• What does the solid Red LED on my CEL-FI GO mean?

  A solid Red LED indicates a hardware error where the unit is not booting up normally. You should try unplugging and reinserting the power. If the issue persists, contact support.

• How do I switch my CEL-FI booster between Mobile and Stationary modes?

  You can switch modes using the CEL-FI WAVE app. Go to the Settings tab, select Booster Settings, and toggle between Mobile and Stationary modes. Ensure the mode matches your application for regulatory compliance.

• What is the CEL-FI WAVE app used for?

  The CEL-FI WAVE app is a management platform available for iOS and Android. It allows you to register your device, set up antennas, change carriers or modes, and view real-time system performance and signal gain metrics.

• Why is the LED blinking green continuously?

  A blinking green LED means the unit is scanning for networks to boost. If it continues indefinitely, ensure both antennas are connected properly and that the selected operator signal is available at your location.

• Where should I install the Donor Antenna?

  The Donor Antenna should be installed where the cellular signal is strongest, typically near a window or outdoors. It must be isolated from the Server Antenna to prevent oscillation and should be free of obstructions.
