Opening the calculator helps, but not enough to make it the first act. I would save that as the last resort.
You can try cutting the end of the air tube to make it fit into the seam on the sides of the calculator. Just make two diagonal cuts so it forms a v. Jam it in the side and give it a blast, just making sure the can is level as David Smith mentioned. It will take several shots from either side to get it all. Stubborn bits might need help from a small strip of stiff paper slid in through the side seam. Don’t use anything sharp as the window material and LCD polarizer are soft material and scratch easily. Plastic coated paper (backing paper from double sided foam tape) works quite well for this as it slides in easily.
