① Infrared sensor
Infrared sensor for the optional wireless remote controller RCT-30A.
② NO BURST LED
LED which operates only when the composite signal input is selected.
The LED lights up when the selected composite signal has no burst (black and white
signal) or when the color killer circuit is activated.
③ OVERLOAD LED
This LED lights up when the ABL circuit is activated (the luminance is higher than
necessary).
Using the monitor in a way which causes this LED to light up continuously for a long
time will deteriorate the CRT. Therefore use the monitor with the luminance lowered.
④ DEGAUSS switch
When the power is turned ON, CRT demagnetization will be performed automatically.
This switch allows demagnetization to be performed at one-touch.
As pressing this switch continuously has no effect, release and press again 2 to 3
minutes later.
