10、diagnosis functionThe oscillation diagnosis (existence of oscillation andmeasurement of period) of a sub-clock is performedbefore the test mode is entered. If the diagnosis result isOK, the system enters the test mode.If the diagnosis result is NG, the oscillation of the sub-clock is diagnosed again

11、. If the result is OK, the systementers the test mode. If the diagnosis result is continu-ously NG five times, the system stops with ERR 1 andERR 2 displayed.(2) All-lighting mode All the fluorescent display indicators and LED lamps lightwhen the power is turned on while pressing the BANDkey. After

12、that, the all-lighting mode is canceled when anymain units key is pressed. The normal display obtainedwhen the selector is set to TUNER then appears.(3) Others The AMP test mode is not terminated even if the selectoris set to positions other than TUNER. In the AMP test mode, the muting during mode s

13、electionis not controlled. However, the operation during thepower-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 keysbelow provide a special operation according to the posi-tion w

29、 serial test mode when a serial codeTEST 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) Cance

30、ling the serial test mode The serial test mode is canceled to return to the ordinarymode by inputting a TEST OFF code (C27 EH). Afterthe ordinary mode was returned, the serial mode isreturned to the state before the test mode is entered.The backup operation is not initialized. The serial test mode i

31、s also canceled when the AC poweris 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 guaranteedwhen they are performed in the serial test mode. An identical code is o
