If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the power cord is less than 460 kohms, the set is defective. Be sure to test for leakage current with the AC plug in both polarities, in addition, when the sets power is in each state (on,offandstandbymode),ifapplicable.CAUTION Please heed the following cautions and instructions during servicing and inspection. Heed the cautions!Cautions which are delicate in particular for servicing are labeled on the cabinets, the parts and the chassis, etc. Be sure to heed these cautions and the cautions described in the handling instructions. Cautions concerning electric shock!(1) AnACvoltageisimpressedonthisset,soifyoutouch internal metal parts when the set is energized, youmaygetanelectricshock.Avoidgettinganelectricshock,byusinganisolatingtransformerand wearing gloves when servicing while the set is energized,orbyunpluggingthepowercordwhenreplacing parts, for example.(2) Therearehighvoltagepartsinside.Handlewithextra care when the set is energized.

Make a safety check after servicing!Check that all screws, parts and wires removed or disconnected when servicing have been put back in their original positions, check that no serviced parts have deteriorate the area around. Then make an insulation check on the external metal connectors and between the blades of the power plug, and otherwise check that safetyisensured.(Insulationcheckprocedure)Unplug the power cord from the power outlet, disconnect the antenna, plugs, etc., and on the power.

And MAC Address seal replacement is required.See FIRMWARE UPDATE PROCEDURE.Initializing this unit (Initialization for the factory)This unit initialization should be performed when the com, peripheral parts of com, and WLAN MODULE are replaced.d1. Press the power operation button X to turn off the power, and remove the AC plug from the socket.2. While holding down buttons CURSOR d and INPUT simultaneously, insert the AC plug into the wall outlet toturn on the power. (Factory Reset)3. Press the power operation button to place this unit on standby.4. While holding down buttons CURSOR f and 8 simultaneously, press the power button to turn on the power.(Initialized)5. Wait for more than 90 seconds after Initialized is displayed and then turn the power off.(During this time, start and initialize the network devices.)NOTE: If step 5 fails, start over from step 1. All user settings will be lost and the factory setting will be recovered after the set is initialized. So make sure to note down your setting beforehand for restoring after the initialization.Power operation button(X)Fast-revers/Reverse-skip button (8)CURSORd1112DISASSEMBLY Remove each part in the order of the arrows below.
