New Quolsys Panel 2 Plus System with "Panel Low Battery"

I have a new Quolsys Panel 2 Plus system that was fairly recently installed. This morning it is showing a “Panel Low Battery”. Is this common for a brand new system? Do I have a defective battery?

Often panels are shipped with the battery unplugged. If you open the panel, is the battery plugged in? If not, plug it back in. The internal battery can take a few hours to fully charge.

If the battery is plugged in when you check, is the panel plugged in via the transformer and is the outlet working?
