Using a different cartridge type than what is configured in the insulin pen can lead to both Hypoglycemia and Hyperglycemia.

When the plunger resets and the "Please insert a new cartridge" screen flashes (for up to 5 minutes), insert the new insulin cartridge you prepared into the cartridge holder.

   • Note that when attaching the needle, injection fluid may flow out due to cartridge compression.

   • Refer to "Step 1. Pen Needle Attachment" in Chapter 3.1 of this user manual for instructions on attaching the pen needle

2. When the "Air Removal" screen is displayed, hold the P8 with the attached needle pointing upward and tap the cartridge holder with your finger or other objects to lift any air bubbles in the cartridge as much as possible.
