2. BEGINNING AND CANCELLATION
(1) Starting up the function and the display
After starting up, main menu No.1 is selected.
A. How to start diagnostic program Using the front panel keys of the main unit Plug in the AC power cord. With the Power OFF, hold down the "PRESET/TUNING simultaneously (Step 1), then press the "STANDBY/ON" key (Step 2). Sub menu No. 1 of the diagnosis main menu No. 1 will start.
" and "A/B/C/D/E" keys

FRONT PANEL

"STANDBY/ON" key "A/B/C/D/E" key "PRESET/TUNING " key
Step2. Press the "STANDBY/ON" key.
Step1. Hold down the "PRESET/TUNING " and "A/B/C/D/E" key simultaneously.
B. Settings for start-up of diagnostic program The settings used when starting the diagnostic program are as follows.
1. EFFECT LEVEL CHANNEL LEVEL (dB) 2. MUTING 3. INPUT (VIDEO) 4. CENTER SPEAKER 5. REAR SPEAKER 6. MAIN SPEAKER 7. LFE/BASS OUT 0 : OFF : DVD/LD (DVD/LD) : LARGE : LARGE : LARGE : SWFR : CENTER R SUR 0 L SUR 0 SWFR 0
C. Start-up display The protection history information appears on the front panel display.
q FL display at start-up of diagnostic program When the diagnostic program has started, the check sum of the main microcomputer or the protection history (*1) is displayed. If the protection function has been activated in the past, the type and voltage value are displayed. After a few seconds the diagnosis function menu will appear. (*1) If a faulty condition is detected such as excessive current, a bad power supply or excessive amplifier DC offset, the Power will be switched OFF automatically. Note) For the voltages of the power and DC protection functions, see the diagnosis main menu No. 9, which will be described later. The protection history will be cleared when "RESERVED" is selected in the diagnosis main menu No. 8 and FACTORY PRESET is engaged. q Protection history The following examples show how the protection history is displayed:

CHK S UM : X X X X X

Appears when the protection function has not been activated. Displayed the check sum (4-digit, hexadecimal) and the version (one letter) of the main microcomputer.

I P RO T E C T I ON

Appears when the current protection function has been activated. When power is turned on in an abnormal condition, the power relay will come on, protection will operate immediately, and power will turn off. Appears when the power supply protection function has been activated. For the % value, the voltage at that point is shown by 5V/100%. When power is turned on in an abnormal condition, power will turn off after half a second.

P S P R T : X X%

D C P R T : X X%
Appears when the power amp DC protection function has been activated. For the % value, the voltage at that point is shown by 5V/100%. When power is turned on in an abnormal condition, power will turn off after two seconds.

(2) Exiting method

The diagnosis function can be exited by any of the following procedures. Take care with the setting of backup memory initialization menu (diagnosis No. 8) when releasing the diagnosis function. 1. Select sub-menu No. 4 "EXIT" of the diagnosis main menu No. 12. 2. Press the "STANDBY/ON" key on the main unit or "STANDBY" key on the remote control to turn Power OFF.
3. OPERATION AND DISPLAY WHEN STARTING DIAGNOSIS FUNCTION
(1) Selection of diagnostic menu
The diagnostic menu and the sub-menu can be selected by using the front panel keys of the main unit or the remote control unit. q Selection by using the front panel keys of the main unit The main menu can be changed cyclically by using the "PROGRAM / " keys, and the sub-menu, by using the "PRESET/TUNING / " keys. The " " key will increase the main or sub-menu number.

No.1 ANALOG THROUGH

The input is fixed to analog (A/D). There are two sub-menus.

1. MAIN BYPASS

1 MA I N B Y P A S S
The L/R signals bypass the digital circuit, and are output to the MAIN L/R. The L/R signals are output without being processed to the CENTER/SUBWOOFER and REAR L/R through the DSP. (Remote control code 7A-88: "1" key [DSP mode])

LARGE: Mode in which speakers with high bass-sound playback capability (large unit) are used. Full-range signals present on the channel are output from the speaker. SMALL : Mode in which speakers with low bass-sound playback capability (small unit) are used. Low bass signals (below 90Hz) on the channel are mixed into the channel selected by the LFE/BASS setting. NONE: Mode in which center speaker is not used. The center channel signal is reduced by 3 dB and mixed into MAIN L/R. LFE/B:MAIN : Mode in which subwoofer speaker is not used. The LFE channel signal is reduced by 4.5 dB and mixed into MAIN L/R. But because of the phase difference, the MAIN L/R output is not simply summed.

No.6 DISPLAY CHECK

Check program for FL display. The display status will change as follows with sub-menu operation. signal route is the same as "2. EFFECT OFF" of "No. 4 PRO LOGIC".

6 V FD CHCK

Initial display All segments turn off All segments turn on (See page 35) (lattice form) Alternate segments turn on
Software Release date display
A defect of the FL drive port and FL display segments can be detected by using "All segments turn off" and "All segments turn on". A short-circuit between adjacent segments can be detected by using "Alternate segments turn on" (lattice form).

9 SI :

Turning the "INPUT SELECTOR". SI: Tuner signal sensitivity level For return to the K1/K2 menu, press the "PRESET/TUNING "key.

9 DC :

Press the "PRESET/TUNING " key. DC: DC protection value (normal value: 1-13) For return to the SI menu, press the "PRESET/TUNING "key.

9 PS :

Press the "PRESET/TUNING " key. PS: Power voltage protection value (normal value: 23-38) For return to the DC menu, press the "PRESET/TUNING "key. For return to the initial display, press the "PRESET/TUNING "key again.
