Epson 7500 - Manual (Page 22)

You can change the angle of the keyboard by adjusting the legs
on the bottom. Turn it over and flip each leg upward until it
locks into place. It is important to select the best angle so you
will prevent wrist fatigue. (You may even want to purchase a
wrist pad-sold at computer stores-for further comfort.)
To lower the keyboard, press each leg back into its slot.

Connecting the Mouse
Your computer has an auxiliary port for an IBM®
compatible mouse that uses a round, miniature DIN (6-pin)
connector. If your mouse has this type of connector, you can
connect it to the computer’s built-in port.
Note
If your mouse requires a different interface port, you can’
connect it to the built-in serial port or install an option card
that provides the interface. When your system loads the
mouse driver, it will properly identify the location of your
mouse.
