CHAPTER 1 GENERAL ADJUSTMENTS X-RAY RADIATION PRECAUTION 1. Excessive high voltage can produce potentially hazardous X-RAY RADIATION. To avoid such hazards, the high voltage must not be above the specified limit. The nominal value of the high voltage of this receiver is (A) kV at zero beam current (minimum brightness) under a 120V AC power source. The high voltage must not, under any circumstances, exceed (B) kV. Refer to table-1 for high voltage (A), (B). (See SETTING & ADJUSTING DATA on page 26) 2.
GENERAL ADJUSTMENTS CRT ASSEMBLY REPLACEMENT AND MOUNTING CAUTION : DO NOT LOOSEN THE HEX HEAD BOLTS WITH SPRINGS (12 PCS), BECAUSE THOSE ARE FOR SEALING OF CRT COOLANT. R G B Attention Serviceman The Hex Head Bolts with Springs. (see sketch) used on CRT assembly, are “NOT” Adjustment Screws DO NOT LOOSEN-FLUID LEAKAGE WILL OCCUR.
