The error message displayed as the Last Error Message (1) Communication error between SA-CD Module and Microprocessor When having had the communication error with the SA-CD Module more than a regulated number of time

9、s, the unit will reset the SA-CD Module after displaying the following message. This will continue to be displayed until the unit has recovered from the communication error. When the unit is ready to play back CDs and SA-CDs, the SA-CD Module and the Microprocessor communicate regularly. Check the s

10、ignal in reference to the communication between the SA-CD Module and the Microprocessor on Communication Waveforms page. The MOD_SCL is the clock that is transmitted from the SA-CD regularly. If this signal cannot be detected, the SA-CD Module may be broken. If so, replace the SA-CD Module. When the

11、 SA-CD Module has been replaced, ensure that the Playtime will be cleared. (2) Communication Error between D/A Converter and Front Microprocessor If no response is detected in the communication between the D/A Converter and the Microprocessor, the display will show the following message. Make the CD

12、/SA-CD or the USB replayable. Ensure that IIC communications have been established between R217 and R218 when the unit is switched from STOP to PLAY. If the error cannot be corrected through normal operations, U204 may be broken. If such is the case, replace U204. 2. Error messages that are not disp

13、layed in the Last Error Message (1) Error messages that can be displayed on the FL (Communication Error between the Front Microprocessor and EEPROM) If no response is detected between the Front Microprocessor and EEPROM within a regulated timeframe, the display will show the following message. Ensur

14、e that IIC communications have been established between R123 and R125 when the unit is powered on or put into STANDBY. IF the error cannot be corrected through normal operations, U101 may be broke. If such is the case, replace U101. When no disc information is displayed 120 seconds after the disc is

15、 loaded, the display will show the following message. Reset the SA-CD Module. If no information can be obtained after this operation has been repeated three times, the unit will open the tray by itself. The unit cannot play back the disc if this message appears.

17、 C a n_ P l a y _ 24 C Error Messages special to USB 1. Error Message displayed as the Last Error Message If no response is made in the communication between the USB Module U501 and the microprocessor within a designated timeframe, the display will show the following message. Refer to the Communicat

18、ion between USB Module and the microprocessor on the Communication Waveform page and check the signal. If the error message bellow cannot be cleared despite the unit performing normal operations properly, U501 may be broken. If such is the case, replace U501. If no response is made in the communicat

19、ion with an iPod-authenticated IC within a regulated timeframe, the display will show the following message. As the communication with the authenticated IC has not been established normally, ensure that the IIC signal is communicating at a normal level when the unit is connected with an iPod. The fr

20、equency of the IIC clock (IIC_SCL) is approximately 40 kHz only when the unit communicates with an iPod- authenticated IC. If no communication can be detected, check the soldering points of the microprocessor (U102), resistors (R155, R157) and the authenticated IC (U151). If the problem specifi c to

21、 the iPod cannot be rectifi ed, the authenticated IC (U151) may be broken. If that is the case, replace U151. When the iPod-authenticated IC has received error information, the display will show the following message. This message means that the authenticated IC is communicating properly. Try connec

22、ting another iPod. If no problem arises with another iPod, advise the user to repair the iPod. If the same problem arises with another iPod, the authenticated IC (U151) may be broken. If that is the case, replace U151. When a problem arises with the processing of the iPod authentication and signatur

23、e, the display will show the following message. If the following message appears instead of the above messages - iPodErrorIC”, iPodICErrorx and USB_Com_ Error_, try connecting another iPod. If no problem arises, advise the user to repair the iPod. If the error message persists, the authenticated IC

24、(U151) may be broken. If that is the case, replace U151.

26、ng with the USB Module, the display will show the following message. If the indication will not be changed to USB_Com_Err, the communication may be unstable. Refer to the communication between the USB module and the microprocessor on the communication waveform page and check the signal. If the messa

27、ge below cannot be cleared while the unit is functioning normally, U501 may be broken. If that is the case, replace U501. When the unit is connected with an incompatible UBS device or a device confi gured with an incompatible communication protocol or command, the display will show the following mes

28、sage. If this message is displayed, the device is incompatible and cannot be connected to the unit. If the information obtained from the USB has a fl aw or improper data, which are detected by the USB host controller in the unit, the display will show the following message. When the message appears,

29、 the device may be connected and used, but success is not guaranteed. If the signal comes in an incompatible format, the display will show the following message. The compatible formats are FAT16 and FAT32. In FAT32 the USB memory must be 128MB or bigger in size. This message means that the device is

30、 formatted in an incompatible cluster size. Normally, when USB memories are formatted on Microsoft Windows, FAT32 is the default, and if the memory size is up to 128MB, it will be formatted in a cluster size of 2KB, which is incompatible with the unit. Therefore, the memory size is recommended to be

31、 256MB or bigger. If the memory size is 128MB, format it with FAT16 (indicated as FAT on Microsoft Windows) instead of FAT32, and it will be compatible with the unit.

If the messa

34、ge below appears, the USB device cannot be operated through the units USB Bus power alone. An auxiliary power unit might enable the device to be used, but damage resulting from this would not be covered by the warranty. If the command will not be set within a set timeframe after PLAY, PAUSE, STOP, F

35、F, FR and such operations are carried out, the display will show the following message. This message will be displayed for 3 seconds and then the USB module will be reset. If the error indication persists after these operations, U501 may be broken as the unit will not accept a specifi c command alon

36、e. If no other error message will appear, replace U501. If the fi le has an incompatible extension or is 24KB or smaller in size, the display will show the following message. Extensions other than those mentioned in the instructions manual will be excluded from the warranty. Refer to the instruction

37、s manual and ensure that the extension and format is compatible with the unit. If the unit detects an incompatible sampling frequency or number of channels or an incompatible format fi le, the display will show the following message. Sampling frequencies, numbers of channels and formats other than t

38、hose mentioned in the instructions manual will be excluded from the warranty. Refer to the instructions manual and ensure that the format is incompatible. If the unit detects a DRM protected fi le, the display will show the following message. The unit is not made to and hence cannot play back DRM pr
