7 Self-Diagnostic Display Function
TOP PREVIOUS NEXT This unit is equipped with a self diagnostic display function which, if a problem occurs, it will display an error code corresponding to the problem. Use this function when performing maintenance on the unit. 7.1 How to enter the Self-Diagnostic Display Function mode. 7.2 Interpretation of Error Codes. 7.2.1 Abnormality Detection for CD Block 7.2.2 Detailed specification for F75 7.2.3 Abnormality Detection for Power Supply @ TOP PREVIOUS NEXT

7.1 How to enter the Self-Diagnostic Display Function mode.
TOP PREVIOUS NEXT 1. Turn the power on. 2. Set the operation selector to CD. (with no CD loading condition) 3. Press and hold the CD_STOP button for more than 2 seconds. While pressing the CD_STOP button, press and hold the F_SKIP button for 2 seconds."T" will appear on the FL display. (The set is in the Self-Diagnostic Function Mode) 4. Press CD OPEN tray. 5. Under self-diagnosis mode, press CD STOP key to display memorised abnormality. Every time the key is pressed, the memorised numbers of abnormality shall appear cyclically. Self-diagnosis mode will start even if CD_STOP key is released after F_SKIP key is pressed, as both keys use the same AD line. Retain the memory of abnormality as long as memories of the micro-p are backed up. When RAM check at the reset of micro-p fails, clear all the RAM.

RESET SW ON is not detected within the specified time under normal operation (including self-dianosis mode MDATA does not become H within 1 sec after MDATA is temporaly changed to input. Level detection is conducted when the selector is switched to CD under normal operation (including self-diagnosis mode).

F26

SENSE=L is not detected within a fail-safe period (20mSec) after the selector is switched to CD. SENSE=H is detected and system command is transmitted to CD LSI, under normal operation(including self-diagnosismode). CD tray is left open due to fail-safe function under normal operation.

7.2.2 Detailed specification for F75
TOP PREVIOUS NEXT For this model, a command needs to be transmitted quickly when CD LSI's RESET becomes H. Therefore, temporarily set the MDATA port as input and use it to detect CD power. 1. When the selector is switched to CD or power becomes on at CD mode, temporarily set MDATA port as input and check id MDATA is H. The check will start 20 mSec after the selector chane signal has been output. (CD RESET shall remain as L) 2. If the MDATA is not detected as H within 1 Sec after starting the check, memorise F75 and change CD_L to H. Maintain CD RESET as L prohibits command output to CD LSI. However, other operations such as accepting keys shall be continued. When theCD mode is re-selected, set CD_L to L as usual and cinduct CD power detection. Once the power is detected, resume the normal operation. (F75 shall not be cleared) 3.Once MDATA is detected as H. Change it to output and RESET. 4. Even during the normal operation at CD mode, set MDATA to input and detect the power as described in b. above when MDATA port is not used for output. The Circuit has to be designed to enable MDATA line detect H when it is set to input (especially pull-up and pull down),; @ TOP PREVIOUS NEXT

Accordingly, there may arise some error in voltage values and waveformsdepending upon the internal impedance of the tester or the measuring unit. No mark : Playback (( )) : CD <> : FM () : AM [] : AUX Importance safety notice : Components identified by mark have special characteristics important for safety. Furthermore, special parts which have purposes of fire-retardant (resistors), high-quality sound (capacitors), low-

noise (resistors), etc. are used. When replacing any of components, be sure to use only manufacturer´s specified parts shown in the parts list.

Caution !
IC, LSI and VLSI are sensitive to static electricity. Secondary trouble can be prevented by taking care during repair. Cover the parts boxes made of plastics with aluminium foil. Put a conductive mat on the work table. Ground the soldering iron. Do not touch the pins of IC, LSI or VLSI with fingers directly.
