These daily tips can help you take care of your insulin pump so it takes care of you!

  1. Keep it secure: If your pump touches your skin, turn the buttons away from your body to reduce long term moisture exposure. Consider a waist pouch while exercising.
  2. Soft button pushing: When pushing the buttons on your pump, use the side or pad of your finger. Try to avoid sharp objects like keys or the tips of long or acrylic fingernails.

The Temporary Basal Rate feature lets you immediately increase or decrease your basal insulin for the period of time (duration) that you set. It is often used for exercise and sick days. A Temp Basal can be set in either Percent (delivers a percent of the current basal rate) or by Rate (delivers the amount that you enter). Follow these pump screen instructions.

To learn about how to use the Bolus Wizard calculator and advanced bolus options like the Dual Wave and Square Wave feature, refer to this Getting Started Guide.

If your pump clip breaks, you can request a replacement at no charge online by logging into your account. Limitations apply.

Suspend on low is a feature that is used in conjunction with continuous glucose monitoring (CGM). If the feature is turned on, the pump automatically suspends insulin infusion for up to 2 hours when glucose levels reach a pre-determined threshold. After 2 hours, the pump resumes basal insulin delivery. If blood glucose (BG) is still low 4 hours after resuming basal, insulin delivery re-suspends.

When Suspend on low occurs, all insulin delivery is stopped immediately. Your pump alarms and the screen displays an alarm message. Insulin will remain suspended. If the Suspend on low alarm is not cleared after 2 minutes:

  • the pump will begin to siren
  • this emergency message will appear on the pump screen

This will continue until the alarm is cleared.

If you clear the alarm within 2 hours:

  • insulin will stay suspended for a maximum of 2 hours unless you manually resume insulin delivery
  • basal insulin will then resume and will not suspend again for the duration of time determined by your Low Snooze setting
  • after this time has passed, insulin will then be suspended again if sensor glucose is at or below the low limit

If you do not clear the alarm:

  • insulin delivery will remain suspended for 2 hours
  • basal insulin will then resume automatically and will not suspend again for 4 hours regardless of your sensor glucose value
  • if you clear the alarm during the 4-hour period, the time before insulin can be suspended again will be reduced to equal the duration of your Low Snooze setting

There are two ways insulin can be restarted when Suspend on low occurs: automatic and manual resume.

Automatic: Basal insulin will automatically resume if insulin has been suspended for the maximum of 2 hours. You will always receive a Basal delivery resumed alert when this occurs.

NOTE: Any bolus that was delivering at the time the Suspend on low occurred will not restart. The basal pattern active at the time the Suspend on low occurred will restart. If a Temp Basal was active at the time of the suspend, the Temp Basal will not resume if the Suspend on low alarm was not cleared. If the Suspend on low alarm was cleared, the Temp Basal will resume if there is still time remaining.

Manual: There may be times when you choose to resume basal insulin delivery yourself. You can simply take these steps to manually resume basal insulin delivery:1) Select Suspended on low. 2) Press Resume Basal. 3) Press Yes to confirm.

NOTE: Any bolus that was delivering at the time the Suspend on low occurred will not restart. The basal pattern active at the time the Suspend on low occurred will restart. If a Temp Basal was active at the time of the suspend, the Temp Basal will not resume if the Suspend on low alarm was not cleared. If the Suspend on low alarm was cleared, the Temp Basal will resume if there is still time remaining.

Calibrating Sensor

  • Try not to calibrate with multiple blood glucose (BG) meters. It’s best to stick with the same meter for all your calibrations.
  • We recommend calibrating 3-4 times a day.
  • Wash your hands before checking your BG.
  • Enter the BG reading into the pump right away. Don’t use old meter BG readings or previous sensor readings as a calibration.
  • If your system requires a new calibration, wait at least 15 minutes between calibration entries.

You should calibrate when your glucose levels are stable. Exercise and eating can cause rapid changes in your glucose levels. That’s why many people choose to calibrate before meals and before bedtime.

You can use the Calibration Reminder to give you notice before the next calibration is necessary. For example, if you calibrated at 7:00 a.m. your next calibration would be due at 7:00 p.m. (12 hours later). If your reminder is set for 1 hour, you would receive a Calibration Reminder at 6:00 p.m. which is 1 hour before the calibration is due. This can help ensure you calibrate 3-4 times a day. The Calibration Reminder defaults On with a reminder time of 1:00 hour.

To change the Calibration Reminder:

  1. Go to: Main Menu > Options > Reminders > Calibration

  2. Select Reminder to turn the reminder on or off.
  3. If you turn on the reminder, select Time and enter a time between 5 minutes and 6 hours.
  4. Select Save.

CGM alerts & alarms

Your pump has a feature called Alert Silence, where you can temporarily silence your alerts. To use the Alert Silence feature:

  1. Go to: Main Menu > Audio Options > Alert Silence Options
  2. Select All Sensor Alerts or your desired alerts
  3. Select the Duration (time) you want
  4. Select Begin

Don’t worry, you will still get important low alerts if Alert Silence is ON. For your safety, Low SG (50 mg/dL or below) will always sound, and Alert on Low will sound if turned on.

