Installation/Support Tips

Power

The computer has an input voltage selection switch on the back panel to select between 115V, for USA and Canadian use, and 230V, for use in other countries.

Mouse and Keyboard

When connecting the mouse and keyboard to the computer, be careful to plug them into the proper ports. Although the ports are physically identical, they are not interchangeable, and damage may occur to the main system board if you plug the connectors into the wrong ports

Installing Diskette Drives

Make sure that the drive type has been correctly selected in the SETUP program.
