    SAFETY PRECAUTIONGENERAL GUIDE LINES1. It is advisable to insert an isolation transformer in the

    a.c. supply before servicing a hot chassis.2. When servicing, observe the original lead dress in the

    high voltage circuits. If a short circuit is found, replaceall parts that have been overheated or damaged by the short circuit.

    3. After servicing, see that all the protective devicessuch as insulation barriers, insulation papers, shieldsand isolation R-C combinations are correctly installed.

    4. When the receiver is not being used for a long periodof time, unplug the power cord from the a.c. outlet.

    5. Potentials as high as 30kV are present when thisreceiver is in operation. Operation of the receiverwithout the rear cover involves the danger of a shockhazard from the receiver power supply. Servicingshould not be attempted by anyone who is notfamiliar with the precautions necessary when workingon high voltage equipment. Always discharge theanode of the tube.

    6. After servicing make the following leakage currentchecks to prevent the customer from being exposedto shock hazard.

    LEAKAGE CURRENT COLD CHECK1. Unplug the a.c. cord and connect a jumper between

    the two prongs of the plug.2. Turn on the receivers power switch.3. Measure the resistance value with an ohmmeter,

    between the jumpered a.c. plug and each exposedmetallic cabinet part on the receiver, such as screwheads, aerials, connectors, control shafts etc. Whenthe exposed metallic part has a return path to thechassis, the reading should be between 4M ohm and20M ohm. When the exposed metal does not have areturn path to the chassis, the reading must be infinite.

    LEAKAGE CURRENT HOT CHECK1. Plug the a.c. cord directly into the a.c. outlet. Do not

    use an isolation transformer for this check.2. Connect a 2k 10W resistor in series with an

    exposed metallic part on the receiver and an earth,such as a water pipe.

    3. Use an a.c. voltmeter with high impedance tomeasure the potential across the resistor.

    4. Check each exposed metallic part and check thevoltage at each point.

    5. Reverse the a.c. plug at the outlet and repeat each ofthe previous measurements.

    6. The potential at any point should not exceed1,4 Vrms. In case a measurement is outside the limitsspecified, there is a possibility of a shock hazard, andthe receiver should be repaired and rechecked beforeit is returned to the customer.

    X-RADIATION WARNING1. The potential sources of X-Radiation in TV sets are

    the high voltage section and the picture tube.2. When using a picture tube test jig for service, ensure

    that the jig is capable of handling 30kV withoutcausing X-Radiation.

    NOTE: It is important to use an accurate periodicallycalibrated high voltage meter.1. Set the brightness to minimum.2. Measure the high voltage. The meter should indicate:

    29kV 1kV.If the meter indication is out of tolerance, immediateservice and correction is required to prevent thepossibility of premature component failure.

    3. To prevent any X-Radiation possibility, it is essentialto use the specified tube.
