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. Especially fully ventilate in the vertical direction.
PAGE 90
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. (1) Hazardous voltage exists in the monitor. When removing the cover to work in the equipment, be sure to observe general electrical cautions. (2) Before removing or replacing PCB (module) and parts, turn OFF the power.

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. A set of dots emits light of red, green and blue depending on color signal intensity to reproduce every possible color. 6.4.
PAGE 92
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. To release stop of the protection mode, the power needs to be turned OFF and then ON. 6.4.3.
PAGE 93
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. It needs not to press continuously. Also, when turning ON the power, degaussing is automatically effected. 6.4.

Section 9 Maintenance 9.1 Fan Filter Every day Once a week Once a month Others Clean the dust-proof air filter at the air inlet of power unit located at the bottom front of equipment. If the filter is choked, the breaker may be cut off or the power unit may possibly be damaged. NOTE: • Be sure to turn OFF the power before cleaning the filter. • Never turn ON the power unless mounting the filter. Dust around the power unit may enter into it causing a fire. 9.2 Other Maintenance Items 1.

4. Monitor Every day Once a week Once a month Others (1) Before cleaning the monitor, turn OFF the power to the main unit and extract the power cable from the power outlet. (2) Use cloth supplemented to the equipment to clean the surface of monitor. Use soft cloth and glass cleaner to wipe off any sticky stains. Use cloth moistened with a neutral detergent to clean the top and side faces of monitor cover, and then wipe off them with soft cloth. NOTE: • Never use organic solvent such as thinner.