You can cancel the Alert Silence feature at any time:

  1. Go to: Main Menu > Audio Options > Alert Silence
  2. Select Cancel Alert Silence

Alerts with the system are customizable. You can adjust your low, high, and calibration alert settings. Be sure to work with your healthcare provider who can help you determine how to optimize your settings.

Taping & securing your sensor

The MiniMed 630G system uses the Guardian Sensor 3 and can be worn on the abdomen. Watch this video for help.

We have a recommended method for taping that we have found is effective for most people who wear CGM. It requires you to use two pieces of oval tape that are supplied with your sensor. Some people also use an additional layer of tape called overtape. Watch this video on how to tape and use extra adhesives. For more information on tape tips and site management, click here.

You can purchase adhesives and tapes at www.Diabetes.Shop or through the product manufacturer’s website – a full list of product recommendations can be found here.

Contact 24-Hour Technical Support at 1-800-646-4633 option 1 for technical assistance or to report product issues. They can also provide a sample kit with various tapes and adhesives.

Requesting a replacement sensor

Please sign in to your online account to complete the sensor replacement form. (We recommend getting your sensor lot number ready before you begin the process.)

Even if you have an online Medtronic account, a unique login is needed for CareLink software. Learn how to create a CareLink account.

The CareLink uploader allows you to upload the information in your pump or meter to the CareLink website. Learn how to set up CareLink on your computer.

Check out the Upload Guide for easy steps for your first or next pump upload. You can always watch this video.

Tips for traveling

Pack extras of everything– insulin, infusion sets, sensors, reservoirs, alcohol swabs, sensor tape, extra compatible batteries for your pump, and even syringes in cases of emergency. The mentality is, “it’s better to have more of what you need, than not enough.” Check out our full travel checklist here.

The TSA allows for diabetes-related supplies, equipment and medication—including liquids—through the checkpoint once they have been properly screened by X-ray or hand inspection.

If possible, pack all your supplies together in your carry-on bag so you have everything on hand. Before your screening begins, inform the officer conducting the screening about any supplies on you or in your carry-on.

The Travel Loaner Program allows US-based customers to take a "back-up" insulin pump for a $50 fee every 90 days. Take a "back-up" pump when you:

  • Go on a cruise
  • Travel to Hawaii or Alaska
  • Travel internationally

Complete the Travel Loaner form and submit it at least 2 weeks prior to your trip to ensure on-time delivery. A signature is required upon delivery and you will need to return the travel loaner when you arrive back home.

It is important that you check your blood glucose (BG) more frequently while you are traveling. The routine hassle of travel, including stress, changes in time zones, schedules and activity levels, meal times and types of food, can all affect your diabetes control. Be extra attentive to monitoring your BG frequently and be prepared to respond if needed.

Note: The Travel Loaner Program only includes insulin pumps and does not include blood glucose meters or CGM devices.

Check out additional information and how to apply for a travel loaner pump.

Important Safety Information: MiniMed 770G System With SmartGuard Technology
The MiniMed 770G system is intended for continuous delivery of basal insulin (at user selectable rates) and administration of insulin boluses (in user selectable amounts) for the management of type 1 diabetes mellitus in persons two years of age and older requiring insulin as well as for the continuous monitoring and trending of glucose levels in the fluid under the skin. The MiniMed 770G System includes SmartGuard technology, which can be programmed to automatically adjust delivery of basal insulin based on continuous glucose monitoring (CGM) sensor glucose values (SG) and can suspend delivery of insulin when the SG value falls below or is predicted to fall below predefined threshold values.

The Medtronic MiniMed 770G System consists of the following devices: MiniMed 770G Insulin Pump, the Guardian Link (3) Transmitter, the Guardian Sensor (3), one-press serter, the Accu-Chek® Guide Link blood glucose meter, and the AccuChek®Guide Test Strips. The system requires a prescription.

The Guardian Sensor (3) has not been evaluated and is not intended to be used directly for making therapy adjustments, but rather to provide an indication of when a fingerstick may be required. All therapy adjustments should be based on measurements obtained using a blood glucose meter and not on values provided by the Guardian Sensor (3).

All therapy adjustments should be based on measurements obtained using the Accu-Chek® Guide Link blood glucose meter and not on values provided by the Guardian Sensor (3). Always check the pump display to ensure the glucose result shown agrees with the glucose results shown on the Accu-Chek® Guide Link blood glucose meter. Do not calibrate your CGM device or calculate a bolus using a blood glucose meter result taken from an alternative site. It is not recommended to calibrate your CGM device when sensor or blood glucose values are changing rapidly, e.g., following a meal or physical exercise.

WARNING: Do not use the SmartGuard Auto Mode for people who require less than 8 units or more than 250 units of total daily insulin per day. A total daily dose of at least 8 units, but no more than 250 units, is required to operate in SmartGuard Auto Mode.

WARNING: Do not use the MiniMed 770G system until appropriate training has been received from a healthcare professional. Training is essential to ensure the safe use of the MiniMed 770G system.
