?/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

special menu mode is executed, perform this adjustment.

1.  Adjustment jig
The color pattern generator that can output 100% in NTSC/PAL/ 
HD color bar signal to the component and the composite at the 
same time is necessary for the adjustment.
When there is no color pattern generator, it is possible to substitute 
it by the Blu-ray Disc player that can output the component termi-
nal and the video terminal at the same time (Substitution model 
name example: BDP-S350).

Deviation 

: 75 kHz

Modulation 

: 1 kHz

ANT input 

: 35 dBu (EMF)

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