How to exit from the test mode Reset the unit, ACC OFF, power OFF, and come off the front panel assy for the unit. 3. Initial status in the test mode Sources: All OFF. Display: All segments were l

42、it. Volume: -10 dB (displayed as 30) Loudness: OFF CRSC: OFF regardless of the presence of switching function. SYSTEM Q: Flat. Aux: ON Display color: white (variable color display model only) Beep sound: ON 4. Special display in Tuner mode When any of the following messages is displayed in Tuner mod

43、e, the Front-end (F/E) may be bad condition. TNE2P NG: The EEPROM is set to the default (unstable values) because the F/E was shipped without passing through the adjustment process, etc. TNCON NG: Communication with the F/E to micro- processor is not possible. 5. Forced switching of K3I Each press o

44、f the Preset 6 key in Tuner mode should switch K3I from AUTO Forced Wide Forced Middle Forced Narrow AUTO. The initial status is AUTO and the display shows these modes as follows. AUTO : FMA Forced Wide: FMW Forced Middle : FMM Forced Narrow : FMN 6. Test mode specifications of the CD receiver Force

45、d ejection is inhibited in the reset start operation. When the unit is reset while a CD is loaded in it, the CD is not recognized by resetting. Each press of the Track Up key jumps to the following track numbers: No. 9 No. 15 No. 10 No. 11 No. 12 No. 13 No. 22 No. 14 No. 9 (The cycle restarts from h

46、ere.) Each press of the Track Down key jumps to the previous track number to the track being played. When the number of total tracks of an MP3 disc is nine or less, unit playback from a track 1. When the media to CD-DA, unit playback from track No.28 by key operation of preset 1 key. 7. Audio-relate

47、d specifications A short press of the Q key initiates the audio adjustment mode. Pressing the key on the remote initiates the audio ad- justment mode. Continuous holding of a remote control key is inhibited. Bass, Middle and Treble are adjusted in 3 steps of -8 / 0 / +8 with the Track Up/down keys (

48、default is 0). Balance is adjusted in 3 steps of Left L15 / 0 / R15 Max with the Track Up/down keys (default is 0). Fader is adjusted in 3 steps of Rear15 / 0 / F15 Max with the Track Up/down keys (default is 0). HPF is adjusted in 2 steps of Through/170Hz (or 200Hz) with the Track Up/down keys (def

49、ault is through). LPF is adjusted in 2 steps of Through/120Hz with the Track Up/down keys (default is through). Bass f, Bass Q, Bass EXT, Middle f, Middle Q and Treble f are not dealt with by the audio adjustment. 8. Menu-related specifications A short press of the PLAY/PAUSE key initiates the Menu mode. Pressing the DNPP key on the remote initiates the Menu mode. Continuous holding of a remote control key is inhibited. Contrast is adjusted press of the Track up/down key in 3 steps of 0 / 5 / 10 (default is 5). 9. Backup
