IMPORTANT SERVICE NOTES
If there is a possibility that the high voltage fluctuates as a result of the repairs, never forget to check for such high voltage after the work.
Maintenance and repair of this receiver should be done bydischarging the high voltage completelythan 28.0 kV (at beam 0 kV (at beam 1,100 to the above-mentioned high voltage.may cause excess X-ray radiation.hardware is not lodged between the chassis and other metal parts in the receiver.fishpapers, cabinet backs, adjustment and compartment covers or shields, iso- lation resistor-capacity networks, mechanical insulators and etc.
SERVICING OF HIGH VOLTAGE SYSTEM AND PICTURE TUBEWhen servicing the high voltage system, remove static charge from it by connecting a 10k ohm Resistor in series with an insulated wire (such as a test probe) between picture tube dag and 2nd anode lead. (AC line cord should be disconnected from AC outlet.)1.Picture tube in this receiver employs integral implosion protection. 2.Replace with tube of the same type number for continued safety. 3.Do not lift picture tube by the neck. 4.Handle the picture tube only when wearing shatterproof goggles and afterX-RAYThis receiver is designed so that any X-Ray radiation is kept to an absolute minimum. Since certain malfunctions or servicing may produce potentially hazardous radiation with prolonged exposure at close range, the following precautions should be observed:1. When repairing the circuit, be sure not to increase the high voltage to more2. To keep the set in a normal operation, be sure to make it function on 25.0 kV 3.Do not substitute a picture tube with unauthorized types and/or brands whichBEFORE RETURNING THE RECEIVERBefore returning the receiver to the user, perform the following safety checks.1.Inspect all lead dress to make certain that leads are not pinched or that2.Inspect all protective devices such as non-metallic control knobs, insulating
