Image persistence • Please be aware that Plasma Technology may experience a phenomena known as Image Persistence. Image Persistence occurs when a residual or "ghost" image of a previous image remains visible on the screen. Unlike CRT monitors, Plasma monitors' image persistence is not permanent, but constant images being displayed for a long period of time should be avoided. To alleviate image persistence, turn off the monitor for as long as the previous image was displayed. For example, if an image was on the monitor for one hour and a residual image remains, the monitor should be turned off for one hour to erase the image. NOTE: As with all personal display devices, NEC DISPLAY SOLUTIONS recommends displaying moving images and using a moving screen saver at regular intervals whenever the screen is idle or turning off the monitor when not in use. RS-232C does not work • Check the PROTOCOL SET in the OPTION2 menu. Remote Control does not work • Make sure the batteries are inserted properly. • Test the batteries for strength/life. • Make sure to point the remote directly at the sensor on the monitor. • Check if the remote is in Remote ID mode. • The remote control may not function when in direct sunlight or when there is strong illumination on the remote sensor of the monitor. • Check the IR REMOTE setting in the OPTION3 menu. Image is unstable, unfocused or swimming is apparent • Signal cable should be properly attached to the Plasma monitor, computer, or other input device. • Use the OSD screen controls to focus and adjust display by increasing or decreasing the clock phase total. When the display mode is changed, the OSD Image Adjust settings may need to be readjusted. • Check the monitor and your display card with respect to compatibility and recommended signal timings. Image of component signal is greenish • Check to see if the DVD/HD input connector is selected.
