How to Turn Off a Medtronic 780G Insulin Pump

To turn off a Medtronic 780G pump, press and hold the Select button for 3+ seconds, then choose Suspend Delivery > Stop Pump. For a full shutdown, remove the battery. Always check blood glucose levels afterward, as insulin delivery halts immediately.

Step-by-Step Shutdown Guide

Temporary Suspension (Insulin Stops, Settings Saved):
- Press and hold the Select button for 3+ seconds.
- Navigate to Suspend Delivery > Stop Pump.
- Confirm by selecting Yes.
Full Power-Off (Complete Shutdown):
- Open the battery compartment (slide the back cover).
- Remove the battery for 10+ seconds to power down fully.
- Reinsert the battery to restart (if needed).

Key Warnings Before Turning Off

No insulin delivery: Blood glucose may rise rapidly. Monitor levels closely.
Alarm triggers: The pump may alert for "Missed Bolus" or "Suspended Too Long."
Data loss risk: Full power-off may clear unsaved history (e.g., temporary basal rates).
Restart delay: Rebooting takes ~2-5 minutes; carry fast-acting glucose.

Comparison: Suspend vs. Full Shutdown

Action	Insulin Delivery	Settings Retained	Restart Time	Use Case
Suspend Delivery	❌ Stopped	✅ Yes (resumes when restarted)	Instant	Short breaks (e.g., shower, exercise)
Full Shutdown	❌ Stopped	⚠️ Partial (may lose temp basal)	2-5 minutes	Long-term storage, troubleshooting
Remove Cartridge	❌ Stopped	✅ Yes (but requires re-prime)	5-10 minutes	Cartridge replacement

Troubleshooting If Pump Won't Turn Off

Frozen screen: Hold Select + Up Arrow for 10 seconds to force reboot.
Unresponsive buttons: Remove/reinsert the battery to reset.
Error codes: Note the code (e.g., "E12") and consult the user guide for specific steps.
Battery issue: Replace with a fresh AAA alkaline battery (lithium may cause errors).

What to Do After Turning Off

Check blood glucose immediately and every 1-2 hours.
Use backup insulin (pens/syringes) if offline >1 hour.
Re-prime the pump if the cartridge was removed.
Calibrate CGM if sensors were disconnected.
