This is probably a tech support call however I always like to inquire here first to see if anyone has had the same issues with a fix or can point out my errors.
Since upgrading my old ION the clock is always 2 hours behind after shut down and restart. My experience with CMOS bats is the time and date go way bonkers when the bat is bad and not routinely 2 hours behind.
The time zone is set to Pacific since I am Los Angeles.
Hey Jeff! Is your console on a network? Or do you use only hard-line DMX out the back?
Is there anything else on your network other than the Ion, Xe, and node?
