If this alarm repeats often, call the Medtronic helpline.

Press ESC, then ACT to clear the alarm.

• If the alert resulted from two Cal Errors in a row, replace the glucose sensor.
• If the alert happened without two Cal Errors, please contact your helpline to make sure your transmitter is working properly.
• If you received this alert during initialisation, you may be able to resolve this alert without replacing your glucose sensor. Call the helpline for further assistance.

Verify that the insulin pump/CGM monitor time and date are correct. If not correct, go to the UTILITIES MENU and reset the date and time. For CGM users, follow the FIND LOST SENSOR procedure to re-establish communication with the sensor.

• If you receive a Cal Error, enter a new BG meter reading for calibration.
• If you receive a Cal Error, enter a new BG meter reading for calibration.
• Call your Medtronic helpline for further assistance. Note: If you have pump model x12, x15, or x22, please call your Medtronic helpline for assistance.

Read the message on the screen, then press ESC, then ACT to clear the alarm.

• If manual prime is complete, press ESC.
• If the manual prime is not complete, press and hold ACT until manual prime is complete.

Do not disconnect the transmitter from the sensor.

• Make sure that the glucose sensor is inserted correctly.
• Check the REVIEW SETTINGS screen to make sure that the transmitter ID entered into the insulin pump/CGM monitor matches the ID on your transmitter: Home Screen > Main Menu > Sensor > Review Settings
• Check the transmitter and sensor connection. Touch the inserted sensor at the back of the assembly to prevent movement and push the transmitter firmly:
• If you hear a click, wait 20 seconds and look for a green light on the transmitter flash for 10 seconds to confirm a good connection. If you see the green light, the alert was due to the transmitter and the sensor not being connected.
• If you hear a click, but do not see a green light on the transmitter, check to make sure that the transmitter is charged.
• If you do not hear a click when you check the connection, the alert was due to a transmission problem. Bring the insulin pump/CGM monitor closer to the glucose sensor and transmitter.
• Use the FIND LOST SENSOR function to find your glucose sensor: Home Screen > Main Menu > Sensor > Link to Sensor > Find Lost Sensor

Note: If you have pump model x12, x15, or x22, please call your Medtronic helpline for assistance.

The MiniMed™ Veo™ insulin pump can recognise when your glucose levels begin to fall using the CGM function of the pump and will sound an alert to warn you. 

You can then act on this to prevent a hypoglycaemic event. However, if you do not respond to this alert and the CGM recognises a dangerously low glucose level, another warning will sound. If, however, you are unable to respond to the warning for some reason, the pump acts quickly to suspend insulin delivery for 2 hours, helping to prevent the hypoglycaemic event from becoming any more harmful.

Complete the following steps:

1. Check to see if your infusion set has become clogged.
2. Check your blood glucose (BG) and follow your safety guidelines for treating high glucose if necessary.
3. Clear the alarm by pressing ESC and ACT. A screen appears with two choices: Resume and Rewind.
4. Make sure that there is insulin in your reservoir.
   • If you identified and fixed a kink in your tubing, select Resume.
   • If the reservoir is empty, select Rewind and change your reservoir and infusion set.
5. Monitor your BG closely.

If you followed these steps and you receive another NO DELIVERY alarm, call the helpline

Consider taking corrective action after confirming with a blood glucose (BG) meter reading.

You can also silence them for a period that may be useful for example when you are in a meeting or in an exam. You'll find this in the Sensor Menu in the Alert Silence option.
