S/M Code No. 09-009-352-0N1 DA TA NOTICES BEFORE REPAIRING To make the best use of this equipment, make sure to obey the following items when repairing (or mending). 1. Do not damage or melt the tunicate of the leading wire on the AC1 side, including the power supply cord. 2. Do not soil or stain the letters on the spec. inscription plates, notice labels, fuse labels, etc. 3. When repairing the part extracted from the conducted side of the board pattern, fix it firmly with applying bond to the pattern and the part. 4. Restore the following items after repairing. 1) Conditions of soldering of the wires (especially, the distance on the AC1 side). 2) Conditions of wiring, bundling of wires, etc. 3) Types of the wries. 4) Attachment conditions of all types of the insulation. 5. After repairing, always measure the insulation resistance and perform the voltage-withstand test (See Fig-1). 1) The insulation resistance must be 7.3 M to 10.1 M when applying 500V per second. 2) In the voltage withstand test, apply 3.0 kV for 1 minute and check that the GO lamp lights. * * * * Breaking current set to 10 mA. Connect the safety checker as shown in Fig-1, then measure the resistance and perform the test. Do not touch the equipment during testing. For details of the safety checker, refer to the supplied Operation manual. Insulation resistance: 7.3 M to 10.1 M(500 V/s) Voltage-withstand: 3.0 kV for 1 minute Safety checker (Model 7110, etc.) Earth cable AC cable Connect the earth cable to the outside metal part terminal. Fig-1 When servicing and checking on the TV, note the followings. 1. Keep the notices As for the places which need special attentions, they are indicated with the labels or seals on the cabinet, chassis and parts. Make sure to keep the indications and notices in the operation manual. 2. Avoid an electric shock. There is a high voltage part inside. Avoid an electric shock while the electric current is flowing. 3. Use the designated parts. The parts in this equipment have the specific characters of incombustibility and withstand voltage for safety. Therefore, the part which is replaced should be used the part which has the same character. Especially as to the important parts for safety which is indicated in the circuit diagram or the table of parts as a ! mark, the designated parts must be used. 4. Put parts and wires in the original position after assembling or wiring. There are parts which use the insulation material such as a tube or tape for safety, or which are assembled so that these parts do not contact with the printed board. The inside wiring is designed not to get closer to the pyrogenic parts and high voltage parts. Therefore, put these parts in the original positions. 5. Take care of the cathode-ray tube. By setting an explosion-proof cathode-ray tube is set in this equipment, safety
