You may use your System while on an aircraft, following any requests from the flight crew. You can continue to get Sensor glucose readings and alarms after you put your phone in airplane mode, as long as Bluetooth is enabled.

IMPORTANT: Glucose alarms will not be issued while your phone is in airplane mode unless you enable Bluetooth.

Some airport full-body scanners include millimeter-wave radio technology, which you should avoid exposure to your Sensor. The effect of these scanners has not been evaluated, and the exposure may damage the Sensor or cause inaccurate results. 

To avoid removing your Sensor, you may request another type of screening. If you do choose to go through a full-body scanner, you must remove your Sensor.

The Sensor can be exposed to common electrostatic (ESD) and electromagnetic interference (EMI), including airport metal detectors. You can keep your Sensor on while going through these.
