Below are the procedures for this mode.
Step 1: Enter into Doctor mode (for more information, refer to section 9.2 on the key operation to enter into this mode.
Step 2: Check for firmware version and EEPROM checksum (By pressing STOP button on main unit followed by “4” and “7” on
remote control).
·
When entering into DOCTOR MODE, the firmware version and checksum data of EEPROM (if applicable) will appear on FL
display. Below is the information on the EEPROM IC (ROM correction) under 3 possible situations:
1. In the case that the correction point existence data is other than 0 (ie. correction file exists), EEPROM checksum display for
the microprocessor shall be made after calculating checksum by summing up the content of data area from EEPROM IC.
2. In the case when no EEPROM IC is installed. It is display as below (no display of checksum data)
3. In cases that the filename is different even though a EEPROM is installed, or no correction file exists, [NG] shall be displayed
(the correction point existence data is set to 0 at this condition).
Note:
Microprocessor firmware refers to version number for microprocessor IC located on PANEL P.C.B.. It is subject to change
which would be updated accordingly. ROM correction checksum refers to the HEX code that is displayed upon key buttons pressed
if an EEPROM is loaded in the unit.
9.3. Reliability Test Mode (CRS1 Mechanism)
Below is the process flow chart of ageing for the CD changer unit. (CRS1)
