- If the monitor enters standby mode due to a rise in

temperature, to return to normal display, turn the power

switch off and then back on again. The monitor, however,

will enter standby mode again if the cause of the

temperature rise is not eliminated. (See page 9.)

- Check whether the monitor is placed at a location where

a quick rise in temperature is likely. Internal temperature

rises quickly if the vents on the monitor are blocked.

- Internal temperature rises quickly if dust accumulates

inside the monitor or around the vents. Remove dust if

possible. Ask Sharp dealer about removing internal dust.
