R-SE7/SE-7(G)
CIRCUIT DESCRIPTION
[ AUTO key ] Selects the MUTE operation and equalizer cyclically in the order below for operation display every time this key is pressed.
-- -> MUTE operation -> Minimum -> Maximum -> �Pre-condition --
� In the operation for except the AUTO key, become precondition equlizer . � 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.
B 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 @ to B 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.
4-4. 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. E In the serial test mode, all remote control keys and ordinary serial codes are disabled. Only the panel keys perform the same operation as usually. (2) Canceling the serial test mode E 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. EThe serial test mode is also canceled when the AC power is turned OFF. (3) Cautions EThe serial test code is prescribed as a 16-bit code only. EThe 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. E An identical code is output when the serial test mode code is input.
4-3. RDS test mode using main unit's keys
4-3-1. Entering the RDS test mode ETurn on the power while pressing the TUNING UP key. 4-3-2. Canceling the RDS test mode E By turning off the power, the system is initialized and the test mode is canceled. 4-3-3. Contents of RDS test mode E The POWER ON state is entered whenever the power is turned on while pressing the TUNING UP key. All the functions are then initialized. E In the RDS test mode using main unit's keys, the keys below provides a special operation according to the position where the selector is set. The main unit's keys except described below and the rotary encoder provide the normal operation. Key Operation CLASS A key Performs the same operation as for remote control key "DISPLAY" every time this key is pressed. INPUT SEL. key Performs the same operation as for remote control key "PTY" every time this key is pressed. N.B. key Performs the same operation as for remote control key "TA" every time this key is pressed. ENTER key Selects the display cyclically in the order below every time this key is pressed. @ 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. A 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.)
