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.

• DISPLAY TYPE is TYPE D.

• Display of TUNER sources will be as follows : European Models : Upper Display=PS/frequency, Middle Display=clock, Lower Display=Status Other Models : Upper Displa y=SNPS, Middle Display =cloc k, Lower Display=Status

• CD/USB source display will be as follows : Upper Display=P-TIME, Middle Display=clock, Lower Display=Status

●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.

●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.

●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 : FMA

• Forced MIDDLE : FMM

• Forced WIDE : FMW

• Forced NARROW : FMN

●CD source test mode specifications

•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 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)

• 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 27 (5V 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.

TEST MODE

DPX701/701U/701UY DPX-MP7090U

• 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.

• Using the VOL knob and [ ] / [ ] key, the Fader can be adjusted in 3 steps : R15 ↔ 0 ↔ F15 (The initial value is 0)

• Using the VOL knob and [ ] / [ ] key, the Balance can be adjusted in 3 steps : L15 ↔ 0 ↔ R15 (The initial value is 0)

• Using the VOL knob and [ ] / [ ] key, the Bass / Middle / Treble Level can be adjusted in 3 steps : –8 ↔ 0 ↔ +8 (The initial value is 0)

• Using the VOL knob and [ Rear can be adjusted in 2 steps : Through ↔ 220Hz (The initial value is Through)

• Using the VOL knob and [ Woofer can be adjusted in 2 steps : 50Hz ↔ Through (The initial value is Through)

• Using the VOL knob and [ Phase can be adjusted in 2 steps : Re verse ↔ Normal (The initial value is Normal)

• Using the VOL knob and [ set can be adjusted in 2 steps : –8 ↔ 0 (The initial value is

• Using the VOL knob and [ ON/OFF can be adjusted in 2 steps : OFF ↔ ON (The initial value is OFF)

• Using the VOL knob and [ can be adjusted in 2 steps : OFF ↔ ON (The initial value is OFF)

• Bass f / Bass Q / Bass EXT / Middle f / Middle Q / Treble f do no appear in audio adjustments.

●MENU items

• Press [Q] key briefly to enter the MENU.

• The [DNPP/SBF] and [DIRECT] keys on the remote controller can also be used to enter the MENU.

• 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.)
