Before programming System Data, the battery must be installed in
CN6 to allow memory retention when a power failure or brownout
occurs. When a brownout or power failure occurs, and the battery
backup circuit is not activated, Time and Date, Terminal status (e.g.,
MIC), and SMDR Data are reset. System data is not lost due to the
battery backup circuit.
When a CPUII( )-U10 ETU is installed and the system or battery
backup fails for any reason, the clock/calendar must be set. The fully
charged battery retains memory for approximately three years.
