It is possible that the reflectivity of the surface on which this
product is being used is not suitable for an optical mouse.
Use this product on a mouse pad that is designed for use with
optical mice.
When using this product on a metallic surface such as a steel
desk, radio wave outreach may be shortened. In such cases,
move the receiver unit closer to the mouse until mouse
operation stabilises.
It is possible that the receiver unit is not connected correctly to
the USB port. Disconnect the receiver unit from the USB port and
reconnect it.
The receiver unit and the mouse body are too far apart or there
is a possibility that the receiver unit is facing in a direction from
which it cannot receive radio signals. Adjust the position of the
receiver unit.

If you have installed drivers and settings utilities produced by the
original manufacturer for a previous mouse, uninstall them first.
This product may not operate correctly if a driver made by another
company is installed. See the instruction manual that was supplied
with your previous mouse for uninstall instructions.
It is possible that the driver is conflicting with another driver
such as that for a laptop touch pad. To use this product
