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 GBWarning !

7、OTICE 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, conduit,

8、 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 repeated with t

9、he 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 THE CUSTO

11、 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 point within

12、 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 better pe

13、rformance, 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 battery Clean

14、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 stubborn espe

15、cially 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 9pcs of screws on the side of botto

16、m cabinet. And dont forget the one behind bottom cabinet feet. 2. Open the bottom cabinet carefully. Firstly, unplug the wire connector of key board from the main board. (left bottom side); Then unplug the wire connector which connect the audio board and TFT board adhere by the flannel. 3. Unplug al

17、l the wire connecter from main board. The wire connecters are for DVD loader, battery board and TFT driver board, and speaker. Unplug the FFC from DVD driver, and then you can take out the DVD loader. 4.0 MECHANICAL INSTRUCTION Remove all the screws on the main board and audio board and unplug all t

18、he housing of them, then take the main board and audio board from bottom cabinet. 4. Remove the flex cable on the bottom side. 5. Remove all the screws on the battery board. Unplug the housing which connect the battery board and audio board; And then take out the battery with battery board. 6. Remov

19、e 6pcs screws from key board. 7. Remove 6pcs of screws on the display frame. Carefully open the display frame with the catches by screwdriver. (There are six catches as shown in the pictures) Then you can see next picture. 4.0 MECHANICAL INSTRUCTION 8. To remove the TFT, de-soldering the wire connec

20、ted between TFT and TFT board first. (Please note the wire location as shown in picture during re- assembly) And unplug wire connecter from TFT board and audio board. Take out the TFT board from cabinet using eradicator. Dont forget unplug the FFC of panel from the TFT board, it is behind the black

21、flannel. After this, take the panel from the front cabinet carefully. There are three two side tape rubbers as shown in the pictures 9. To remove the hinge, remove the screws on the hinge. 5.0 TROUBLESHOOTING SYMPTOM: BATTERY NO POWER Start Check Battery capacity? BATTERY CANT Power ON Check chargin
