(1) The user program stored in the EEPROM is transferred to the RAM
when power is turned on. Therefore, if the program is modified, it is
necessary to issue the EEPROM Write command from the programming
tool. Otherwise, the modified program is over-written by original
EEPROM contents at the next initial load timing.
(2) The data of RAM and calendar IC are backed up by built-in capacitor
and optional battery.
(3) When the optional battery is used, replace the battery periodically with
referring to the table below.
