Are the connections correct?2. Is the set being operated as described in the owner’s manual?3. Are the other components operating properly?If this unit does not operate properly, check the items listed in the table below. If the problem persists,there may be a malfunction.In this case, disconnect the power immediately and contact your retail outlet.GGeneralHSymptom Cause Countermeasure PageSet does notoperate properly.• External noise or interference iscausing the set to malfunction.• Reset the microprocessor. 26Display not litand sound notproduced whenpower switchedto on.• Power cord not plugged insecurely.• Check the connections onthe set's rear panel and theconnection of the power plug tothe power outlet.10Display lit butsound notproduced.• Wrong input source selected.• Volume control set to minimum.• MUTING is on.• Select the appropriate inputsource.• Turn volume up to suitable level.• Switch off MUTING.111112Display is off. • The Dimmer setting is set to“OFF”.• Set to something other than“OFF”.12Power turns offsuddenly andpower indicatorfl ashes red.(Flashes at 0.5second intervals)• Protection circuit activated dueto a rise in internal temperature.• Core wires of two speakersare touching each other or acore wire is sticking out ofthe terminal and touching theset’s rear panel, activating theprotection circuit.• Turn off the power, wait for theset to fully cool down, then turnthe power back on.• Place the set in a well-ventilatedlocation.• First unplug the power cord,then twist the core wires tightlyor terminate the speaker cables,then reconnect.8III8Power turns offsuddenly andpower indicatorfl ashes red.(Flashes at 0.25second intervals)• Set is damaged. • Turn off the power and contacta DENON service center.–TroubleshootingExplanation termsAAAC (Advanced Audio Coding)This is an internationally standardized audio datacompression scheme. It has a compression ratio1.4 times higher than the “MP3 audio compressionscheme adopted for “MPEG-1.BBit rateThis expresses the read amount per 1 second ofvideo/audio data recorded in a disc.DDynamic rangeThe difference between the maximum undistortedsound level and the minimum sound level that isdiscernible above the noise emitted by the device.FFinalizeThis is processing that enables playing back of discof CD, which was recorded using a recorder, byother players.MMP3 (MPEG Audio Layer-3)This is an internationally standardized audio datacompression scheme, using the “MPEG-1” videocompression standard. It compresses the datavolume to about one eleventh its original size whilemaintaining sound quality equivalent to a music CD.MPEG (Moving Picture Experts Group), MPEG-2,MPEG-4These are the names for digital compression formatstandards used for the encoding of video and audio.Video standards include “MPEG-1 Video”, “MPEG-2 Video”, “MPEG-4 Visual”, “MPEG-4 AVC”. Audiostandards include “MPEG-1 Audio”, “MPEG-2Audio”, “MPEG-4 AAC”.PProtection circuitThis is a function to prevent damage to componentswithin the power supply when an abnormalitysuch as an overload, excess voltage occurs ortemperature for any reason.In this unit, the power indicator blinks and the unitenters standby mode when an abnormality occurs.SSampling frequencySampling involves taking a reading of a sound wave(analog signal) at regular intervals and expressingthe height of the wave at each reading in digitizedformat (producing a digital signal).The number of readings taken in one second iscalled the “sampling frequency”. The larger thevalue, the closer the reproduced sound is to theoriginal.Speaker impedanceThis is an AC resistance value, indicated in Ω(ohms). Greater power can be obtained with thisvalue smaller.WWMA (Windows Media Audio)This is audio compression technology developed byMicrosoft Corporation.WMA data can be encoded using Windows Media®Player Ver.7, 7.1, Windows Media®Playerfor Windows® XP and Windows Media® Player 9Series.To encode WMA files, only use applicationsauthorized by Microsoft Corporation. If you usean unauthorized application, the file may not workproperly.
