Use a flathead screwdriver to remove the screw from the device.

The size of the driver will depend on the size of the screw, but use the largest size that will fit in your cut.

If you cannot fit a screwdriver into the cut, use the rotary tool to make the cut larger. Make only small cuts; if you cut off too much of the screw, a screwdriver will not catch and you will not be able to twist the screw.

Wear eye protection and give your device a few good blasts of compressed air before reassembling it. The rotary tool can scatter loose metal shavings around the device, creating the potential for an electrical short if not blown clear.
