TEST MODE

KDC-MP832U

●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 v ents: resetting, momentary power down, Acc OFF, Power OFF and removal of the panel.

●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.

• The Multi-function Key System are source dependent systems. (TUNER → Preset, CD / USB / CD-CH → Scan, etc.)

• Display of TUNER sources will be as follows : European Models : Upper Display=PS/frequency, Middle Display=spectrum analyzer/clock, Lower Display=multifunction Other Models : Upper Displa y=SNPS, Middle Display =spectrum analyzer/clock, Lower Display=multi-function

• CD/USB source display will be as follows : All Models : Upper Displa y=P-TIME, Middle Displa y= spectrum analyzer/clock, Lower Display=multi-function

• 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 b y a ne w 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 f ollowing 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 25 (2V PRE), 27(4V PRE), 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
