6.3 Installation 6.3.1 Cautions in installing the monitor Convergence of the color monitor is affected from external induction magnetic field. Avoid installing the equipment in any region where induction magnetic field exists. Also observe the following cautions to obtain stable performance for a long period of time. (1) Ventilation To obtain stable performance for a long period of time, keep temperature inside the cabinet below 50ºC.
Page 90: Cautions For Safety
To remove this dust periodically, use soft cloth moistened with silicone type glass cleaner. Never use thinner or the like instead of the cleaner. 6.3.2 Cautions for safety NOTE: Observe all the cautions and notices concerning safety labeled on the chassis or CRT. Hazardous voltage exists in the monitor.

The 3-beam electron gun is arranged in line, so section of three electron beams is arranged in line horizontally. Three electron beams emitted from the electron gun are deflected to scan whole fluorescent screen. Electron beam is blocked off by the shadow mask and hits fluorescent material only corresponding to each color when it passes through the hole.
Page 92: Video Board (Avb411)
High voltage is adjusted by VR105, and stabilized by switching of transistor (Q120) and control circuit (IC108). If high voltage increases abnormally in any trouble, the high voltage protection circuit (IC107) controls high voltage to reduce +B voltage, and stops switching of the horizontal AFC circuit (IC110) to stop output.

6.4.4.3 NTSC/PAL signal detection circuit Converts frequency of NTSC (fv: 60Hz) and PAL (fv: 50Hz) to voltage by the F/V converter (IC301), and compares the voltage by the comparator (IC302) to output switchover signals. 6.4.4.4 Degauss control circuit The degauss switch is a momentary type. Once it is pressed, degaussing is kept for about 10 seconds.
