10.3.1. EEPROM Checksum (ROM Correction)
Purpose: To check for microprocessor firmware version and EEPROM checksum (ROM correction).
Below are the procedures for this mode.
Step 1: Enter into Doctor mode (for more information, refer to section 10.3 on key operations 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 of EEPROM (if applicable) will appear on FL display.
Below are the procedures for this mode.

· When entering into DOCTOR MODE, the firmware version and checksum 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.
the microprocessor shall be made after calculating checksum by summing up the content of data area from EEPROM.
2. In the case that the correction point existence data is 0, [NO] shall be displated.

3. In cases that the filename is different even though a EEPROM is set, or no correction file exists, [NG] shall be displayed (the
correction point existence data is set to 0 at this condition).
correction point existence data is set to 0 at this condition).
Note: Microprocessor firmware refers to version number for microprocessor IC. 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.
