Alerts & Alarms

Alerts & Alarms

Listed below are alerts, alarms and reminders you may encounter while using your device.

a (alarm)

Reason: This alarm shows the letter A followed by two numbers. A-alarms cause all insulin delivery to stop until the alarm is cleared. Your insulin pump settings are retained. However Guardian settings are reset.

Action: If this alarm repeats often, call your local Medtronic Rep.

alert silence alert

Reason: Displays when one or more glucose alerts occur during the time that the Alert Silence feature is turned on.

Action: Press ESC, then ACT to clear the alert. Check the SENSOR ALERT HISTORY screen for the recorded glucose alert information. To view SENSOR ALERT HISTORY:

  1. Go to the SENSOR ALERT HISTORY screen:
    • Home Screen > Main Menu > Sensor > Sensor Alert History
  2. The SENSOR ALERT HISTORY screen appears. The most recent alert is highlighted. Select the alert you want to get more information on, then press ACT.
  3. A new screen will appear with the alert details.
auto off alarm

Reason: Alerts you that no buttons were pressed during the time limit you set for the AUTO OFF DURATION feature, and so insulin delivery has been stopped.

Action: Press ESC, then ACT to clear the alarm.

bad sensor alert

Reason: You may receive this alert after you receive two Cal Errors in a row, without Cal Errors, or when initializing your glucose sensor.

Action: If the alert resulted from two Cal Errors in a row, replace the glucose sensor.

If the alert happened without two Cal Errors, use the transmitter's tester to make sure your transmitter is working properly.

If you received this alert during initialization, you may be able to resolve this alert without replacing your glucose sensor. Call your local Medtronic Rep. for further assistance.

bad transmtr alert

Reason: The transmitter battery is depleted.

Action: Recharge your transmitter immediately.

batt out limit alarm

Reason: Occurs if the battery has been out of the insulin pump for more than five minutes or out of the CGM monitor for more than ten minutes.

Action: 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.

bolus stopped alarm

Reason: Occurs if the battery cap is loose or the insulin pump was bumped or dropped during a bolus. It can also happen if the insulin pump receives a static shock. As a safety measure, the insulin pump stops the bolus when this happens.

Action: If you dropped your insulin pump, visually inspect it to make sure it is not damaged in any way. Then check BOLUS HISTORY to review how much of the bolus was actually delivered. If necessary, reprogram a bolus with the amount not yet delivered.

button error alarm

Reason: Occurs if a button has been continually pressed for more than three minutes.

Action: Press ESC, then ACT to clear the alarm. Adjust where your insulin pump/CGM monitor is located if it is pressing up against something to cause the alarm. If you followed these steps and you receive another BUTTON ERROR alarm, call your local Medtronic Rep.

Buttons not responding

Reason: The monitor experienced a hardware or software error that prevents the monitor buttons from working.

Action: Restart the monitor by unplugging it from the power supply, waiting 10 minutes, and then plugging it back into the power supply.

cal error alert

Reason: An error occurred when entering a new meter blood glucose (BG) measurement to calibrate the system. Some possible causes are:

  • An incorrect blood glucose number was entered from the meter into the insulin pump/CGM monitor.
  • The entered blood glucose measurement was not current.
  • Your blood glucose is rising or falling rapidly.
  • The glucose sensor needs more time to stabilize after being inserted.
  • The glucose sensor is no longer reading the glucose sensor correctly.

Action: If you receive a Cal Error, enter a new BG meter reading for calibration. If you receive a Cal Error on your second calibration, a CHANGE SENSOR alert will occur on a Revel or Guardian System and a BAD SENSOR alert will occur on a 722 insulin pump model. Call your local Medtronic Rep. for further assistance.

change sensor alert

Reason: You may receive this alert after you receive two Cal Errors in a row, without the Cal Errors, or when initializing your glucose sensor.

Action: If the alert resulted from two Cal Errors in a row, replace the glucose sensor.

If the alert happened without two Cal Errors, use the transmitter's tester to make sure your transmitter is working properly.

If you received this alert during initialization, you may be able to resolve this alert without replacing your glucose sensor. Call your local Medtronic Rep for further assistance.

charge transmtr alert

Reason: The transmitter battery is depleted.

Action: Recharge your transmitter immediately.

check settings alarm

Reason: Occurs after an E alarm or after you clear your insulin pump/CGM monitor. It is advising you to make sure that all your settings are correct.

Device Error

Reason: The monitor experienced a hardware or software error.

