Removing the Feet/Feet wobble (Smart Typewriter)
If you use a very small, flat object, like a screwdriver, you can very carefully pull the feet out of the bottom of your Smart Typewriter. It is a friction fit, meaning they are not attached to anything or screwed in. However, they can be damaged easily, and if that happens, they may not fit back in properly.
If your device wobbles, check to see that the feet are pushed into the recesses of the device. Press down on the device on the high corners while the device is on a flat surface.
