Therefore, even if the battery voltage drop detection LED bs at power-on of the basic unit, it may turn OFF as the temperature in the basic unit rises while running. • The remaining capacity of a graphite fluoride lithium primary battery never recovers even if the ambient temperature is high. If the ambient temperature is high and the battery remaining capacity is low, the battery voltage may rapidly drop as the remaining capacity is consumed. In addition, as a result of moisture absorption for a long period, self discharge of a graphite fluoride lithium primary battery may rapidly increase from some point to cause a rapid drop of the battery voltage. • For the above reasons, if you confirm that the battery voltage drop detection LED bs or when more than ten years have passed since the date of shipment, promptly replace the basic unit following the steps described in "5-2 Actions to be Taken When Battery Voltage Drop is Detected" without turning off the power. • If the battery voltage continues to decrease with the main power OFF, more and more data of the built-in SRAM can be easily lost, which causes a memory backup error (retain memory loss) after the main power is turned ON. In addition, the calendar may be stopped or delayed.
