4. PowerSensor™
(Available for 231P4QPY & 231P4QPYK)
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%.
User present in front User not present
Power consumption as illustrated above is for reference purpose only
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 ve 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 efciency:
The higher the setting, the stronger the
detection signal. For maximum PowerSensor
efciency and 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 120 cm or 47 inches.
