RXD-402/452/502/552/572S/A41/A51
CIRCUIT DESCRIPTION
1. Initialization
1-1 Setting of initial conditions
While pressing the [ENTER] key, put the plug into an AC power outlet.
2. Destination list of TUNER
Destinat- Tuner ion type BAND K,P M,V,X,Y M M,V,X,Y M K1 K2 K3 E1 E3 E1 E T RDS E2 RDS FM AM FM AM FM MW SW FM AM FM MW SW FM AM FM MW LW Receiving frequency range 87.5MHz~108.0MHz 530kHz~1700kHz 87.5MHz~108.0MHz 530kHz~1610kHz 87.5MHz~108.0MHz 530kHz~1610kHz 5.9MHz~17.9MHz 87.5MHz~108.0MHz 531kHz~1602kHz 87.5MHz~108.0MHz 531kHz~1602kHz 5.9MHz~17.9MHz 87.5MHz~108.0MHz 531kHz~1602kHz 87.5MHz~108.0MHz 531kHz~1602kHz 153kHz~279kHz Channel space IF RF 25kHz 100kHz +10.7MHz
1-2 Initializing operation
� A microcomputer is initialized for start when the AC power is turned on when pressing the [ENTER] key. At that time, CD mechanism and CASSETTE mechanism are also initialized. � During the initial operation,the display shows INITIALIZE and after that it will be returned to STANDBY condition.

3. Test mode
3-1 Test mode of the receiver
3-1-1 Setting of the test mode While pressing the [INPUT] key or [BAND] key, put the plug into an AC power outlet. 3-1-2 Canceling of the test mode Unplug an AC power cord from an AC power outlet. 3-1-3 Condition in test mode � Power � � � � ON � EX.BASS � � � OFF � S.W � � � � � � � OFF � Selector mode or FL indication
KEY SELECTOR MODE FL INDICATION � All the fluorescent display indicators and LEDs light on. [BAND] + AC ON TUNER � STANDBY and TIMER LEDs blink up. � The all illminated state is cleared by pressing any main unit keys or remocon keys. � AUX TEST

*BACKED UP DATA
1-4 Mechanism initialization
1-4-1 CD mechanism � Disc unclamps(traverse down). � Rotary tray rotates(1/3 rotation). � If a mechanism error occurs, CD ERR is indicated on the display. 1-4-2 DECK mechanism � When initial condition becomes NG for the third time, decide the error. The error condition is displayed as X ERR on the display. 1-4-3 Error display � If both mechanism (CD/DECK) error occur, the display is indicated as follows. CD & X ERR
[INPUT] + AC ON
AUX
