KEEP THE NOTICES 6. AVOID AN X-RAY 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. Safety is secured against an X-ray by considering about the cathode-ray tube and the high voltage peripheral circuit, etc. Therefore, when repairing the high voltage peripheral circuit, use the designated parts and make sure not modify the circuit. Repairing except indicates causes rising of high voltage, and it emits an X-ray from the cathode-ray tube. 2. AVOID AN ELECTRIC SHOCK There is a high voltage part inside. Avoid an electric shock while the electric current is flowing. 7. PERFORM A SAFETY CHECK AFTER SERVICING 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. Confirm that the screws, parts and wiring which were removed in order to service are put in the original positions, or whether there are the portions which are deteriorated around the serviced places serviced or not. Check the insulation between the antenna terminal or external metal and the AC cord plug blades. And be sure the safety of that. 4. PUT PARTS AND WIRES IN THE ORIGINAL POSITION AFTER ASSEMBLING OR WIRING (INSULATION CHECK PROCEDURE) 1. Unplug the plug from the AC outlet. 2. Remove the antenna terminal on TV and turn on the TV. 3. Insulation resistance between the cord plug terminals and the eternal exposure metal [Note 2] should be more than 1M ohm by using the 500V insulation resistance meter [Note 1]. 4. If the insulation resistance is less than 1M ohm, the inspection repair should be required. There are parts which use the insulation material such as a tube or tape for safety, or which are assembled in the condition that these 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 TO DEAL WITH THE CATHODE-RAY TUBE [Note 1] In the condition that an explosion-proof cathode-ray tube is set in this equipment, safety is secured against implosion. However, when removing it or serving from backward, it is dangerous to give a shock. Take enough care to deal with it. If you have not the 500V insulation resistance meter, use a Tester. [Note 2] External exposure metal: Antenna terminal Earphone jack A-2 VCR TEST TAPE INTERCHANGEABILITY TABLE There are two types of the new alignment tape CH-1B (for NTSC) and CH-2 (for PAL).

NOTE * After turning the power off there might still be a potential voltage that is very dangerous. When removing the Anode Cap, make sure to discharge the Anode Cap's potential voltage. * Do not use pliers to loosen or tighten the Anode Cap terminal, this may cause the spring to be damaged. Take care not to damage the Rubber Cap. INSTALLATION 1. Clean the spot where the cap was located with a small amount of alcohol. (Refer to Fig. 3-3.) REMOVAL Location of Anode Cap 1. Follow the steps as follows to discharge the Anode Cap. (Refer to Fig. 3-1.) Connect one end of an Alligator Clip to the metal part of a flat-blade screwdriver and the other end to ground. While holding the plastic part of the insulated Screwdriver, touch the support of the Anode with the tip of the Screwdriver. A cracking noise will be heard as the voltage is discharged. Fig. 3-3 GND on the CRT NOTE Confirm that there is no dirt, dust, etc. at the spot where the cap was located. 2. Arrange the wire of the Anode Cap and make sure the wire is not twisted. 3. Turn over the Rubber Cap. (Refer to Fig. 3-4.) CRT Screwdriver Support Alligator Clip GND on the CRT Fig. 3-4 Fig. 3-1 4. Insert one end of the Anode Support into the anode button, then the other as shown in Fig. 3-5. 2. Flip up the sides of the Rubber Cap in the direction of the arrow and remove one side of the support. (Refer to Fig. 3-2.) Rubber Cap CRT CRT Support Support Fig. 3-5 Fig. 3-2 5. Confirm that the Support is securely connected. 6. Put on the Rubber Cap without moving any parts.

If the heads are not completely dry and alcohol gets on the tape, damage may occur. Wrap a piece of chamois around your finger. Dip it in isopropyl alcohol. Hold it to the cylinder head softly. Turn the cylinder head counterclockwise to clean it (in the direction of the arrow). (Refer to the figure below) 1. AUDIO CONTROL HEAD NOTE Wrap a piece of chamois around your finger. Dip it in isopropyl alcohol and clean the audio control head by wiping it horizontally. Clean the full erase head in the same manner. (Refer to the figure below) Do not exert force against the cylinder head. Do not move the chamois up or down since this can damage the head. Always use a piece of chamois for cleaning. Cylinder Head Audio Control Head 2. TAPE RUNNING SYSTEM When cleaning the tape transport system, use the gauze moistened with isopropyl alcohol. C2-1 NOTE FOR THE REPLACING OF MEMORY IC If a service repair is undertaken where it has been required to change the MEMORY IC, the following steps should be taken to ensure correct data settings while making reference to TABLE 1. NOTE • Initial Data setting will not be possible if clock has been set. To reset clock, either unplug AC cord and allow at least 30 minutes before Power On or alternatively, discharge backup capacitor. • No need the setting for after INI 6.
