18、 of repaired locations is properly performed.When you solder while repairing, please be sure that there are no cold solder and other debris.Soldering should be finished with the proper quantity. (Refer to the example)4 Make sure the screws are tightly fastened.Please be sure that all screws are fast

19、ened, and that there are no loose screws.5 Make sure each connectors are correctly inserted.Please be sure that all connectors are inserted, and that there are no imperfect insertion.6 Make sure the wiring cables are set to their original state.Please replace the wiring and cables to the original st

20、ate after repairs.In addition, be sure that there are no pinched wires, etc.7 Make sure screws and soldering scraps do not remain inside the product.Please check that neither solder debris nor screws remain inside the product.8 There should be no semi-broken wires, scratches, melting, etc. on the co

21、ating of the power cord.Damaged power cords may lead to fire accidents, so please be sure that there are no damages.If you find a damaged power cord, please exchange it with a suitable one.9 There should be no spark traces or similar marks on the power plug.When spark traces or similar marks are fou

22、nd on the power supply plug, please check the connection and advise on secure connections and suitable usage. Please exchange the power cord if necessary.0 Safe environment should be secured during servicing.When you perform repairs, please pay attention to static electricity, furniture, household a

23、rticles, etc. in order to prevent injuries. Please pay attention to your surroundings and repair safely. 2. AdjustmentsTo keep the original performance of the products, optimum adjustments and confirmation of characteristics within specification.Adjustments should be performed in accordance with the

24、 procedures/instructions described in this manual.4. CleaningFor parts that require cleaning, such as optical pickups, tape deck heads, lenses and mirrors used in projection monitors, proper cleaning should be performed to restore their performances.3. Lubricants, Glues, and Replacement partsUse gre

25、ase and adhesives that are equal to the specified substance. Make sure the proper amount is applied.5. Shipping mode and Shipping screwsTo protect products from damages or failures during transit, the shipping mode should be set or the shipping screws should be installed before shipment. Please be s
