HOW TO THE PANEL MECHANISM ASSEMBLY

1. Fixed the position of operation side (Fixed the horizontal position when the panel opened)

q The mounting hardware (281) of operation side is rota-

tion (A) into the stop position with close side.

w As figure (B) line is just above and the gear (230) at-

tached to pin.

2. The slider assembly insert to bottom chassis

q The bracket for display panel (284) is leave down, in-

sert to the chassis (702). (C)

Rotary to the stop position

w The slider assembly insert to the chassis (702) after

that shift (D) direction.

e The bracket for display panel (284) is raised (E) direc-

tion.

r Keep the raising conditions, the slider assembly is shift

(F) direction. (Note) Do not bend the knob of chassis detection switch when the slider assembly insert.

TEST MODE

KDC-M7024/MP822

● How to enter the test mode

While pressing and holding the Preset 1 and Preset 3 keys, reset the unit.

● How to exit from the test mode

While holding the Preset 6 key, reset the unit. (Note) The test mode cannot be terminated by reset the unit, ACC OFF, power OFF and Panel detached, momentary power down.

● Initial status in the test mode

• Sources : ALL OFF

• Display : All segments are lit.

• Volume : -10 dB (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.)

● 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 possib le .

● Forced switching of K3I

Each press of the Preset 6 key in Tuner mode should switch K3I from AUT O → F orced Wide → F orced 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

● Test mode specifications of the CD receiver

• F orced 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 ke y jumps to the f ollowing track numbers: No. 9 → No. 15 → No. 10 → No. 11 → No. 12 → No. 13 → No. 22 → No. 14 → No. 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.

● Audio-related specifications

• Pressing the ✽ k ey 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 220Hz) 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 ke y pass during the audio adjustment as follo wing steps.

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).

● 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 activ ated at this time.)

● 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 : System microcomputer

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. (The All OFF
