E 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

26、below and the rotary encoder provide the normal operation. KeyOperation CLASS A keyPerforms the same operation as for remote control key DISPLAY every time this key is pressed.

30、e 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 s

31、equence. In the 16-bit serial test mode, serial code C27FH is input. EIn 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 EThe serial test mode is canceled to return

32、 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 E

33、The 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. (6) When

34、selector is set to positions other than TUNER ENTER key Every time this key is pressed, master VOL- UME level is selected cyclically.
