NOTE

(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.

Operation time per day

	Annual average air temperature
	Under 30°C (86°F)	Over 30°C (86°F)
Over 8 hours	2 years	1 year
Under 8 hours	1 year	6 months
