TEST MODE
How to enter the test mode
While pressing and holding the Preset 1 and Preset 3 keys, reset the unit.
Test mode specifications of the CD receiver
· Forced ejection is inhibited in the reset start operation. When the unit is reset while a CD is loaded in it, resetting does not recognize the CD. · Each press of the Track Up key jumps to the following track numbers : No. 9No. 15No. 10No. 11No. 12No. 13No. 22 No. 14No. 9 (The cycle restarts from here.) · Each press of the Track Down key jumps to the previous track number to the track being played. · When the number of total trucks of the MP3 disc or the WMA disc is less than 9, 1st truck is played. · When the disc media is CD, A short press of the Preset 1 key jumps to the track number 28. · When the model is equipped the CD mechanism assembly adapted for MP3 or MP3/WMA disc, the mechanism name and version number are displayed during the FL model is lower stand and Display mode of LCD model is DNPS.
How to exit from the test mode
While holding the Preset 6 key, reset the unit. Note : Turning ACC off, power off, momentary power down or panel detaching does not terminate the test mode.
Initial status in the test mode
· Sources : ALL OFF · Display : All segments are lit. · Volume : -10dB (displayed as "30") · Loudness : OFF · CRSC : OFF regardless of the presence of switching function. · SYSTEM Q : Flat · WOW : All OFF · BEEP : When pressing any keys, the buzzer generates a beep at any time. · AUX : ON · MENU SYSTEM Q : OFF · Variable model : Default is white · Multifunction : Source dependency (Preset, SCAN, etc.)
Audio-related specifications
· Pressing the key on the remote initiates the audio adjustment mode. · BL/F key on the Fader initials. · Continuous holding of a remote control key is inhibited, and workings are short press of any keys. · Bass, Middle and Treble are adjusted in 3 steps of -8 / 0 /+8 with the Track Up/Down keys (Default value at 0). · Balance is adjusted in 3 steps of L15 / 0 / R15 with the Track Up/Down keys (Default value at 0). · Fader is adjusted in 3 steps of R15 / 0 / F15 with the Track Up/Down keys (Default value at 0). · HPF is adjusted in 2 steps of OFF / 170Hz (or 200Hz) with the Track Up/Down keys (Default value at OFF). · LPF is adjusted in 2 steps of OFF / 120Hz with the Track Up/Down keys (Default value at OFF). · Bass f, Bass Q, Bass EXT, Middle f, Middle Q and Treble f are not dealt with by the audio adjust. · The WOW key passes during the audio adjustment as following steps (WOW model only).

Special display in Tuner mode
When any of the following messages is displayed in Tuner mode, the F/E may be abnormal. · "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 is not possible.
Forced switching of K3I
Each press of the Preset 6 key in Tuner mode should switch K3I from AUTOForced WideForced MiddleForced NarrowAUTO. The initial status is AUTO and the display shows these modes as follows. · AUTO : FMA · Forced Wide : FMW · Forced Middle : FMM · Forced Narrow : FMN

TEST MODE
Menu-related specifications
· A short press of the Q 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, and workings are short press of any keys. · Contrast is adjusted in 3 steps of 0 / 5 / 10 with the Track Up/Down keys (Default value at 5).
AM key Display panel E2PROM condition. (Display) PROM OK (Registered code) PROM NG (Code is write in error) PROM WAIT (Unregistered code) P-ROM NON (Panel security nonfunctional)
Panel mechanism
· Auto-panel close inhibition when set-in the CD. · The panel operation inhibition at power ON/OFF and ACC ON/OFF. · The panel position changing EjectLast with a short press of the PLAY/PAUSE keys.
Backup current measurement
When the unit is reset while ACC is OFF (i.e. by turning Backup ON), the MUTE terminal goes OFF in 2 seconds in place of 15 second. (The CD mechanism is not activated at this time.)
Other specifications Special display when the display is all on
Pressing the Preset keys while the power is ALL OFF displays the following information.
[PRESET 1] Version display (8 digits, Month/Day/Hour/Minute) (Display) SYS xxxxxxxx : PAN xxxxxxxx : FL model only MEM xxxxxxxx : 4 contrasts FL model only [PRESET 2] Serial number display (8 digits) (Display) SNo xxxxxxxx [PRESET 3] Short press : View power ON time.

CAUTION : For continued safety, replace safety critical components only with manufacturer's recommended parts (refer to parts list). Indicates safety critical components. To reduce the risk of electric shock, leakage-current or resistance measurements shall be carried out (exposed parts are acceptably insulated from the supply circuit) before the appliance is returned to the customer. · DC voltages are as measured with a high impedance voltmeter. Values may vary slightly due to variations between individual instruments or/and units.
