Be sure to test for leakage current with the AC plug in both polarities, in addition, in each power ON, OFF and STANDBY mode, if applicable.CAUTION Please heed the points listed below during servicing and inspection. Heed the cautions!Spots requiring particular attention when servicing, such as the cabinet, parts, chassis,etc., have cautions indicated on labels. be sure to heed these causions and the cautions indicated in the handling instructions. Caution concerning electric shock!(1) An AC voltage is impressed on this set, so touching internal metal parts when the set is energized could cause electric shock. Take care to avoid electric shock, by for example using an isolating transformer and gloves when servicing while the set is energized, unplugging the power cord when replacing parts, etc.(2) Tere are high voltage parts inside. Handle with extra care when the set is energized. Caution concerning disassembly and assembly!Through great care is taken when manufacturing parts from sheet metal, there may in some rare cases be burrs on the edges of parts which could cause injury if fingers are moved across them. Use gloves to protect your hands. Only use designated parts!The sets parts have specific safety properties (fire resistance, voltage resistance, etc.). For replacement parts, be sure to use parts which have the same poroperties. In particular, for the important safety parts that are marked z on wiring diagrams and parts lists, be sure to use the designated parts. Be sure to mount parts and arrange the wires as they were originally!For safety seasons, some parts use tape, tubes or other insulating materials, and some parts are mounted away from the surface of printed circuit boards. Care is also taken with the positions of the wores omsode amd clamps are used to keep wires away from heating and high voltage parts, so be sure to set everything back as it was originally. Inspect for safety after servicing!Check that all screws, parts and wires removed or disconnected for servicing have been put back in their original positions, inspect that no parts around the area that has been serviced have been negatively affected, conduct an inslation check on the external metal connectors and between the blades of the power plug, and otherwise check that safety is ensured.(Insulation check procedure)Unplug the power cord from the power outlet, disconnect the antenna, plugs, etc., and turn the power switch on. Using a 500V insulation resistance tester, check that the inplug and the externally exposed metal parts (antenna terminal, headphones terminal, input terminal, etc.) is 1M or greater. If it is less, the set must be inspected and repaired.Many of the electric and structural parts used in the set have special safety properties. In most cases these properties are difficult to distinguish by sight, and using replacement parts with higher ratings (rated power and withstand voltage) does not necessarily guarantee that safety performance will be poreserved. Parts with safety properties are indicated as shown below on the wiring diagrams and parts lists is this service manual. Be sure to replace them with parts with the designated part number.(1) Schematic diagrams .Indicated by the z mark.(2) Parts lists .Indicated by the z mark.Using parts other than the designated parts could result in electric shock, fires or other dangerous situations.CAUTION Concerning important safety partsRadioFans.CN 收音机爱 好者资料库3NOTE FOR SCHEMATIC DIAGRAMWARNING:Parts marked with this symbol z have critical characteristics. Use ONLY replacement parts recommended by the manufacturer.CAUTION:Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis resistance check. 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 unit is defective.WARNING:DO NOT return the unit to the customer until the problem is located and corrected.NOTICE:ALL RESISTANCE VALUES IN OHM. k=1,000 OHM / M=1,000,000 OHMALL CAPACITANCE VALUES IN MICRO FARAD.

Turn off the power using ON/STANDBY button.2. Press ON/STANDBY button while simultaneously pressing STANDARD and DSP SIMULATION buttons.3. Check that the entire display is flashing with an interval of about 1 second, and release your fingers from the 2 buttons and the microprocessor will be initialized.Service Jigs When you repair the printing board, you can use the following JIG (Extension cable kit). Please order to Denon Official Service Distributor in your region if necessary.8U-110084S : EXTENSION UNIT KIT : 1 Set(Refer to 21 page)Note: If step 3 does not work, start over from step 1. All user settings will be lost and this factory setting will be recovered when this initialization mode.
