7.3.7 Low RTC battery
The lithium battery for the display function of the date/time is installed in the SCU-1600. "Low RTC
Battery" is displayed when the decrease in the voltage of the battery is detected.
The STP pump can operate though some failure occurs such as the time of the error history is not
correct when the voltage of the battery is low.
"Low RTC Battery" message cannot be released without exchanging the battery.
Contact us when exchanging the battery. The decomposition of the SCU-1600 is necessary.
