[. . . ] Do not place objects on top of the monitor cabinet, objects could fall into vents or cover them and prevent proper cooling of the monitor's electronic devices. To avoid the risk of shock or permanent damage to the set, do not expose the monitor to rain or excessive moisture. Do not use alcohol or ammonia-based liquid to clean the monitor. If necessary, clean with a slightly damp cloth. [. . . ] Because of the magnetic field of earth, the screen of monitor will be tilt when the screen faces toward the different direction. Anti-Static coatings Due to bombardment by beam electrons, monitor screens become electrically charged when in use. electrically charged screens surfaces can attract dust particles. An Anti-Static coating is a conductive coating deposited on the screen (or on a glass panel immediately in front of the screen) that conducts away the charge and prevents screen dust build-up. aGAS (Anti-Glare , Anti-Static) coating AGAS is a silica coating applied to the surface of the screen by a spinning and spraying process. It operates by diffusing reflected light to blur images of light sources on the screen. Anti-static properties are provided by a single conductive layer within the multi-layer structure. With ARAS, the intensity of reflected light is reduced from around 4. 5% of the incident light (the reflectivity of uncoated screens) to less than 0. ARAS also has a major advantage over other screen treatments: It doesn't diffuse or scatter reflected light, so picture contrast and sharpness remain completely unimpaired. It's also easy to clean and tough enough to withstand commercially available cleaning agents. The hub isolates low speed ports from full speed At the lowest level, device may refer to a single hardware component, as in a memory device. At a higher level, it may refer to a collection of hardware components that perform a particular function, such as a Universal Serial Bus interface device. At an even higher level, device may refer to the function performed by an entity attached to the Universal Serial Bus; for example, a data/FAX modem device. Downstream The direction of data flow from the host or away from the host. A downstream port is the port on a hub electrically farthest from the host that generates downstream data traffic from the hub. The monitor with UPS feature can work in different countries with various mains voltage. Expressed in Hz, this is the number of fields written to the screen every second in interlaced mode. In non-interlaced mode vertical scanning frequency is the number of frames (complete pictures) written to the screen every second (also known as refresh rate). A train of square shaped waveforms that define the start of a new frame. VESA was instrumental in the introduction of the Super VGA and Extended VGA video graphics standards (see Video graphics adapters) with a refresh rate of 70 Hz, minimizing flicker and helping to reduce operator eyes fatigue and stress. A card equipped with a character or graphic generator and video memory, which maps to the screen. [. . . ] In countries where Philips Consumer Electronics does not distribute the product, the local Philips service organization will attempt to provide service (although there may be a delay if the appropriate spare parts and technical manual(s) are not readily available). For more information, contact the Philips Customer Care Center by calling (877) 835-1838 (U. Please check your owner's manual before requesting service. Adjustments of the controls discussed there may save you a service call. [. . . ]
