Incorrect Insertion Method
After you insert the microSD memory card into the slot, if you feel resistance when closing the cover, do not push
down or try to force the cover to close.

When the cover is open make sure it is pushed back toward the hinge. The cover should lay down flat and close
easily with no resistance. Once the cover is closed, slide it into the lock position away from the hinge.
