There are various possibilities here. Is the caritag located in a building or vehicle? Although GPS satellites are very accurate, they also have their weaknesses, which can lead to incorrect location determination or loss of signal from the caritag. For example, GPS may only work to a limited extent or not at all indoors or in closed rooms without a clear view of the sky. Is the caritag correctly charged and switched on? Can it establish a connection via GPS or UWB? Check the symbols next to the battery indicator. Sometimes it can take a few minutes for the caritag to receive a signal. Try to move in different directions and try not to hold the caritag horizontally. If the problem persists, please contact our support team at service@caritag.com.
