IBM B50 - Manual (Page 45)

With the mouse buttons, you can perform functions such as selecting and
deselecting options, extending your selection, or choosing a command. The precise
function of your mouse depends on the software you are using.
The mouse has a cable that plugs into a connector at the rear of the server.
Handling the Mouse Correctly
For best operation, handle the mouse with care. Incorrect handling can damage the
mouse.
Do not:
Operate the mouse on cloth, unfinished wood, newspaper, or carpet.
Drop or hit the mouse.
Carry the mouse by holding onto the cable.
Expose the mouse to extreme temperatures or direct sunlight.
Place the mouse in liquid spills.
Caring for the Mouse
The operating surface for the mouse should be smooth, clean, and flat. For
example, you can operate the mouse on the following surfaces:
Finished wood
Glass
Enamel
Plastic
Paper (except newspaper)
Metal
Rough surfaces collect contaminants that can be transferred to the interior of the
mouse by the ball. Rough surfaces can also cause the pads located on the bottom
of the mouse to prematurely wear. A deeply pitted surface could cause erratic
operation of the mouse. The surface you use should be free from spills, dirt, dust,
lint, wax, eraser dust, and other foreign matter.
To care for the mouse:
Inspect the work surface for spills or other contaminants.
Dust the work surface.
If you are using a paper pad, inspect it for wear and replace it if necessary.
