If the signal bars on your COMMAND PRO are not lit, follow these steps to troubleshoot the issue:

1. Check Power Supply: Ensure that your COMMAND PRO camera has sufficient battery power. Replace or recharge the batteries if they are low.

2. Verify Coverage Area: Confirm that the camera is installed within an area with adequate cellular network coverage. If you are in a remote area, consider moving the camera to a location with a stronger signal.

3. Restart the Device: Turn off your COMMAND PRO for a few minutes and then turn it back on. This can refresh the device's connection to the network.

4. Check SIM Card: Ensure that the SIM card is properly inserted and functional. Sometimes, a faulty or improperly seated SIM can lead to no signal being detected. If possible, test the SIM in another device to confirm it works.

5. Reset Network Settings: Sometimes, resetting network settings can help resolve issues with signal detection. Look for this option in the device settings menu, and follow the prompts to reset.

6. Display Status Bar Network Speed: Ensure your display settings are set to show the network speed indicator, which may provide insight into connection issues. This can help you determine if the device is connected without showing signal bars - learn more.

7. Update Firmware: Check if there are any firmware updates available for your COMMAND PRO. Updating the firmware can resolve bugs that might be affecting signal detection.

8. Factory Reset (if necessary): If the signal bars remain unlit, consider performing a factory reset on the camera. This should be a last resort as it will erase all settings and data.

9. Customer Support: If none of these steps resolve the issue, contact customer support for your COMMAND PRO. They may have additional troubleshooting steps or may need to replace the device if it is faulty.

By following these steps, you should be able to troubleshoot why the signal bars on your COMMAND PRO are not lit. If you continue to have issues, professional support may be required - learn more - learn more - learn more.
