor use
the maximum detection signal for distances
up to 120 cm or 47 inches. (Setting 4)
 Since some dark colored clothing tends to
absorb infrared signals even when the user
is within 100 cm or 40 inches of the display,
step up signal strength when wearing black or
other dark clothes.

the PowerSensor is excessively sensitive to nearby
motion for some reason, please adjust to a lower
signal strength.
