TEST MODE
●How to enter the test mode
Press and hold the [1] and [3] keys and reset.
(While “– – – –”is being displayed, power can be ON for 30
minutes.)
●How to clear the test mode
Reset, momentary power down, Acc OFF, Power OFF, de-
tach the panel.
●Test mode default condition
• Source is STANDBY.
• Display lights are all turned on.
• The volume is at -10dB (The display is 30).
• LOUD is OFF.
• CRSC is off regardless of the availability of switching func-
tion.
• SYSTEM Q is NATURAL (=FLAT).
• BEEP should always function when the key is pressed.
●Special display in tuner mode
Error is found in front-end, etc. if indications below are dis-
played while in tuner mode.
“TNE2P_NG” : Front-end E2PROM values are still default
(not determined).
“TNCON_NG” : Cannot communicate with the front-end.
●K3I forced switching
Every time when [6] key is pressed in tuner FM mode,
switched in the following order: AUTO →Forced WIDE →
Forced MIDDLE →Forced NARROW →AUTO. Default
status is AUTO, and displayed as shown below.
AUTO: FM1_98.1A
Forced WIDE: FM1_98.1W
Forced MIDDLE: FM1_98.1M
Forced NARROW: FM1_98.1N
●CD receiver test mode specification
• Display mode default setting shall be P-TIME.
• Jumps to the following tracks by pressing the [ ] key.
No. 9 →No. 15 →No. 10 →No. 11 →No. 12 →No. 13 →
No. 22 →No. 14 →No. 9 (recursive)
Note that when playing an MP3 / WMA / AAC disc with 8
files or less, the disc is played from the 1st track in the
normal order.
• Pressing the [ ] key goes back by 1 track from the track
being played.
• When playing an MP3 / WMA / AAC disc, display the file
format before starting to play each file. (“MP3”, “WMA”,
“AAC”)
• While in CD source, press the [1] key to jump to No. 28.
• While in CD source, press the [2] key to jump to No. 14.
• While in CD source, press the [3] key to display the CD
mechanism model name and the version. Press the [3] key
again to go back to the normal screen.(Time code display)
6680:0123
Model name Version
• When CD is the source, press the [6] key to jump to No.15.
At this time, the volume value is set to 27 (4V PRE).
●AUDIO adjust mode
• Press the [AUD] key and enter the audio adjustment mode.
• Press the remote control [∗] key and [AUD] key to go into
the audio adjustment mode.
• Both AUDIO FUNCTION MODE and SETUP MODE ad-
justment items are included.
•By pressing [AUD] key and then [FM] key, switch the item
to be adjusted in the following order. (Only in forward rota-
tion)
The default item shall be Fader, and then the item is for-
warded in the following order: Balance →Bass Level →
Middle Level →Treble Level →HPF Front →HPF Rear →
LPF Sub Woofer (thereafter arbitrary).
• Continuous forwarding by remote control is prohibited.
• Fader is adjusted by the VOL knob and [ ] / [ ] keys in
3 steps: R15 ↔0 ↔F15. (Default value: 0)

●Security
1) How to enter the forced POWER ON mode
While “– – – –” is being displayed, while simultaneously
pressing [Q] key and [4] key, press [RESET] button, With
this, it is possible to turn the power on for 30 minutes only.
2) How to clear the programmable security code
1. While “– – – –” is being displayed, press [ ] key for 3
seconds or longer while pressing the [AUTO] key. This
makes the “– – – –” display disappear.
2. Input “KCAR”, using the remote controller.
Press [5] key of the remote controller twice (Input for “K”)
and press [ ] key.
Press [2] key of the remote controller 3 times (Input for “C”)
and press [ ] key.
Press [2] key of the remote controller once (Input for “A”)
and press [ ] key.
Press [7] key of the remote controller twice (Input for “R”)
and press [ ] key.
3. The security is cleared and the unit enters STANDBY
source.
4. If wrong codes are input, “– – – –” will be displayed again.

●Clearing CD mechanism information and service
information (Clearing E2PROM data)
1. While pressing the [Q] key and [ATT] key, reset-start to start
CD mechanism and service information initialization.
(While “– – – –“ is being displayed, power can be ON for 30
minutes.)
[CD mechanism information]
• Displays I2C communication condition
• Displays CD mechanism error log
• Displays CD loading error data.
• Displays CD ejection error data
• Displays CD time code error count data (missing count)
• Displays CD time code error count data (count not updated)
[Service information]
• Displays power ON time is displayed
• Displays CD operation time
• Displays number of CD EJECT times
• Displays number of times panel was opened/closed
• Displays forced Power OFF data
2. After the initialization process is completed, the following is
displayed.
When successfully completed :“CD_O_ _ _”
When finished but unsuccessful:“CD_X_ _ _”
3. This mode is cancelled by resetting. (The last screen will
not be retained.)
TEST MODE
●Clearing DC offset error detection data
(E2PROM data clearing)
If DC voltage difference (DC offset error) is detected be-
tween audio power amplifier (power IC) ±outputs,
“DC_ERR_” is displayed on the display.When this occurs,
the audio is forced-mute and the display displays only
“DC_ERR_”.
Once this product detected a DC offset error, even if it is
restarted (or reset), its display displays “DC_ERR_”.
However, if the error is detected while inTest Mode, it is not
saved in E2PROM.
1. Press and hold [3] and [6] keys and reset-start to go into
the DC offset error display mode.
(While “– – – –“ is being displayed, power can be ON for 30
minutes.)
2. While in STANDBY source, the current DC offset error con-
dition is displayed.
When detected : “DC_ERR_ _”
When not detected: “DC_OK_ _ _”
3. While error condition is being displayed, press [AUTO] key
to clear the detection data. (Clear E2PROM)
4. DC offset error display mode is cancelled by resetting.(The
last screen will not be retained.)
●FM/AM channel space switching
While power is OFF, press and hold [1] and [5] keys, and
press [SRC] key to power ON.
