WARNING: HIGH VOLTAGE
Text or photographs marked by this symbol indicate that a potential hazard to your personal
safety exists from a high voltage source.
The AC/DC power supply board is a high voltage source with the unit under power, and remains
powered up whenever the system is plugged in, whether or not the system is turned on. Use
extreme caution when troubleshooting the system with the front bezel removed.
Disconnect power to the system before performing maintenan• ce.
Don’t work alone. In the even• t of an electrical shock it is important to have another
individual present who can provide assistance.
Keep one hand in your pocket when working on any iMac G5 (iSight) that is plugged in. •
This will help ensure that your body does not provide a path to ground in the event that
you accidentally make contact with the line voltage.
Don’t wear jewelry, watches, necklaces, or other metallic articles that could present a risk •
if they accidentally make contact with the power supply circuitry.
