TEST MODE

● How to enter the test mode

Press and hold the [1] and [3] keys and reset. (While “– – – –” is being displayed, power can be ON for 30 minutes.)

● How to clear the test mode

Reset, momentary power down, Acc OFF, Power OFF, detach the panel.

● Test mode default condition

• Source is STANDBY.

• Display lights are all turned on.

• The volume is at -10dB (The display is 30).

• LOUD is OFF.

• CRSC is off regardless of the availability of switching function.

• SYSTEM Q is NATURAL (=FLAT).

• BEEP should always function when the key is pressed.

• TUNER mode [4] key frequency shall be 98.3MHz.

● CD receiver test mode specification

• Display mode default setting shall be P-TIME.

• Jumps to the following tracks by pressing the [ No. 9 → No. 15 → No. 10 → No. 11 → No. 12 → No. 13 → No. 22 → No. 14 → No. 9 (recursive) Note that when playing an MP3 / WMA disc with 8 files or less, the disc is played from the 1st track in the normal order.

• Pressing the [ ] key goes back by 1 track from the track being played.

•When playing an MP3 / WMA disc, display the file format before starting to play each file. (“MP3”, “WMA”)

• While in CD source, press the [1] key to jump to No. 28.

• While in CD source, press the [2] key to jump to No. 14. ∗ When the media is VIDEO-CD, audio and display are

changed. (LL → RR → ST)

• While in CD source, press the [3] key to display the CD mechanism model name and the version. Press the [3] k ey again to go back to the normal screen. (Time code displa y)

● AUDIO adjust mode

• Press the [AUD] ke y and enter the audio adjustment mode .

• Press the remote control [∗] key and [AUD] key to go into the audio adjustment mode.

• Both AUDIO FUNCTION MODE and SETUP MODE adjustment items are included.

• By pressing [AUD] key and then [FM] key, switch the item to be adjusted in the following order. (Only in forward rotation) The default item shall be Fader, and then the item is forwarded in the following order: Balance → Bass Level → Middle Level → Treble Level (thereafter arbitrary).

• Continuous forwarding by remote control is prohibited.

• Fader is adjusted by the VOL knob and [ ] / [ ] keys in 3 steps: R15 ↔ 0 ↔ F15. (Default value: 0)

• Balance is adjusted by the V OL knob and [ ] / [ ] keys in 3 steps: L15 ↔ 0 ↔ R15. (Default value: 0)

• Bass/Middle/T reb le Lev el are adjusted by the VOL knob and [ ] / [ ] keys in 3 steps: -8 ↔ 0 ↔ +8. (Default value: 0)

•Volume Offset is adjusted by the VOL knob and [ ] / [ ] keys in 2 steps: -8 ↔ 0. (Default value: 0)

• Loudness ON/OFF is adjusted by the V OL knob and [ ] / [ ] keys in 2 steps: OFF ↔ ON. (Default value: OFF)

● MENU

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

• Press the remote control [DNPP/SBF] key or the [DIRECT] key to enter the MENU.

• Continuous forwarding by remote control is prohibited.

● Backup current measurement

If reset while in ACC OFF (Back Up ON) condition, MUTE terminal goes off 2 seconds later, rather than 15 seconds. (During this time, the CD mechanism does not function.)

● Fluorescent tube (ED1) short-checking

• When the source is ST ANDBY, press the [ATT] key to switch the process 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 back to the

step 1 and then repeats the steps.

● Initializing AUDIO-related setting value

Press the [ ] key in the STANDBY source and reset the AUDIO setting value to the test mode default value.

● Other

• When started in Test Mode, duration of prohibiting LINE MUTE shall be changed from 10 seconds to 1 second.

• When in Test Mode, when DC offset error detection is run, the detection information is not written into the E2PROM.

• 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 successfully completed : “CD_O” When finished but unsuccessful: “CD_X” ∗ CD mechanism information clearing is no good.

3. This mode is cancelled by resetting. (The last screen will not be retained.)

● Clearing DC offset error detection data

(E2PROM data clearing)

1. Press and hold [3] and [6] keys and reset-start to go into the DC offset error display mode. (While “– – – –“ is being display ed, pow er can be ON f or 30 minutes.)

2. While in ST ANDBY source, the current DC offset error condition is displayed. When detected : “DC_ERR_ _” When not detected: “DC_OK_ _ _”

3. While error condition is being displayed, press [AUTO] key to clear the detection data. (Clear E2PROM)

4. DC offset error display mode is cancelled by resetting. (The last screen will not be retained.)

● Clearing CD mechanism information and service

information (E2PROM data clearing)

1. While pressing the [Q] key and [ATT] key, reset-start to start CD mechanism and service information initialization. (While “– – – –“ is being display ed, pow er can be ON f or 30 minutes.) [CD mechanism information]

• Displays I2C communication condition

• Displays CD mechanism error log

• Displays CD loading error data.

● FM/AM channel space switching

While power is OFF, press and hold [1] and [5] keys, and press [SRC] key to power ON.

● IC10 (X34-) Stereo adjustment (VCO adjustment)

While in test mode and all lights are lit (STANDBY), press and hold [1] key and press [6] key for 3 seconds or longer. “VCO ADJ” will be displayed for a second. (Adjusted data will be written on E2PROM.)
