To maintain good communication, operate the wireless mouse within the distance limitations of mouse: approximately 33 feet (10 m) from your 
computer.

Avoid using any wireless devices that exchange radio signals on the 2.4 GHz band near your wireless mouse. These devices may create radio 

interference, causing the mouse to stop working properly.

Use surfaces such as plain paper, card stock, or fabric that have minimal repetitive patterns.

Avoid using the wireless mouse on surfaces such as mirrors, smooth glass, or magazines that have half- tone printing.

Do not place metal furniture or objects near your computer or wireless mouse, as this may create radio interference, causing the mouse to stop working 
properly.

Be sure to use an alkaline battery. Using an incompatible battery can damage the wireless mouse.
