It means that you need to replace the battery. Search for similar threads, I sure that there are more than one.
If the clock falls back whenever the power is off, then it's the CR2032 located on the CPU card. Take very good notes on the where the wires go if you remove the CPU to change the battery. Don't forget to change the time & date afterwards.
