All functions arethen initialized and activated in the all-lighting mode.Sub-clock oscillation diagnosis functionThe oscillation diagnosis (existence of

10、 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. If the result is OK, the systementers the test mode. If

11、 the diagnosis result is continu-ously NG five times, the system stops with ERR 1 andERR 2 displayed.(2) All-lighting modeAll the fluorescent display indicators and LED lamps lightwhen the power is turned on while pressing the BANDkey. After that, the all-lighting mode is canceled when anymain units

In the AMP test mode, the muting during mode selectionis not controlled. However, the operation during t

13、hepower-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 where the selector is set. The main units keysexcept descri

SERIAL TEST MODE(1) Setting the serial test mode The unit is put into the serial test mode when a serial code“TEST ON“

29、 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 modeThe serial test mod

30、e 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 is also canceled when the AC poweris turned O

31、FF.(3) CautionsThe 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 output when the serial test mode codeis input.R-
