Recommended Use - continued To avoid or minimize image retention: Like all phosphor-based display devices and all other gas plasma displays, plasma monitors can be susceptible to image retention under certain circumstances. Certain operating conditions, such as the continuous display of a static image over a prolonged period of time, can result in image retention if proper precautions are not taken. To protect your investment in this plasma monitor, please adhere to the following guidelines and recommendations for minimizing the occurrence of image retention: • Always enable and use your computer's screen saver function during use with a computer input source. • Display a moving image whenever possible. • Change the position of the menu display from time to time. • Always power down the monitor when you are finished using it. OPERATING ENVIRONMENT Operating environment temperature and humidity: 0 °C to +40 °C (+32 °F to +104 °F); less than 80%RH (cooling vents not blocked) Do not install this unit in a poorly ventilated area, or in locations exposed to high humidity or direct sunlight (or strong artificial light) WARNING Not for use in a computer room as defined in the Standard for the Protection of Electronic Computer/Data Processing Equipment ANSI/NFPA 75. NOTE: Please use shielded video signal cable, 15-pin mini D-SUB to 15-pin mini D-SUB with ferrite cores on both ends (not included). To reduce the likelihood of image retention from long-term use: • Lower the Brightness and Contrast levels as much as possible without impairing image readability. • Display an image with many colors and color gradations (i.e. photographic or photo-realistic images). • Create image content with minimal contrast between light and dark areas. Use complementary or pastel colors whenever possible. • Avoid displaying images with few colors and distinct, sharply defined borders between colors. Plasma monitor driving sound • The panel of the Plasma monitor is composed of extremely fine pixels and these pixels emit light according to received video signals. This principle may cause you to hear a buzz or electrical hum coming from the Plasma monitor. Also note that the rotation speed of the cooling fan motor increases when the ambient temperature of the Plasma monitor becomes high. You may hear the sound of the motor at that time. NOTE: The following items are not covered by the warranty. • Image retention • Panel generated sound. Examples: Fan motor and electrical noises circuit humming /glass panel buzzing. English-5
