2、 di ricambio identici a quelli specificati. After servicing and before returning set to customer perform a leakage current measurement test from all exposed metal parts to earth ground to assure no shock hazard exist. The leakage current must not exceed 0.5mA. CLASS 1 LASER PRODUCT 3122 110 03420 GB

7、M SAFTY NOTICE Plug the AC line cord directly into a 120V AC outlet (do not use an isolation transformer for this check). Use an AC voltmeter, having 5000 per volt or more sensitivity. Connect a 1500 10W resistor,paralleled by a 0.15uF 150V AC capacitor between a knomn good earth ground (water pipe,

8、 conduit, etc.) and all exposed metal parts of cabinet (antennas, handle bracket, metal cabinet screwheads, metal overlays, control shafts, etc.). SAFTY PRECAUTIONS LEAKAGE CURRENT CHECK Measure the AC voltage across the 1500 resistor. The test must be conducted with the AC switch on and then repeat

9、ed with the AC switch off. The AC voltage indicated by the meter may not exceed 0.3V.A reading exceeding 0.3V indicates that a dangerous potential exists, the fault must be located and corrected. Repeat the above test with the DVD VIDEO PLAYER power plug reversed. NEVER RETURN A DVD VIDEO PLAYER TO

10、THE CUSTOMER WITHOUT TAKING NECESSARY CORRECTIVE ACTION. READING SHOULD NOT EXCEED 0.3V DVD VIDEO PLAYER AC OUTLET AC VOLTMETER Test all exposed metal.

11、uit, etc. The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated dangerous voltage within the products enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation poi

12、nt within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. 2.2 SAFETY INSTRUCTIONS Battery Handling Guideline Since the battery is packed in soft package, to ensure its

13、better performance, its very important to carefully handle the battery 2.2.1 Soft Aluminium foil The soft aluminum packing foil is very easily damaged by sharp edge parts such as Ni-tabs, pins and needles. Dont strike battery with any sharp edge parts Trim your nail or wear glove before taking batte

14、ry Clean worktable to make sure no any sharp particle 2.2.2 Sealed edge Sealing edge is very flimsy Dont bend or fold sealing edge 2.2.3 Folding edge The folding edge is form in battery process and passed all hermetic test. Dont open or deform folding edge 2.2.4 Tabs The battery tabs are not so stub

15、born especially for aluminum tab. Dont bend tab 2.2.5 Mechanical shock Dont Fall, hit, bend battery body 2.2.6 Short Short terminals of battery is strictly prohibited, it may damage battery. 3.0 INSTRUCTION FOR USE 4.0 MECHANICAL INSTRUCTION Disassembly Procedure 1. Remove 5pcs of screws on the side

16、 of bottom cabinet (include the one behind plastic stand). 2. Slip the TFT section, then you can open the bottom cabinet. Be careful of the FFC which connect with main board and TFT board. 2. Open the bottom cabinet, up-plug all the wire connecter from main board (include the FFC connect with TFT bo

17、ard and main board), The wire connecter are for: DVD loader, Battery board. Remove all the screws on the main board (3pcs), and then take the main board from bottom cabinet. 4.0 MECHANICAL INSTRUCTION 3. Up-plug the FFC from DVD driver, then you can take out the DVD Driver. 4. Remove the flex FFC on

18、 the bottom side behind the black flannel. 5. Remove 4pcs of screws on the battery board. Then take out the battery together with the battery board. Note: the battery was fixed by two side tape! Remove 6pcs of screws on the DVD top cabinet, you can separate the DVD top cabinet and TFT back cabinet.

19、4.0 MECHANICAL INSTRUCTION 6. Remove 8pcs of screws on the TFT back cabinet. Then you can open the display frame, carefully! ( There is a catch as shown in the pictures) 7. To remove the hinge, remove the screws on the hinge. 8. To remove the TFT, de-soldering the wire connected between panel and TF

20、T board first; After this, up-plug the FFC from TFT board which behind the black flannel; Then you can separate the panel. Be aware that the panel is fixed by 4pcs two side tape 4.0 MECHANICAL INSTRUCTION 9. up-plug the speaker line from TFT board, and dont forget de-soldering the black ground wire

21、behind black flannel. At last you can take out the driver board from cabinet using eradicator. 10.
