17、to interferences such as radio/TV interference and foreign noise.3 Make sure the soldering 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 e

18、xample)4 Make sure the screws are tightly fastened.Please be sure that all screws are fastened, 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 cabl

19、es are set to their original state.Please replace the wiring and cables to the original state 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 ins

20、ide the product.8 There should be no semi-broken wires, scratches, melting, etc. on the coating 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

21、spark traces or similar marks on the power plug.When spark traces or similar marks are found 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.Wh

22、en you perform repairs, please pay attention to static electricity, furniture, household articles, etc. in order to prevent injuries.
