I would try:
a) Replacing the battery.
b) Positioning the Transmitter in an unobstructed spot, away from other electronic devices that may be interfering with it. Keep it close though.
c) Go the the Mfr. website and look for a newer or more appropriate driver.
d) Is there a "reset" button on the mouse and transmitter? Often it's just a little
hole that you push a paperclip through for a couple seconds. Try that too.
If these steps fail, try plying it with chedder.
