The panel time, location, some service provider data, etc., has all failed to sync. The initial cell connection commands failed and the cell radio is not responding. The location and time, etc., will be resolved once the underlying connection issue is fixed.
Can you verify the option selected for Q7 in panel programming? It should be 1.
Turn off wifi on the GC3.
Power off the panel completely, unplug AC first, then battery. Open the cell tray and pull out the cell sled. Can you take a photo of that sled’s label and send it as a PM?
Reinsert the cell sled carefully and make sure it is firmly installed.
After power up, do not turn on wifi yet, first wait about 5 minutes then run two back to back cell tests. Any change in response?
