(Error 12) Self-Test Failed
During a system check a part of your Signal Booster’s configuration has reported less than optimal performance. The system could be displaying a non-critical error message. If you have a boost in cellular service at your service antenna you can ignore the E12 message. If you do not have boosted signal, check to confirm that both your service antenna and donor antenna are properly connected and functional. If the antennas checkout, the boost number on the Signal Booster is high and you still don’t have a boosted signal try restarting the Signal Booster.
If you recently updated the software of your device, try again. If the error persist please contact your point of sale for further assistance.
