Important Safety Information

At Medtronic, we are committed to continually evaluating and improving the quality and reliability of our products and services. Through our monitoring system, we have learned about potential issues and we would like to inform you about these and provide recommendations regarding the usage of our pumps.


Sensor Graph Timeout Safety Information for MiniMed™ Veo™ Pumps (MMT-554 and MMT-754 only) with sensor usage and Low Glucose Suspend feature enabled

Your MiniMed™ Veo™ insulin pump allows you to set the number of minutes to display the Sensor Graph before returning to the home screen.

The factory default setting for Sensor Graph timeout is set to 2 minutes. If the Sensor Graph timeout is set to “NONE” it can prevent the auto-resume of basal delivery 2-hours after a Low Glucose Suspend event, which can result in elevated blood glucose values.

[This will only happen if you go to the Sensor Graph screen during a Low Glucose Suspend event, and leave that screen displayed and if the Sensor Graphic Timeout is set to “NONE”]

When this happens, the pump will beep 3 times every 15 minutes to remind you that insulin delivery has been suspended. All other alarms will function normally, but basal delivery will not resume as long as the Sensor Graph screen is displayed.

Sensor Graph Timeout Recommendations:

  • Do not change the Sensor Graph timeout setting to “NONE”.
  • If you are using the Low Glucose Suspend feature and have changed the Sensor Graph timeout setting to “NONE”, reset it by following the steps below:
    1. Go to the Sensor Menu
    2. Select Edit Settings, Press ACT
    3. Select Graph Time Out, Press ACT
    4. Select 2, 4 or 6 minutes (do not select “NONE”), Press ACT

You can find the insulin pump model in the status screen or on the label on the back of the insulin pump.

This feature allows you to select how long the Sensor Graph screen will stay displayed after you have stopped pressing the button. The MiniMed™ Veo™ is shipped from the factory with the default setting of 2 minutes. The options available in the settings menu are 2 minutes, 4 minutes, 6 minutes, or “NONE”.

This option is a convenience for people who do not want the Sensor Graph screen to stay displayed. Because it can affect the function of the Low Glucose Suspend feature, we do not recommend it.

There is not an alarm that occurs at the end of the 2 hour period. However, whenever your pump is suspended, it will beep 3 times every 15 minutes to remind you that no insulin is being delivered. All the pump and sensor alarms and alerts will work while the pump is displaying the Sensor Graph screen.

This behaviour will not occur unless your Sensor Graph Timeout setting is set to “NONE” and you use the Low Glucose Suspend feature (on the MiniMed™ Veo™ insulin pump).

If you are not sure of your Sensor Graph Timeout setting:

  1. Go to the Main Menu
  2. Select the Sensor Menu
  3. Select Edit Settings, Press ACT
  4. Select Graph Timeout, Press ACT
  5. Select 2, 4 or 6 minutes (do not select “NONE”), Press ACT

The pump is designed to withstand occasional drops or bumps, however when this happens it is recommended to check the pump for cracks or damage. We have learned about some users having experienced issues with the drive support cap of the pump and we want to proactively inform our customers how to avoid experiencing similar challenges. The pump’s drive support cap holds the pump motor in place and allows the motor’s piston to press against the reservoir to deliver insulin.

In rare cases, the cap may stick out from the bottom of the reservoir compartment. This condition can occur when the pump is damaged due to impact with a hard surface (for example if it is dropped). If the loose drive support cap is pressed, it could result in the unintended delivery of additional insulin.


  • Regularly examine your pump especially after a shock or drop on a hard surface.
  • If the drive support cap is sticking out, as shown in the photo above, do not press on this part of the pump and discontinue use of the pump.

