Some of the most frequent calls we get to our Product Support team shows that Stuck Button Errors / Unresponsive Keypad’s is one of the most common issues insulin pump patients face.Here you’ll find some practical tips to prevent the Button Error/Unresponsive Keypad from happening:
First and the most common occurrence: your button error alarm is informing you that a button on your pump has been continuously pressed for 3 minutes. This usually happens when the pump is worn in a tight pocket and the button becomes pressed. What should you do? Below you will see the actions that you can take when you experience the Button Error alarm:
- 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 please contact our product support tea
Another reason why you could receive a Button Error alarm could be moisture exposure that happened to your pump. The best way how to prevent this is to wear your pump in a protective cover.
There are a number of websites online that produce accessories that help you attach your pump to your belt or other parts of your clothing or that provide protective covers to minimise situations like those describe above. Take a look at our Accessories Brochure for products available directly from Medtronic.
Finally, on some rare occasions during keypad buttons on the MiniMed™ 640G insulin pump may become temporarily unresponsive when the atmospheric pressure around the pump increases or decreases rapidly. This would most likely happen when traveling in an airplane during take-off or landing. If this happens, in most cases you may not even notice because the pump will resolve this on its own.
During this temporary situation, a button may be too difficult to press down or a button can look like it is pressed and stuck in that position.
- If you notice the keypad buttons are difficult to press down, the pump will continue to deliver your basal insulin. You may not be able to program a bolus or suspend delivery as the buttons temporarily will not press down, but this will resolve on its own, usually within 30 minutes.
- If a button is stuck in a pressed position, after three (3) minutes a “Stuck Button” alarm is triggered which suspends insulin delivery (including basal). You may not be able to clear the alarm as the keypad is unresponsive. In the rare situation where this continues for more than ten (10) minutes, the pump will begin to siren.
Once the alarm is triggered and insulin is suspended, you will be unable to program a bolus or resume insulin delivery until the alarm is cleared.
If you experience this keypad condition, and want to resolve it immediately to bolus or clear the alarm, remove the battery cap from the pump and then place it back on.
PLEASE NOTE: You should have a fresh new AA battery available in case your pump prompts you to insert a new battery.
If you still experience issue with your keypad or pump buttons, you should contact the product support team.
