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. (While “----” is being displayed, 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, 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.

● 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 follo wing 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 receiver test mode specifications

• Display mode default setting shall be P-TIME

• Jumps to the next tracks by pressing the [ No. 9 → No. 15 → No. 10 → No. 11 → No. 12 → No. 13 → No. 22 → No. 14 → No. 9 (Recursive) It must be noted, however, that when paying MP3 / WMA /

• 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 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 (4V PRE).

● Audio adjust mode

Model with no DSP

• By pressing [AUD] key for less than 1 second, the audio adjustment mode can be entered.

• Using the remote controller [∗] key and [AUD] key, the audio adjustment mode can be entered.

• Adjustment items of 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

● Fluorescent tube (ED1) short-checking

During STANDBY sourcing, each time [ATT] key is shortpressed, the processing is switched in the following order.

1. All lights off.

2. Every 125msec, light the odd and even number of the grid with the largest numbers.

3. Light only odd number terminals.

4. Light only even number terminals.

5. All lights on.

∗ After the step 5 above , the process goes bac k to the step 1 and then repeats the steps.

● Other

• At Power ON, “CODE_OFF”, “CODE_ON” displays will not be made.

•When sourcing STANDBY, by pressing [AUT O] k e y f or less than 1 second, GREEN/RED of the key illumination is switched.

• When staring up in the test mode, LINE MUTE prohibition time is set to 1 second instead of 10 seconds.

• While in the test mode, even when a DC offset error is detected, the detection information will not be written to the E2PROM.

• While in the test mode, even after an elapse of pre-set time, the backup memory items will not be written to the E2PROM.

• Information Clear mode for Test Mode, backup/installer memory, and CD mechanism error log. In the DC offset error detection information clear mode, DEMO mode operation will not be conducted. Also, in the above mode , the menu of the STANDBY source will not display DEMO ON/OFF switching items.

• While in the test mode, and at the same time, PM_DET of the 60th terminal (System µ-com) is H, the following will apply to the EJECT key, regardless of whether a disc is in the unit or not. Panel full OPEN/CLOSE is conducted with a push for less than 1 second. (Protection time : 3 seconds) As far as this item is concerned, eject will be achieved by for at least 1 second push on the EJECT key.

● Clearing bac kup/installer memory and CD mecha-

nism information, and service information. Clearing E2PROM data.

1. While pressing and holding the [Q] key and the [ATT] key, reset-start to start backup/installer, memory data, and CD mechanism and service information initialization. (While “----” is being displayed, power can be ON for 30 minutes.) [CD mechanism information]

•Displays I2C communication condition

• Displays CD mechanism error log

• Displays CD loading error data.

• Displays CD ejection error data.

• Displays CD time code error count data (missing count).

•Displays CD time code error count data (count not updated).

[Service Information]

•Displays power ON time is displayed.

•Displays CD operation time.

• Displays number of CD EJECT times.

• Displays number of times panel was opened/closed.

• Displays forced Power OFF data.

2. After the initialization process is completed, the following is displayed. When the initialization is completed normally , the following is displayed. : “CD_O : AU_O_” When there was an error (or errors) and the initialization is not completed normally, the following is displayed. When backup/installer memory initialization is NG. : “CD_O : AU_X_” When CD mechanism information / service information initialization NG. : “CD_X : AU_O_” When all initialization NG. : “CD_X : AU_X_” Restore the NGs and initialize again.

3. While in this mode, even after an elapse of a pre-set time, no backup memory items will be written to the E2PROM.

4. This mode is released by resetting. (What was on the last screen will not be retained.)

● Clearing DC offset error detection information

(E2PROM (F/E) data clear)

1. While simultaneously pressing down on [3] and [6] keys, reset the unit to enter the DC offset error display mode. (While “----” is being displayed, power can be ON for 30 minutes.)

2. During ST ANDBY sourcing, the current DC offset error conditions will be displayed. When error detected : “DC_ERR” When error not detected : “DC_OK”
