Backup Function
*1 To prepare for when the battery dies, the contents of RAM (internal relays, shift registers, counters, and data registers) can be saved to non-
volatile memory. For how to save the contents of RAM, see "SD Memory Card" on page 11-1.
*2 The battery is primarily consumed by backup current while unpowered. However, the ambient environment (temperature and humidity) while
unpowered and powered also affects consumption. In particular, battery life is greatly reduced in a high-temperature and high-humidity
environment, so replacement is recommended every year when the effect of the ambient environment (temperature and humidity) while
unpowered and powered is included.
*3 Replacement while powered and replacement while power is supplied from the USB bus are also possible. For the replacement method, see
"Replacing the Backup Battery" on page 3-34.
