5.3 MODE 2 - Error History in EEPROM

(Press MD+ for Mode 2.)
The LED display in Mode 2 is the same as that in Mode 1, however,
the error history is stored in the EEPROM, so data is not lost when
the unit is powered OFF. To clear the contents of the EEPROM, push
S4 for three seconds or more, until the green LED starts flashing.
After the data is erased and initialization is finished, the green LED
stops flashing.
CAUTION: Do not clear the contents of the EEPROM until the error
messages are noted and written down for future reference.
In this mode, submode numbers can be used to select one of 16
records from 0 to F. Zero is the most recent error. Number one, is
the second most recent error, then 2,3,4,5,6,7,8,9, A,B,C,D,E, and F.

Error codes contain 4 bytes. All four bytes can be accessed using S1-
S4 buttons. The lower 2 digits show the error code in HEX. The third
digit shows the number of the byte (1-4) of the lower two digits. The
error codes should be noted and then interpreted using the charts in
Appendix D. One error includes 4 bytes of information and each byte
is shown by pressing S1 to S4. Access all four bytes to obtain a
detailed picture of an error. Byte 3 is a subset of Byte 2. See
Appendix D, Accessing and Interpreting Error Codes.
Refer to Figure 5-9, Mode 2, Error History in EEPROM. Also see Test
Mode Setting Buttons S1 to S4 on page 5-8.
S1=byte 3, S2=byte 2, S3=byte 1, S4=byte 0.
NOTE: The error history in Mode 2 is stored in the EEPROM. Data is
not lost when the unit is powered OFF.
