Q How does it work?
•
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%.

Q Setting
Default settings
At its default setting, (Setting 3), PowerSensor
is designed to detect the presence of the user
located between 30 and 100 cm (12 and 40
inches) from the display and within fve degrees
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
signal for optimal detection effciency:The higher
the setting, the strongerthe detection signal. For
maximum PowerSensoreffciencyand proper
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 120cm 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.
You can return to the default mode at any
time (setting 3)

remain operational unless and until it is readjusted
orthe default mode is recalled. If you fnd that
the PowerSensor is excessively sensitive to nearby
motion for some reason, please adjustto a lower
signal strength.
