user's guide
Problem
The optical sensor uses the
pattern of the surface to
track the position of the
cursor. Reflective surfaces,
grooved surfaces, glass, or
other see-through surfaces
inhibit the ability of the
sensor to track the cursor.
Mouse sensor is dirty.
The wireless mouse moves
the cursor more quickly than
a standard mouse.
Problem
All memory in the PC is
being used by open
programs, and memory is
needed for a desired task.
Problem
Cables are caught in the
cable tunnel.
Solution
Place the mouse on a mousepad or white sheet of paper.
Wipe the light sensor lens on the bottom of the mouse with
a lint-free cloth (not paper).
Adjust the mouse speed. See page 21.

Close all open programs, and then try desired task again.
