rtc and cmos ram are invalid?

Hello, just turned on an old NBX 100 with 4.1.23 and got "RTC and CMOS RAM are invalid" in the console logs when booting. It resets the date/time information at every reboot. How do I fix this? Replace the battery on call processor board?



Thank you.

Re: rtc and cmos ram are invalid?

yes, that is it. The battery is dead.

 





The battery is a Duracell DL2016.

Thank you for details.



I cannot find them in local stores. I hope Energizer 2016 will do the job just fine.
