DESTINATION LIST OF TUNER 1-1 Destination List of Tuner 2. TEST MODE 2-1. Initializing The system is initialized when the power is turned on while pressing the POWER key. (1) Contents of operation All the functions are initialized. 2-2. AMP test mode using main units keys 2-2-1. Entering the AMP test mode Turn on the power while pressing the BAND key. 2-2-2. Canceling the AMP test mode By turning off the power, the system is initialized and the test mode is canceled. 2-2-3. Contents of AMP test mode (1) Automatic POWER ON The POWER ON state is entered whenever the power is turned on while pressing the BAND key. All functions are then initialized and activated in the all-lighting mode. Sub-clock oscillation diagnosis function The oscillation diagnosis (existence of oscillation and measurement of period) of a sub-clock is performed before the test mode is entered. If the diagnosis result is OK, the system enters the test mode. If the diagnosis result is NG, the oscillation of the sub- clock is diagnosed again. If the result is OK, the system enters the test mode. If the diagnosis result is continu- ously NG five times, the system stops with ERR 1 and ERR 2 displayed. (2) All-lighting mode All the fluorescent display indicators and LED lamps light when the power is turned on while pressing the BAND key. After that, the all-lighting mode is canceled when any main units key is pressed. The normal display obtained when the selector is set to TUNER then appears. (3) Others The AMP test mode is not terminated even if the selector is set to positions other than TUNER. In the AMP test mode, the muting during mode selection is not controlled. However, the operation during the power-on sequence is the same as the normal operation. The SP protection operation is also the same as the nor- mal operation. In the AMP test mode using main units keys, the keys below provide a special operation according to the posi- tion where the selector is set. The main units keys except described below and the rotary encoder provide the normal operation. (4) When selector is set to TUNER KeyOperation EX. BASS keyIncrements the P.CALL every time this key is pressed. N.B. key Decrement the P.CALL every time this key is pressed. ENTER keySelects the display cyclically in the order below every time this key is pressed. 1 Write data in the unused area of E2PROM, then read the written data. If the read data is the same as the written data, RAM OK is displayed in the fluorescent display indicator. If the former is different from the latter, RAM NG is displayed. 2 Set the TUNER ATT to OFF and display the S level in hexadecimal when the ENTER key is pressed. (ATT OFF * is displayed in the fluorescent display indicator.) 3 Set the TUNER ATT to ON and display the S level in hexadecimal when the ENTER key is pressed. (ATT ON * is displayed in the fluorescent display indicator.) * The special display using the ENTER key is continued until the next operation is carried out. (*: S LEVEL) When keys other than ENTER are pressed in items 1 to 3 above, the TUNER ATT is set to OFF and the normal display appears. The operation corresponding to the key that has been pressed is performed in this case.

Pre condition : The equlizer becomes the condition to be pushed the AUTO key before (include N.B. circuit). (6) SERIAL TEST CODE LIST Refer to Service manual (B51-5210-00) of R-SA7 on page 7. BAND key Every time this key is pressed, all the displays go off and the normal display is selected cyclically. 2-3. RDS test mode using main units keys 2-3-1. Entering the RDS test mode Turn on the power while pressing the N.B. key. 2-3-2. Canceling the RDS test mode By turning off the power, the system is initialized and the test mode is canceled. 2-3-3. Contents of RDS test mode The POWER ON state is entered whenever the power is turned on while pressing the N.B. key. All the functions are then initialized. In the RDS test mode using main units keys, the keys below provides a special operation according to the posi- tion where the selector is set. The main units keys except described below and the rotary encoder provide the normal operation. KeyOperation EX. BASS keyPerforms the same operation as for remote control key DISPLAY every time this key is pressed. MODE keyPerforms the same operation as for remote control key PTY every time this key is pressed. N.B. keyPerforms the same operation as for remote control key TA every time this key is pressed. ENTER keySelects the display cyclically in the order below every time this key is pressed. 1 Write data in the unused area of EEPROM, then read the written data. If the read data is the same as the written data, RAM OK is displayed in the fluorescent display indicator. If the former is different from the latter, RAM NG is displayed. 2 Set the TUNER ATT to OFF and display the S level in hexadecimal when the ENTER key is pressed. (ATT OFF * is displayed in the fluorescent display indicator.) 3 Set the TUNER ATT to ON and display the S level in hexadecimal when the ENTER key is pressed. (ATT ON * is displayed in the fluorescent display indicator.) * The special display using the ENTER key is continued until the next operation is carried out. (*: S LEVEL) When keys other than ENTER are pressed in items 1 to 3 above, the TUNER ATT is set to OFF and the normal display appears. The operation corresponding to the key that has been pressed is performed in this case. 2-4. SERIAL TEST MODE (1) Setting the serial test mode The unit is put into the serial test mode when a serial code TEST ON is input during the POWER-ON sequence. In the 16-bit serial test mode, serial code C27FH is input. In the serial test mode, all remote control keys and ordi- nary serial codes are disabled. Only the panel keys per- form the same operation as usually. (2) Canceling the serial test mode The serial test mode is canceled to return to the ordinary mode by inputting a TEST OFF code (C27 EH). After the ordinary mode was returned, the serial mode is returned to the state before the test mode is entered. The backup operation is not initialized. The serial test mode is also canceled when the AC power is turned OFF. (3) Cautions The serial test code is prescribed as a 16-bit code only. The operations below are inhibited in the serial test mode. The operations mentioned above cannot be guaranteed when they are performed in the serial test mode. An identical code is output when the serial test mode code is input. R-SE9/SE9T(K) 1P 98.4.25 14:46 yW 7 5 R-SE9/SE9T CIRCUIT DESCRIPTION FL DISPLAY (FIP9GM6R) RESET CE REMOCON LEVEL IN EX.
