5. PowerSensor™ 5. PowerSensor™ 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 upto 70%. User present in front User not present 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. Hot key Sensor distance 3 Landscape/Portrait mode Watt ATTENTION PowerSensor off ATTENTION PowerSensor off Power consumption as illustrated above is for reference purpose only Setting Default settings 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 five 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 efficiency: The higher the setting, the stronger the detection signal. For maximum PowerSensor efficiency 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 Above illustrations are for reference purpose only, may not reflect the exact display of this model. 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 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. 15
