� If the screen monitor turns off and self-diagnostic lamps light or flash
If the self-diagnostic lamps light or flash in red, check the following before consulting the dealer where you purchased the Monitor. � If self-diagnostic lamp 1 (upper) flashes, lamp 2 (middle) lights, and lamp 3 (lower) flashes This may be caused by the dusty intakes on the rear. If this happens, switch off the main power by POWER switch (set to �� (off)�), unplug the AC power cord, then clean the intakes by referring to the instruction on page 2. � After cleaning, switch on the Monitor�s main power again. If self-diagnostic lamps do not go off, consult your dealer immediately.

Note: If you switch on the main power immediately after switching it off (or after recovering from a brief power interruption), the self-diagnostic lamps may light (or flash), and no image may appear on the screen. In this case, switch off the main power again, wait for about 10 seconds, then switch it on again. If no self-diagnostic lamps light or flash, you can operate and use the Monitor as usual.

� If the screen monitor dims a little and �TEMP. OVER� lights (or flashes)
If �TEMP. OVER� lights or flashes at the right bottom of the screen, check the following before consulting the dealer where you purchased the Monitor. �TEMP. OVER� appears to warn you of the internal heat buildup, which is usually caused by accumulated dust around the intakes or by improper installation. If the cause of the internal heat buildup is eliminated, this indication disappears and the screen recovers the brightness. � If �TEMP. OVER� flashes in yellow This may be caused by the dusty intakes on the rear. If this happens, switch off the main power by POWER switch (set to �� (off)�), unplug the AC power cord, then clean the intakes by referring to the instruction on page 2. � After cleaning, switch on the Monitor�s main power again. If �TEMP. OVER� still flashes, this trouble may be caused by improper installation or improper location of the Monitor. In this case, consult your dealer immediately to solve this improper installation and to improve the circumstances around the Monitor. � If �TEMP. OVER� lights in red �TEMP. OVER� will be shown for abut two minutes, the Monitor will shut off automatically, then the Selfdiagonal lamps light in red. If this happens, switch off the main power by POWER switch (set to �� (off)�), unplug the AC power cord, then consult your dealer immediately.
