[. . . ] 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. [. . . ] This is a unique Philips feature designed to preserve the life of your monitor. Please allow 5 seconds between powering off and on your monitor, your picture will then be restored. A microprocessor-based feature of Philips Brilliance monitors is able to detect automatically horizontal and vertical frequencies of input signals with those of the installed video card. An autoscan monitor can thus operate with a wide range of video cards. A special construction of connector used in some monitors with higher horizontal scanning frequency. The BNC connection can provide the optimum shielding and matching characteristic impedance of video signal path to ensure the best video performance. CE mark is displayed on products per EMC and LV ( low Voltage Device ) directives in compliance with European Community safety, EMI and EMS requirements and is compulsory on products for sale in the European Community. A way of describing the color of a radiating source in terms of the temperature (in degrees Kelvin) of a black body radiating with the same dominant frequency as the source. The ratio between the brightness of the brightest and darkest parts of a picture. The darkest part of a picture is set by the brightness of the unexcited phosphor, which is governed by the degree with which ambient light is reflected. Contrast is therefore reduced in conditions of high ambient light levels. The TCO standard is more severe since not only are the permitted field levels reduced compared with MPR-II, but the measuring distance is also reduced (see table). Electromagnetic radiation standards EMI (Electrical Magnetic Interference) The electrical and/or magnetic radiation coming from the working electrical or electronic equipment. Very rapid variations in picture intensity caused by the finite time required for the electron beam to scan a picture onto the screen. Two kinds of flicker occur: line flicker caused by the electron beam scanning-in each line of the picture; and frame flicker (or field flicker if the picture is interlaced) caused by the frame repetition rate of 50 frames/second. Frame flicker is noticeable with GUI and DTP software (which have a light background), and can be very disturbing, especially for those who work regularly with displays - contributing to eye strain, headaches, visual blurring, stress, etc. The problem can, however, be eliminated by increasing the refresh rate (number of frames/second) of the monitor to a value above around 70 Hz. The unit of frequency named after the physicist Heinrich Hertz (1857-1894). Also called line frequency and expressed in kHz, it is the number of video lines written on the screen every second (from left to right). The higher the horizontal scanning frequency, the better the resolution (i. , the higher the resolution and/or the higher the refresh rate). The set-up functions retrieve information from the INF file to use when performing installation operations. [. . . ] 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. [. . . ]
