SAFETY PRECAUTION

GENERAL GUIDE LINES

1. 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, replace all parts that have been overheated or damaged by the short circuit.
3. After servicing, see that all the protective devices such as insulation barriers, insulation papers, shields and isolation R-C combinations are correctly installed.
4. When the receiver is not being used for a long period of time, unplug the power cord from the a.c. outlet.
5. Potentials as high as 30kV are present when this receiver is in operation. Operation of the receiver without the rear cover involves the danger of a shock hazard from the receiver power supply. Servicing should not be attempted by anyone who is not familiar with the precautions necessary when working on high voltage equipment. Always discharge th, anode of the tube.
6. After servicing make the following leakage cyrre checks to prevent the customer from being expose to shock hazard.

LEAKAGE CURRENT COLD CHECK .

1. Unplug the a.c. cord and connect a‘jumper etween the two prongs of the plug.
2. Tum on the recsiver’s power SWitch.
3. Measure the resistance value with an ohmmeter, between the jumpéeted ac. plug and eacii exposed metallic cabinet part on the rceiver, such as screw heads, aerials, connectors control shafts etc. When the exposed metallic part has a rutum path to the chassis, the reading ‘should be between 4M ohm and 20M ohm. When the exposed metal does not have a retum path to the chassis, the reading must be infinite.

LEAKAGE CURRENT HOT CHECK

1. Plug the a.c. cord directly into the a.c. outlet. Do not use an isolation transformer for this check.
2. Connect a 2kOQ 10W resistor in series with an exposed metallic part on the receiver and an earth, such as a water pipe.
3. Use an ac. voltmeter with high impedance to measure the potential across the resistor.
4. Check each exposed metallic part and cheek the voltage at each point.
5. Reverse the a.c. plug at the outlet and repeat each of the previous measurements..
6. The potential at any point should hot exceed 1,4 Vrms. In case a measurement is outside the limits specified, there is a possibility-of a shock hazard, and the recever should be repaired and rechecked before it is returnd to the customer.

X-RADIATION WARNING

1. 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 without causing X-Radiation.

NOTE: It is important to use an accurate periodically calibrated 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, immediate service and correction is required to prevent the possibility of premature component failure.

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