9.  PROTECTION  FACTOR  (SD  DETECTION/
DC  DETECTION)  IDENTIFICATION  TEST  MODE
When an error is detected, the FL tube alternately displays 
“PROTECTOR h PUSH POWER”.
    
r
  Press the [
?/1
] button.
 
* Buttons other than the [
?/1
] button are invalid.
“STANDBY” blinks three times on the FL tube.
    r
The protection release state (POWER OFF) is established.
(No FL tube display) 
    r  Press the [
?/1
] button two times.
The power to the system turns on, and the normal operation is 
established. (Restore) 
During the protection state: 
1.  If the AC plug is connected or disconnected during the 
protection state, the protection state is released, and the 
normal operation is established. (The protection state is not 
maintained.) 
2.    The protection factor is displayed by pressing the  [FUNCTION], 
[
A
] and [
>
] buttons at the same time during the protection 
state
 
(during the “PROTECTOR h PUSH POWER” display).
 
k  When SD is detected: Repeats
   “SD 
DETECT 
h PROTECTOR”.
 
k  When DC is detected: Repeats 
   “DC 
DETECT 
h PROTECTOR”.
PL:  SD detection
 
When the “L” output from the SD (shutdown) port on the 
S-MASTER POWER Driver Shutdown and voltage descent 
(15V or less) of 30V power supply (PVDD) are detected.
 DC 
detection
 
When the “L” output from the power/speaker error detection 
circuit (DC detection port) is detected for two seconds 
continually, the power system other than that of the FL tube 
is turned off, and the protection state is established.

ELECTRICAL  ADJUSTMENTS
When the optical pick-up assy is replaced, perform the 
“EXECUTING IOP MEASUREMENT”.
EXECUTING IOP MEASUREMENT (See page 27)
[FM Tune Level Check]
Procedure:
1.  Turn the power on.
2.  Input the following signal from Signal Generator to FM 
antenna input directly.
*  Carrier Freq  : A = 87.5 MHz, B = 98 MHz, C = 108 MHz
 
Deviation     : 75 kHz
 
Modulation   : 1 kHz
 
ANT input    : 35 dBu (EMF)
Note: Please use 75 ohm “coaxial cable” to connect SG and the set. You 
cannot use video cable for checking.
 
  Please use SG whose output impedance is 75 ohm. 
3.  Set to FM tuner function and tune A, B and C signals.
4. Confi rm “TUNED” is lit on the display for A, B and C 
signals.
The mark of “TUNED” means “The selected station signal is 
received in good condition.”
