4-2-1 Notification that the battery needs to be replaced
This Battery life counter function notifies you with LED display and beep sound when the
battery needs to be replaced.
The battery life is determined by the counter function. The battery life counter operates
while commercial power is supplied after shipment. (When the ambient temperature of the
battery is higher than 25°C, the value of the counter will be incremented at a faster pace.)

storage/use environment and backup frequency.
The nearer the end of the life is, the more rapidly deterioration proceeds.

of the battery.

the shorter battery life.
