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 events: resetting, momentary power down, Acc OFF and Power 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 Display=SNPS, Middle Display =clock, 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 tracks 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 for 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 for 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 for 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 for 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.

16

DPX701/701U/701UY DPX-MP7090U

TEST MODE

•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 Level → Middle Level → Treble Level → HPF Front

→HPF Rear → LPF Sub Woofer (After this, it will be arbitrary)

•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 [] / [ ] key, the HPF Front / Rear can be adjusted in 2 steps : Through ↔ 220Hz (The

initial value is Through)
