The question marks mean that the transmitter does not understand the sensor readings for the moment. You will want to wait a minimum of 3 hours for them to clear. If they do not clear within that time frame, please contact your local distributor for assistance.
Turn your smart device sideways. The landscape view lets you see up to the last 24 hours of sensor readings and, if you entered Events, your Event markers.
The “Bluetooth is off” alert means this function is turned off. Bluetooth must be on in order to get glucose information on your device. Refer to your smart device guide to turn on your Bluetooth.
This screen means you recently entered a calibration blood glucose value and the sensor is having trouble calibrating. Follow the directions on the screen to enter a fingerstick reading in 15 minutes to restore readings.
This icon means you need to enter a calibration and will appear when it is time for your 12-hour calibration update, or any other time an additional calibration is needed.
