IMPORTANT SAFETY NOTICE There are special components used in this equipment which are important for safety. These parts are marked by in the Schematic Diagrams, Circuit Board Layout, Exploded Views and Replacement Parts List. It is essential that these critical parts should be replaced with manufacturer's specified parts to prevent X-RADIATION, shock, fire, or other hazards. Do not modify the original design without permission of manufacturer. An Isolation Transformer should always be used during the servicing of AC Adaptor whose chassis is not isolated from the AC power line. Use a transformer of adequate power rating as this protects the technician from accidents resulting in personal injury from electrical shocks. It will also protect AC Adaptor from being damaged by accidental shorting that may occur during servicing. When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have been overheated or damaged by the short circuit. After servicing, see to it that all the protective devices such as insulation barriers, insulation papers shields are properly installed. After servicing, make the following leakage current checks to prevent the customer from being exposed to shock hazards. Leakage Current Hot Check (See Figure 1.) 2. 3. 1. Plug the AC cord directly into the AC outlet. Do not use an isolation transformer for this check. 2. Connect a 1.5 k, 10 W resistor, in parallel with a 0.15 F capacitor, between each exposed metallic part on the set and a good earth ground, as shown in Figure 1. 3. Use an AC voltmeter, with 1 k/V or more sensitivity, to measure the potential across the resistor. 4. Check each exposed metallic part, and measure the voltage at each point. 5. Reverse the AC plug in the AC outlet and repeat each of the above measurements. 6. The potential at any point should not exceed 0.75 V RMS. A leakage current tester (Simpson Model 229 or equivalent) may be used to make the hot checks, leakage current must not exceed 1/2 mA. In case a measurement is outside of the limits specified, there is a possibility of a shock hazard, and the equipment should be repaired and rechecked before it is returned to the customer. 4. 5. 1.2. Leakage Current Cold Check Figure. 1 1. Unplug the AC cord and connect a jumper between the two prongs on the plug. 2. Measure the resistance value, with an ohmmeter, between the jumpered AC plug and each exposed metallic cabinet part on the equipment such as screwheads, connectors, control shafts, etc. When the exposed metallic part has a return path to the chassis, the reading should be between 1 M and 5.2 M. When the exposed metal does not have a return path to the chassis, the reading must be infinity. 3 1.4. How to Discharge the Capacitor on Flash PCB CAUTION: 1. Be sure to discharge the capacitor on FLASH PCB. 2. Be careful of the high voltage circuit on FLASH PCB when servicing. [Discharging Procedure] 1. Refer to the disassemble procedure and Remove the necessary parts/unit. 2. Put the insulation tube onto the lead part of Resistor (ERG5SJ102:1k /5W). (an equivalent type of resistor may be used.) 3. Put the resistor between both terminals of capacitor on FLASH PCB for approx. 5 seconds. 4. After discharging confirm that the capacitor voltage is lower than 10V using a voltmeter. Fig. F1 4 2 Warning 2.1. Prevention of Electro Static Discharge (ESD) to Electrostatically Sensitive (ES) Devices Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Electrostatically Sensitive (ES) Devices. The following techniques should be used to help reduce the incidence of component damage caused by electro static discharge (ESD). 1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any ESD on your body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging ESD wrist strap, which should be removed for potential shock reasons prior to applying power to the unit under test. 2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as aluminum foil, to prevent electrostatic charge buildup or exposure of the assembly. 3. Use only a grounded-tip soldering iron to solder or unsolder ES devices. 4. Use only an antistatic solder removal device. Some solder removal devices not classified as "antistatic (ESD protected)" can generate electrical charge sufficient to damage ES devices. 5. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ES devices. 6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most replacement ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or comparable conductive material). 7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective material to the chassis or circuit assembly into which the device will be installed. CAUTION : Be sure no power is applied to the chassis or circuit, and observe all other safety precautions. 8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as the brushing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity (ESD) sufficient to damage an ES device). 2.2. How to Recycle the Lithium Ion Battery (U.S. Only) 5 2.3. 2.3.1. Caution for AC Cord (For EB/GC/SG) Information for Your Safety 2.3.2.1. Important The wires in this mains lead are coloured in accordance with the following code: Blue Brown Neutral Live IMPORTANT Your attention is drawn to the fact that recording of prerecorded tapes or discs or other published or broadcast material may infringe copyright laws. WARNING To reduce the risk of fire or shock hazard, do not expose this equipment to rain or moisture. CAUTION To reduce the risk of fire or shock hazard and annoying interference, use the recommended accessories only. FOR YOUR SAFETY DO NOT REMOVE THE OUTER COVER To prevent electric shock, do not remove the cover. No user serviceable parts inside. Refer servicing to qualified service personnel. As the colours of the wires in the mains lead of this appliance may not correspond with the coloured markings identifying the terminals in your plug, proceed as follows: The wire which is coloured BLUE must be connected to the terminal in the plug which is marked with the letter N or coloured BLACK. The wire which is coloured BROWN must be connected to the terminal in the plug which is marked with the letter L or coloured RED. Under no circumstances should either of these wires be connected to the earth terminal of the three pin plug, marked with the letter E or the Earth Symbol. 2.3.2. Caution for AC Mains Lead For your safety, please read the following text carefully. This appliance is supplied with a moulded three-pin mains plug for your safety and convenience. A 5-ampere fuse is fitted in this plug. Should the fuse need to be replaced please ensure that the replacement fuse has a rating of 5 amperes and it is approved by ASTA or BSI to BS1362 Check for the ASRA mark or the BSI mark on the body of the fuse. 2.3.2.2. Before Use Remove the Connector Cover as follows. If the plug contains a removable fuse cover you must ensure that it is refitted when the fuse is replaced. If you lose the fuse cover, the plug must not be used until a replacement cover is obtained. A replacement fuse cover can be purchased from your local Panasonic Dealer. If the fitted moulded plug is unsuitable for the socket outlet in your home then the fuse should be removed and the plug cut off and disposed of safety. There is a danger of severe electrical shock if the cut off plug is inserted into any 13-ampere socket. If a new plug is to be fitted please observe the wiring code as shown below. If in any doubt, please consult a qualified electrician. 2.3.2.3. How to Replace the Fuse 1. Remove the Fuse Cover with a screwdriver. 2. Replace the fuse and attach the Fuse cover. 6 2.4. 2.4.1.
