Using this Beta Blue sticker is easy. Just peel it off and stick it on your Medtronic MiniMed 770G or 780G insulin pump. Make sure the surface of the pump is clean before you apply the sticker. When you're done, smooth out any air bubbles. As for maintenance, you can gently wipe it with a soft, dry cloth. Avoid using harsh chemicals or sharp objects on it. Also, keep in mind that the colors and designs may vary slightly. And don't forget, Peelz products are sold separately from the devices.
