How does it work?

‡

PowerSensor works on principle of
transmission and reception of harmless
“infrared” signals in order to detect user-
presence.

‡

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 down to
80%.

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

left or right of the monitor.

Custom settings

If you prefer to be in a position outside the
perimeters listed above, choose a higher

The higher the setting, the stronger the
detection signal. For maximum PowerSensor

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.

‡

You can return to the default mode at any
time (Setting 3).

How to adjust settings

If PowerSensor is not operating correctly
inside or outside the default range, here’s how
to fine-tune detection:

‡

Press the PowerSensor hot key

‡

You will find the default position ‘3’ on the
adjustment bar.

‡

Adjust the PowerSensor detection
adjustment to Setting 4 and press OK.

‡

Test the new setup to see if PowerSensor
properly detects you in your current
position.

‡

PowerSensor function is designed to work
in Landscape mode (horizontal position)
only. After PowerSensor turn on it, it will
automatically turn Off if the monitor is
used in Portrait mode (90 degree/vertical
position); it will automatically turn ON if
monitor is returned to its default Landscape
position.

Note

A manually selected PowerSensor mode
will remain operational unless and until it is
readjusted or the default mode is recalled. If
