Sensor Alerts Quick Reference


Device: MiniMed® 670G insulin pump (MMT-1780K)

This table shows some of the most common alerts that you may receive when using Continuous Glucose Monitoring (CGM).

NOTE: To silence an alert, press Down, and then press Select on the desired option.

Alert Reason Steps to Take
Alert on high Sensor glucose (SG) value is equal to or higher than the high limit that you set. Do not treat your glucose based on SG. Confirm it using your Blood Glucose (BG) meter. Treat if necessary based on instructions from your healthcare professional and continue to monitor.
Alert on Low Sensor glucose value is equal to or lower than the low limit that you set. Do not treat your glucose based on SG. Confirm it using your BG meter. Treat if necessary based on instructions from your healthcare professional and continue to monitor.
Alert before high Sensor glucose reading is expected to reach the high glucose limit in the length of time you set for the Time before high. Do not treat your glucose based on SG. Confirm it using your BG meter. Treat if necessary based on instructions from your healthcare professional and continue to monitor.
Alert before low Sensor glucose reading is expected to reach the low glucose limit within 30 minutes. Do not treat your glucose based on SG. Confirm it using your BG meter. Treat if necessary based on instructions from your healthcare professional and continue to monitor.
Rise Alert Sensor glucose reading is increasing at a rate that is equal to or faster than the Rate Limit that you set. Do not treat your glucose based on SG. Confirm it using your BG meter. Treat if necessary based on instructions from your healthcare professional and continue to monitor.
Calibrate now A calibration is needed in order to receive sensor glucose readings. Enter BG value into your pump to calibrate.
Lost sensor signal Communication between pump and transmitter has been lost for 30 minutes during or after warmup. Check that the sensor is still inserted in the skin and the transmitter and sensor are still connected. Move your pump closer to your transmitter.
Calibration not accepted You system was unable to use the BG meter reading you entered to calibrate your sensor. In 15 minutes, your pump will prompt you to enter a new BG meter reading for calibration. Wash your hands and dry thoroughly before checking BG.
BG not received The transmitter was unable to receive the calibration BG reading from the pump. Move your pump closer to your transmitter and select OK. The pump will try sending the BG again.
Sensor expired Sensor has reached its maximum usage of 7 full days. Remove the sensor and follow the instructions for inserting and starting a new sensor.
Sensor updating The sensor is updating. Do not calibrate unless notified. This could take up to 3 hours.
Change sensor You have received two calibration not accepted alerts in a row. Remove the sensor and follow the instructions for inserting and starting a new sensor.
Cannot find sensor signal The pump has not received a signal from the transmitter. Disconnect and reconnect your transmitter and sensor and select OK.
