Q: What should I do if the pointer is difficult to control or requires too much arm movement?
  1. Go to Control Panel, Mouse, and set the pointer speed slider to the middle
  2. Check the box for Enhance Pointer Precision
Q: What should I do if the pointer moves by itself?

A reflective surface may cause pointer drift. Put the Oyster Mouse on a non-reflective mouse pad, such as a fabric pad.

Q: What should I do if the pointer jumps to the screen edge?

The mouse is probably on a reflective surface. Put it on a completely non-reflective surface, such as a cotton mouse pad.

Q: What should I do if the pointer seems sluggish or moves randomly in response to mouse movement?

The mouse is probably on a reflective surface. Put it on a completely non-reflective surface, such as a cotton mouse pad. If the mouse tracks properly on white printer paper, it is working properly. The mouse surface must be completely flat for proper tracking.
