Turning On the Computer
After you set up your system, you’re ready to turn on the power.
But first, read the following safety rules to avoid accidentally
damaging your computer or injuring yourself:
Do not dismantle any part of the computer. Only remove
the cover to install or remove optional devices or change
jumper settings. If there is a hardware problem you cannot
solve after reading the information on troubleshooting in
Appendix A, check with your Epson dealer.
Always turn off the power, disconnect the computer’s
power cord, and wait five seconds before you remove the
computer’s cover.
Do not unplug cables from the computer when the power
is on.
