HP Compaq Presario,Presario 5116 Quick Start Manual page 44

Your computer comes with
a cordless scroll mouse,
which you will need to set
up before use. The
cordless mouse is not
connected directly to the
PC, so there is no
struggling with mouse
cords that catch, tangle,
and limit your movement.
Important safety information!
Before using your mouse,
please read the Comfort
Guidelines that are on
Logitech's Internet site:
www.logitech.com.
1. Remove the battery compartment cover.
2. Insert batteries. Follow the diagram inside the battery
compartment.
3. Replace cover.
The receiver for your cordless mouse may be connected to a
USB or a parallel port. Before installing your mouse, turn off
your computer. To connect the receiver to a USB port, first
remove the PS/2 adapter.
Press the connect button on the receiver, then press the Connect
button under the mouse.
