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.

•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.

● 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 : 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 tracks 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”, “AAC”)

•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)

6 8 1 0 : 0 1 2 3

Model name

Version

•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 25 (2V PRE).

DPX501/501U/501UY DPX-MP2090U

TEST MODE

● 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 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)

•Using the VOL knob and [] / [ ] key, the LPF Sub Woofer can be adjusted in 2 steps : 50Hz ↔ Through (The

initial value is Through)

•Using the VOL knob and [] / [ ] key, the Sub Woofer Phase can be adjusted in 2 steps : Reverse ↔ Normal (The

initial value is Normal)

•Using the VOL knob and [] / [ ] key, the Volume Offset can be adjusted in 2 steps : –8 ↔ 0 (The initial value is

0)

•Using the VOL knob and [] / [ ] key, the Loudness ON/OFF can be adjusted in 2 steps : OFF ↔ ON (The

initial value is OFF)

•Using the VOL knob and [] / [ ] key, 2-Zone ON/OFF 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.)

CLK

500msec 500msec 500msec

● Special display when all lights are on

When all lights are on with the STANDBY source, the following displays are made when the keys shown below are pressed.

[1] key Version is displayed (forwarding)

(Display) TYPE : x___ (“x" is displayed hexadecimally)

→529K–1.02 (“Development name” – “Version”)
