3.  Connect CD player to COAXIAL DVD IN jack (J2000 on the 

DIGITAL board), and play update CD.

 

Update is started when DSP detect update signal. The message 
“UPDATING” is displayed blinks every one second.

 

From this step, all user operation is prohibited. Power off is 
also prohibited.

4.  While main u-com is being updated, fl uorescent indicator tube 

is blacked out.

5.  When update data error is detected or disc is not matched with 

target model, error messages “DISC ERROR” and “PLAY 
DISC” are displayed to restart playing valid CD.

VERSION  CHECK
Function that displays the version number to check whether SPDIF 
update is necessary or not.
Procedure:
1.  While pressing  [MUTING] button, press the [

?/1

] button to 

turn on the main power.

2.  The message “VER X.XXX” is displayed. “X.XXX” is calcu-

lated by adding all fi rmware version.

 Example:
 

(MAIN ver. + DSP ver. + HDMI ver. + FARO ver. + 6)/10 = 
Displayed version

 

MAIN = 1.02, DSP = 1.01, HDMI = 1.00, FARO = 1.03

 

↓

 

(1.02 + 1.01 + 1.00 + 1.03 + 6)/10 = 1.006

 

1.006 = X.XXX

SPDIF  UPDATE  CHECK
Function that checks hardware error for SPDIF update.
This test takes about 15 seconds.
Procedure:
1.  While pressing  [DIMMER] and [2CH/A.DIRECT] buttons, 

press the [

?/1

] button to turn on the main power.

2.  The message “TESTING” is displayed and LED (MULTI 

CHANNEL DECODING indicator) is blinking.

3.  When abnormality is not found, the message disappears and 

LED is light up.

4.  Communication error between main microcomputer and DSP, 

the messages “UART” and “ERROR” are displayed and LED 
is blinking in fast speed.

  Communication error between HDMI microcomputer and 

DSP, the messages “HDMI” and “ERROR” are displayed and 
LED is blinking in fast speed.

 

Communication error between video processor and DSP, the 
messages “VIDEO” and “ERROR” are displayed and LED is 
blinking in fast speed.

 

Unknown error, the messages “UNKNOWN” and “ERROR” 
are displayed and LED is blinking in fast speed.

5.  To release from this mode, AC power cord pull out.

Procedure:
1.  Turn on the set.
2.  Input the following signal from signal generator to FM antenna 

input directly.

Carrier frequency : A = 87.5 MHz, B = 98 MHz, C = 108 MHz
Deviation 

: 75 kHz

Modulation 

: 1 kHz

ANT input 

: 35 dBu (EMF)

Note: Use 75 ohm coaxial cable to connect signal generator and the set. 

You cannot use video cable for checking.

 

  Use signal generator whose output impedance is 75 ohm.

3.  Set to FM tuner function and scan the input FM signal with 

automatic scanning.

4. Confi rm that input frequency of A, B and C are detected and 

automatic scanning stops.

When the station signal is received in good condition, automatic 
scanning stops.
