Looks like this is for an IQ Panel 4, is that right?
If you are having trouble getting the initial cell connection to begin, there are some typical troubleshooting steps that usually help resolve the issue.
First try a reboot of the panel. Settings > Advanced Settings > Reboot Panel. Wait about 5 minutes after boot up, then run another cell test.
If there is no improvement, make sure the system is connected to wifi and update the firmware by the steps linked below. You may need to update incrementally depending on how old your firmware is.
