To initialize the desired area, firstly select the desired item
from the EEPROM RESET menu. Change the selected
item from “CANCEL” to “OK”. Then press “ENTER”.

Memory” and “Factory”.
Execute this command only when the memory
(IC1007) on the B board is replaced.

“Common (3)” of the “COMMON DATA AREA”
shown in Table 1.
It initializes the data unique to the particular machine
and the shared data (various setup values of the user
menu”.
Because it initializes the serial number and accumula-
tive operation hours, do not execute this command.
