GB-12 Troubleshooting Symptom Mouse Not Detected If lens is not illuminated red: If green light on receiver does not blink: Cursor Does Not Move At All Probable Cause Computer ports are improperly set up (for example, are disabled). Conflicts among other devices connected. Installed on an incompatible operating system. No power. USB receiver not recognized. Mouse not detected. Optical sensor may be blocked by dust, dirt or crumbs. Mouse is on an incompatible surface. Solution Check with your computer system dealer or manufacturer if you need help. Resolve any conflicts among devices connected to your computer. Compatible operating systems for the 3M Ergonomic Mouse EM550 are listed on page 2. Make sure the power switch is ON.

See "Mouse Not Detected" above. Blow or brush the obstruction away with a soft cloth. However, do not insert hard objects through the opening. DO NOT use your mouse on a transparent surface like glass or a reflective surface like a mirror; on a rough or porous surface that is not smooth; or on a surface with complex graphic and color patterns. Difficult To Control Fine Cursor Motion You are using larger muscle groups to move the mouse. It can take up to a week to train new muscle groups to mouse and gain fine cursor control. Slow down the pointer speed or acceleration in your operating system's mouse utility software.
