Epson I+ 9Turning On the Computer, Safety rules

9Turning On the Computer

After you set up your system, you’re ready to turn on the power and start using your Equity I+. But before you do turn it on, read the following safety rules.

Safety rules

1.Never turn the computer on or off with a disk drive protector sheet in the disk drive.

2.Do not attempt to dismantle any part of the computer. Only remove the top cover to install and remove option cards. If there is a hardware problem you cannot solve after reading Chapter 4 on troubleshooting, or if you want to install an optional 8087 math coprocessor, consult your Epson dealer.

3.To install or remove option cards, always turn off the power, disconnect the main power cord, and wait for a few minutes before removing the cover from the computer.

4.Do not unplug cables from the computer while the power switch is on.

5.Never turn off or reset the computer when one of the drive lamps is on. This can destroy data stored on a disk or make a whole disk unusable.

6.Always wait at least five seconds after you switch the power off before switching it on again. Turning it off and on rapidly can damage the computer’s circuitry.

7.Never leave a beverage on top of, or next to, your system or any of its components. Spilled liquid damages the circuitry of your components.

Now you are ready to turn on your system. It’s a good idea to turn on the monitor and any peripheral devices before you turn on the main unit.

First, make sure the power cord is plugged into the power inlet on the back panel of the main unit. Then plug the power cord into a three-prong, 120-volt, grounded electrical outlet. Turn on the monitor so you can see the messages that appear as your computer starts up. If you have a printer or other peripheral device, turn it on next.
