changed. Though the remaining picture will disappear after a while, there may be a case that it remains
for a long period depending on the length of time the still image was displayed for. This is due to the
characteristics of the LCD display and is not a malfunction.

Contact your dealer with the information about which lamps are flashing.
• If you turn on the monitor soon after turning it off (or after a short-term power failure), the self-check lamps may
flash and no image may be displayed. When this happens, turn off power and wait at least 10 seconds before
turning on the monitor again. If the self-check lamps do not flash, you can use the monitor as normal.
