4 1 Safety Precautions 1.1. General Guidelines 1. 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 essen- tial 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. 2. 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 acci- dents resulting in personal injury from electrical shocks. It will also protect AC Adaptor from being damaged by acci- dental shorting that may occur during servicing. 3. When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have been over- heated or damaged by the short circuit. 4. After servicing, see to it that all the protective devices such as insulation barriers, insulation papers shields are properly installed. 5. After servicing, make the following leakage current checks to prevent the customer from being exposed to shock hazards. 1.2. Leakage Current Cold Check 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. 1.3. Leakage Current Hot Check (See Figure. 1) 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.

5 1.4. How to Discharge the E.Capacitor on Flash P.C.B. CAUTION: • Be sure to discharge the E.Capacitor on Flash P.C.B. before disassembling. • Be careful of the high voltage circuit on Flash P.C.B. when servicing. [Discharging Procedure] 1. Remove the Top Case Unit. 2. Put the insulation tube on the lead part of resistor (ERG5SJ102: 1kΩ / 5W). (An equivalent type of resistor may be used.) 3. Put the resistor between both terminals of E.Capacitor on the Flash P.C.B. for approx. 5 seconds. 4. After discharging, confirm that the E.Capacitor voltage is lower than 10V by using a voltmeter.

6 2 Warning 2.1. Prevention of Electrostatic Discharge (ESD) to Electrostatically Sensitive (ES) Devices Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Elec- trostatically Sensitive (ES) Devices. The following techniques should be used to help reduce the incidence of component damage caused by electrostatic 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 compara- ble 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.

7 2.3. How to Replace the Lithium Battery 2.3.1. Replacement Procedure 1. Remove the TOP P.C.B.. (Refer to Disassembly Procedures.) 2. Unsolder the each soldering point of electric lead terminal for Lithium battery (Ref. No. “B7001” at component side of TOP P.C.B.) and remove the Lithium battery together with electric lead terminal. Then replace it into new one. NOTE: The Lithium battery includes electric lead terminals. NOTE: This Lithium battery is a critical component. It must never be subjected to excessive heat or discharge. It must therefore only be fitted in requirement designed specifically for its use. Replacement batteries must be of same type and manufacture. They must be fitted in the same manner and location as the original battery, with the correct polarity contacts observed. Do not attempt to re-charge the old battery or re-use it for any other purpose. It should be disposed of in waste products destined for burial rather than incineration. NOTE: Above caution is applicable for a battery pack which is for DMC-GX80/GX85/GX80K/GX85K/GX80W/GX85W/GX80C/GX85C/ GX80H series, as well.
