KDC-MPV7026/WV6027
1. How to enter the test mode
• While holding the Preset 1 and Preset 3 keys, reset the unit.
2. How to exit from the test mode
•Reset the unit, momentary power down, ACC OFF, power
OFF, and Panel detached.
•(Note) The test mode cannot terminated by Panel is fall
down.
3. 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.
•BEEP :When pressing any keys, the buzzer
generates a beep at any time.
•DISPLAY TYPE: TYPE A
4. RDS automatic measurement
•An addition to disposal of substitute for visual check PS
display as usual production lines.
•P-CON terminal is OFF by force, when received the PS
data and in case of corrobaration PS display is
“RDS_TEST”. (“_” is mean blank.)
•This disposal is test mode only.
•P-CON is switching the source or return with power on→off.
5. Special display inTuner mode
When any of the following messages is displayed in Tuner
mode, the front end may be abnormal.
• “TNE 2P 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.
6. Forced switching of K3I
•Each press of the Preset 6 key inTuner mode should switch
K3I from AUTO →ForcedWide →Forced Middle → Forced
Narrow → AUTO. The initial status is AUTO and the dis-
play shows these modes as follows.
•AUTO:FMA
•Forced Wide :FMW
•Forced Middle : FMM
•Forced Narrow: FMN
TEST MODE
7. CD ReceiverTest Mode Specification
•When resetting to start, forced ejection of CD is prohib-
ited.When a CD is in place, the CD is not recognized when
reset.
•When this key is pressed, the mechanism jumps to
the following track.
No9 →No15 →No10 →No11 →No12 →No13 →
No22 →No14 →No9 (Return to the first track.)
• When this key is pressed, the track goes down by one
from the currently played track.
•When a CD being played, by pressing [1] key intermittently,
the mechanism can be made to jump to Track No.28.
8. Audio-related specifications
•Ashort press of the Q key initiates the audio adjustment
mode.
•Pressing the ✽key on the remote initiates the audio
adjustment mode.
•Fader is selected to the initial item.
• Continuous holding of a remote control key is inhibited.
•Bass, Middle andTreble are adjusted in 3 steps of -8/0/+8
with the Track Up/Down keys.
•Balance is adjusted in 3 steps of L15/0/R15 with theTrack
Up/Down keys.
•Fader is adjusted in 3 steps of F15/0/R15 with the Track
Up/Down keys.
•Volume Offset is adjusted in 2 steps of -8/0 with theTrack
Up/Down keys.
9. Menu-related specifications
•Ashort press of the MENU key initiates the Menu mode.
Except, tape source is usually press and hold 1 second to
enter the menu mode and short press initiates turn over.
•Pressing the DNPP/SBF key on the remote initiates the
Menu mode.
• Continuous holding of a remote control key is inhibited.
•Contrast is adjusted in 3 steps of 0/5/10 (5x7dot), 0/4/7
(14seg) with the Track Up/Down keys.
10. Backup current measurement
•When the unit is reset while ACC is OFF (i.e. by turning
Back-Up ON), the MUTE terminal goes OFF in 2 seconds
in place of 15 second.
