What should I do if the mouse pointer jumps or moves slowly?

• If the mouse pointer does not move as intended, make sure the mouse is placed on a lusterless surface (printing paper, etc.), or a mouse pad for an optical mouse, etc.
  The mouse pointer may not move as intended on the following surfaces:

• Light-transmissive material (glass, etc.)

• Light reflecting material (glossy vinyl, mirror, etc.)

• Consistent pattern surface, such as a half tone print (photograph in magazine or newspaper, etc.)

• Stripe or other pattern with sharp contrast

• Gloss finish mouse pad or desk, etc.
