Pull up on the suction cup with strong, steady force to create a gap between the cover
and the frame. Slide the opening pick back and forth along the right edge to slice
through the adhesive.
Leave the pick inserted near the bottom of the right edge to prevent the adhesive
from resealing.
As the back cover can be damaged by excessive force, be careful not to damage
the back cover.
If you have trouble creating a gap, heat the microwaveable heating bag
additionally, and apply it on the back cover to further soften the adhesive. When
reheating, it should be heated no longer than 30 seconds.
