Under most conditions, if a product fails on another system, it is usually defective. However, with wireless products, this is not always the case. Other environmental variables will affect the performance of wireless devices.  These variables include battery life, interference, failure to connect (synchronize) the emitter to the receiver correctly, inserting the batteries incorrectly, etc.

When you are testing a wireless device for failure, it is important that you test with a fresh set of batteries. After inserting the batteries according to the instructions, you may need re-synchronize the emitter wireless mouse to the receiver.  To do this, press the "Connect" button on the receiver (small black button) and then press the "reset" button on the bottom of the mouse.  Move the wireless device on the desktop to see if the cursor now moves on the screen.

If you are using the Labtec Mini Wireless Optical M/N: M-RAW104, it ships with a mini dongle receiver that is paired with the mouse at the factory.  Therefore, you should not need to be synchronize it.

If the Labtec Wireless Device still does not function, please check to be sure the device detected correctly.

When testing a wireless device, it is important to note that performance can be affected by other electrical devices in the area of the receiver, such as Zip drives, monitors, metal desks or desks lined with metal. In these cases, try moving these devices at least 8 inches (21 cm) away from the wireless devices. You can also resolve interference issues by moving the mouse closer to the receiver. You may also want to experiment with different locations and positions for the mouse or laptop.