Some customers have experienced a loose drive support cap, and in rare cases the cap may stick out from the side of the insulin pump as a result of impact with a hard surface. In most cases, the loose drive support cap will result in an A33 or Motor Error Alarm during the manual prime/fill tubing process. While the risk to you is low, we’re asking you to examine the drive support cap on your insulin pump. To locate the drive support cap:

  • Hold the insulin pump with the screen facing you (the reservoir opening/Tube should be on the bottom of the left side.)
  • The drive support cap is the round circle on the bottom right side of the pump below the raised Medtronic MiniMed bumper label. IMPORTANT: DO NOT PRESS ON THIS PART OF THE INSULIN PUMP.
  • A normal insulin pump and an insulin pump with a loose drive support cap are shown in the pictures above.
  • Look at the drive support cap:
    • If drive support cap IS indented: Your drive support cap has not been impacted and you can continue to use your insulin pump.
    • If drive support cap IS NOT indented: You must discontinue use of the insulin pump. You will need to manage your diabetes with insulin injections, per the back-up plan provided to you by your healthcare professional and contact our Helpline.

The insulin pump’s drive support cap holds the insulin pump motor in place and allows the motor’s piston to press against the reservoir to deliver insulin.

AllMiniMed™ Veo™ insulin pump models may be affected. You can find the insulin pump model in the status screen or on the back label of the insulin pump.

Because your child’s safety and product quality are so important to us, your Medtronic insulin pump is manufactured to meet an international standard and requires durability against shock and drop.
If your child drops the insulin pump a lot, then periodically follow this standard insulin pump drop procedure:

To check for damage associated with a loose drive support cap follow this process:

Standard insulin pump drop procedure
Take care to protect your pump from being dropped.

  1. Check that all connections are still tightly in place.
  2. Check the LCD, keypad and pump case for cracks or damage.
  3. Check infusion set, including the tubing connector and tubing for cracks or damage.
  4. Review the status screen, basal rates and other pump settings.
  5. Perform the Self test procedure located in the UTILITIES MENU.
  6. Call your local Medtronic Diabetes representative for assistance.

As explained in the pump user guide of all MiniMed™ Veo™ insulin pumps, exposure to water may result in pump alarm, damage of the pump’s internal electronics or cause the buttons to stop working.

Our MiniMed™ Veo™ insulin pumps have an IPX7 rating, which means they can usually withstand an accidental dunk or splash but should not be immersed in water. This means the insulin pump meets the water standard of 1 metre (approximately 3 feet) for 30 minutes.

The MiniMed™ 640G insulin pump, when properly assembled with the reservoir and tubing inserted, is waterproof (watertight rating IPX8) at depth of up to 3.6 metres (12 feet) for up to 24 hours.

Your insulin pump is designed to resist accidental contact with liquids which includes insulin as well as water. If your insulin pump has been exposed to insulin, follow the same steps you would if it was accidentally exposed to water:

  1. Pat the outside of the case until dry.
  2. Open the reservoir compartment and check the compartment and reservoir for water. If wet, dry it completely within 10 minutes of exposure to water. Exposure to liquids, including water or insulin can corrode the mechanism.
  3. Dry the reservoir completely—do NOT place a wet reservoir in the insulin pump.
  4. Do not use hot air to dry your insulin pump. This may damage your insulin pump's internal electronics.
  5. Check the battery compartment and the battery—if wet, let them dry completely before using the insulin pump.
  6. Perform a Self-test procedure located in the utilities menu.

Constant exposure to moisture can damage your insulin pump. Here are some tips that are helpful in dealing with moisture:

Daily Activities

  • If you live in a humid place make sure to keep your insulin pump in an accessory that will cover it or in a pocket to protect it from the heat and sweat.
  • Stay mindful not to have the insulin pump exposed directly to areas on your body that may sweat the most.
  • If your hands tend to be sweaty, wipe them dry before you push your insulin pump buttons.

MiniMed™ Veo™ insulin pumps have an IPX7 rating, which means they can typically withstand an accidental dunk or splash but you should avoid immersing your pump in water.

While insulin pumps are designed and manufactured to be quite sturdy cracking is possible. Because we cannot prevent cracking with absolute certainty, we recommend that insulin pump users do not intentionally submerge their insulin pump in water.  Medtronic continuously works to improve product quality and features for both new and existing products. Feedback from customers like you plays a big part in that process. We will be sure to keep you informed on any improvements as they become available.
