TEST MODE
●How to enter the test mode
In order to enter the test mode, reset the unit while simultaneously pressing down [1] and [3] keys.
(Even when the security is set, power can be ON for 30 minutes.)
●How to clear the test mode
The test mode is cleared in case of any of the following e vents:
resetting, momentary power down, Acc OFF and Pow er OFF.
●Initial conditions of the test mode
• Source is STANDBY.
• Displays lights are all turned on.
• The volume is at –10dB (The display is 30).
• Loudness (LOUD) is OFF.
• CRSC is OFF, regardless of whether there are switching
functions or not.
• SYSTEM Q is NATURAL (=FLAT).
• BEEP will sound anytime with a less than 1 second push.
• Auxiliary (AUX) is ON.
• SWPRE is Sub woofer (2 PREOUT model)
●RDS/RBDS automatic measurement
Conventionally, the PS display has been visually checked on
the production line. This will be replaced by a new processing.
The PS data will be received and the PS contents is to be
verified as “RDS_TEST”. When this is verified, the P-CON
terminal is forced to go OFF. (In this case, “ _ ” means blank.)
→ This will be a dedicated test mode processing.
On the P-CON, when power is turned off once and, then,
turned on again, (Power OFF → ON) the unit will be restarted.
●Forced switching of K3I
In TUNER FM mode, each time [6] key is pressed, the functions move in the following cycle :
AUTO → forced WIDE → forced MIDDLE → force NARROW
→ AUTO
The initial condition is AUTO and the displays below will appear.
• AUTO : FM1_98.1A
• Forced MIDDLE : FM1_98.1M
• Forced WIDE : FM1_98.1W
• Forced NARROW : FM1_98.1N
●CD source test mode specifications
• Display mode default setting shall be P-TIME.
•Jumps are made 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 (Returns to the beginning)
It must be noted, however, that when paying MP3 / WMA /
AAC disk, which contain 8 files or less, the first track and
the following trac ks are played in order.
• When [ ] key is pressed, it goes down by 1 track.
• When playing an MP3/WMA/AAC disc, display the file format before starting to play each file. (“MP3”, “WMA”, “AA C”)
• When a CD is used as a source, by pressing [1] key f or less
than 1 second, a jump to the Track No. 28 is made.
• When a CD is used as a source, by pressing [2] key f or less
than 1 second, a jump to the Track No. 14 is made.
• When a CD is used as a source, by pressing [3] key f or less
than 1 second, a display of CD mechanism model name
and its version is made. When the pressing of [3] key for
less than 1 second is made for the second time, the normal
display is resumed. (Time code display)
●Special display when set to TUNER
When in TUNER mode, if any of the following displays appear,
there is an abnormality with the front end.
• “TNE2P_NG” : Front-end E2PROM values are still default
(not determined).
•“TNCON_NG” : In this condition, the communication with
the front-end is not possible.

Model name Version
• When a CD is used as a source, by pressing [6] key f or less
than 1 second, a jump to the Track No. 15 is made. At the
same time, the volume value is set to 25 (2V PRE).

●Test mode specification for USB source
• While in USB source, by [6] key, set the volume value to 15.
●Audio adjust mode
•By pressing [AUD] key for less than 1 second, the Audio
Adjust mode is entered.
• As with the [AUD] key, [∗] key on the remote controller can
be used to enter the Audio Adjust mode.
• As for the adjustment items, items for both the AUDIO
FUNCTION MODE and SETUP MODE are included.
• By pressing [AUD] or [FM] key briefly, switch the item to be
adjusted in the following order. (only in forward rotation)
The initial item will be Fader, which is followed by : Balance
→ Bass Lev el → Middle Level → Treb le Le v el → HPF Front
→ HPF Rear → LPF Sub Woofer (After this, it will be arbi-
trary)

• With the remote controller, continuous forwarding is prohibited.
• When a CD/USB is used as a source, the default item will
be the F/W Version.
●2-ZONE (Dual Zone) items
• When using sources other than the STANDBY source, using a short-press on [AUTO] or [TI] key, 2-ZONE ON/OFF
is achieved.
●Backup current measurement
When reset in Acc OFF (Back Up ON) condition, MUTE terminal goes off after 2 seconds, instead of 15 seconds. (During
this time, the CD mechanism does not function.)
●OPEL communication items (OPEL communica-
tion specification supporting model)
During the test mode, OPEL communication line outputs the
following (At every 500msec, the output condition of the communication line will be switched.)
