What can I do if my Dexcom G5 Mobile sensor fails during the 2-hour warm-up?
You should first ensure that your Dexcom G5 Mobile sensor was correctly inserted:
- Did you clean your sensor site with a topical antimicrobial solution, such as isopropyl alcohol and the transmitter with a damp cloth or alcohol wipes?
- Did you keep the safety lock on the sensor applicator until AFTER the sensor applicator was secure to your skin?
- Did you keep your fingers ABOVE the collar when pushing the white plunger completely down the applicator barrel?
- After pressing the white plunger completely down the applicator barrel, did you then move your fingers to BELOW the collar and pull the collar completely up the applicator barrel?
- Is the transmitter serial number correctly entered into the receiver or compatible smart device?
- Is the transmitter completely snapped into the transmitter holder on the sensor?
While in 2-hour warm-up, the CGM system may detect that your sensor is unable to retrieve glucose information once the session starts. At this time, the warm-up period will end and your receiver or compatible smart device will display the “Sensor Failed” screen. You will now need to replace the sensor.