Action: Restart the monitor by pressing the silence icon, which looks like a bell (equipment interference).

e (error) alarm

Reason: An E-error alarm will show the letter E followed by two numbers. E-alarms cause all insulin delivery to stop, the insulin pump/CGM monitor resets, and all your settings are cleared.

Action: After receiving this alarm, note the error number then call your local Medtronic Rep for further assistance.

empty reservoir alarm

Reason: There is no insulin in the reservoir.

Action: Change the reservoir immediately.

failed batt test alarm

Reason: The insulin pump/CGM monitor tests the voltage of each battery installed. This test ensures a battery with low voltage is not used. If the battery does not have enough voltage, this alarm will occur. The insulin pump/CGM monitor will not function and the battery must be replaced.

Action: Install a new battery into the insulin pump/CGM monitor.

fall rate alert

Reason: The sensor glucose measurements are falling at a rate that is equal to or faster than the Set Fall Rate Limit you selected for the alert. The insulin pump/CGM monitor plays two consecutive tones, in falling pitch, if an audible beep has been selected as the alert type.

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

finish loading alarm

Reason: You have not completed filling the infusion set with insulin.

Action: Press ESC, then ACT to clear the alarm. This resumes basal delivery. Review these tutorials.

high predicted alert

Reason: The sensor glucose measurements may reach or go above your High Glucose Limit in the length of time you selected for the High Predictive alert. The insulin pump/CGM monitor plays three consecutive tones, in rising pitch, if an audible beep has been selected as the alert type.

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

high sg alert

Reason: The glucose number is higher than or equal to your high glucose limit. If you do not set a High Glucose Limit and do not set the glucose alerts ON, then you will not get a High SG alert.

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

high xxx mg/dl (xxx = sg measurment) alert

Reason: The sensor glucose number is higher than or equal to your high glucose limit. If you do not set a High Glucose Limit and do not set glucose alerts ON, then you will not get a high sensor glucose alert. The insulin pump plays four consecutive tones, in rising pitch, if an audible beep has been selected as the alert type.

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

is priming complete? alarm

Reason: If you manually prime your insulin pump with more than 30 units of insulin, this message appears.

Action: 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.

Action: Install a new alkaline battery in the insulin pump/CGM monitor.

weak signal alert

Reason: Occurs when the insulin pump/CGM monitor does not receive data from the transmitter for a pre-defined period of time (as set in Weak Signal for Revel and Missed Data for 722 insulin pump models and Guardian).

Action: Move the insulin pump/CGM monitor closer to the transmitter or move the transmitter and the insulin pump/CGM monitor to the same side of your body.

Reducing/silencing alarms

Is there anything I can do to reduce the number of alarms I get?

It is important to remember that each alarm serves a meaningful purpose and is telling you about something, so you do need to pay attention to the number and type of alarms you receive. You can reduce the number of alarms you get, by adjusting your user settings or by turning some of the alarms/alerts off. For example, you can change your high and low alarm thresholds to levels that are appropriate for you. In addition, you can disable the "high glucose" alarm when you know you are going high. Another example is to adjust the time duration of the "snooze alarm" so that you receive fewer reminders. Other alarms can be avoided by taking action before they occur, such as doing your calibration on a regular schedule and keeping your transmitter within 6 feet (2 meters) of the insulin pump so that synchronization is not lost. Your HCP should be consulted before making adjustments to alert settings on the pump for safety

What if I want to have silent alerts?

You can choose to set the alerts to the vibrate function instead. You'll find this in the Utilities Menu by first selecting Alarm Menu, then selecting Alert Type to choose between beep or vibrate. Or you can silence them for a period that may be useful when you are in a meeting or in an exam.
You'll find this in the Sensor Menu in the Alert Silence option.

Setting alarms

How do I set the alerts/alarms on my Minimed® Veo™ System?

You can set a number of alerts, such as reminders for calibration, BG readings and missed meals.If you are using the CGM function of your pump then you can set high/low glucose alerts, predictive high/low glucose alerts, rate of change alerts and Snooze alerts for any of these alarms. You can also turn on the Low Glucose Suspend feature.

Your healthcare professional will advise and help you to set up the alarms and alerts on your Minimed® Veo™ System.

I have programmed my new / replacement pump and got a reprogram/check settings alarm, what does this mean?

The Check Settings Alarm occurs 5-10 minutes after resetting the pump without resetting the time/date. The pump will need to rewind and all settings (time/date/basal rates) need to be verified.
