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

30、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 modeEThe serial test mode is canceled to return to the ordinarymode by inputting a “TEST OFF“ code (C27 EH). Afterthe ord

31、inary mode was returned, the serial mode isreturned 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 poweris turned OFF.(3) CautionsEThe serial test code is prescribed as a 16-bit code only.EThe operations below a

32、re inhibited in the serial test mode. The operations mentioned above cannot be guaranteedwhen they are performed in the serial test mode.EAn identical code is output when the serial test modecode is input.(6) When selector is set to positions other than TUNERENTER key Every time this key is pressed,
