How to Add Memory and an AirPort Card to the iMac G3 Slot-Loading DV+ 450 Hz?

Before installing:

  • Shut down the computer.
  • Unplug all cables, except the power cord.
  • Place the computer face down on a soft cloth.

Now proceed as follows:

  1. Open the access door using a coin to turn the latch.
  2. Touch the metal shield inside the recessed latch area.
  3. Unplug the power cord.
  4. Touch the metal shield before you touch any parts inside the computer. Don’t walk around the room until you’ve finished installing memory or an AirPort Card.
  5. To install memory, insert a memory module into one of the two lower slots. Be sure to align the notches on the
    module with the small notches inside the slot.
  6. To install an AirPort Card, detach the antenna from the guide rail, then remove the protective plastic cap. Warning: You must have an AirPort-compatible iMac to install an AirPort Card. If you don’t see the guide rail, your iMac is not compatible with AirPort.
  7. Connect the antenna firmly to the AirPort Card and insert the card sideways into the slot. For instructions on using the AirPort software, look in the Help Center, available in the Help menu of your computer.
  8. Close the access door and use a coin to close the latch. Warning: Never turn your computer on unless all of its internal and external parts are in place.

How to Work Comfortable with Your iMac

The guidelines in this section can help you work more comfortably with your computer. For detailed information about ergonomics, see Apple’s Environmental Health and Safety Web site.

Using the Keyboard:

When you use the computer keyboard, your shoulders should be relaxed. Your upper arm and forearm should form an approximate right angle, with your wrist and hand in roughly a straight line.

You may have to raise your chair so your forearms and hands are at the proper angle to the keyboard. If this makes it impossible to rest your feet flat on the floor, you can use a footrest with adjustable height and tilt to make up for any gap between the floor and your feet. Or you may lower the desktop to eliminate the need for a footrest. Another option is to use a desk with a keyboard tray that is lower than the regular work surface.

Use a light touch when typing and keep your hands and fingers relaxed. Avoid rolling your thumbs under your palms.

Using the mouse:

Position the mouse at the same height as your keyboard. Allow adequate space to use the mouse comfortably.

Using the chair:

An adjustable chair that provides firm, comfortable support is best. Adjust the height of the chair so your thighs are horizontal and your feet flat on the floor. The back of the chair should support your lower back (lumbar region). Follow the manufacturer’s instructions for adjusting the backrest to fit your body properly.

Working with the computer:

Arrange the computer so the top of the screen is slightly below your eye level when you’re sitting at the keyboard. The best distance from your eyes to the screen is up to you, although most people seem to prefer 18 to 28 inches (45 to 70 cm). Position the computer to minimize glare and reflections on the screen from overhead lights and windows.

Warning: Don’t lift the computer using the flip-out foot. You could damage your computer. To move your computer, grab the handle on the top of the computer with one hand; with your other hand, hold the bottom of the computer. Also remember that electrical equipment may be hazardous if misused. Operation of this iMac must always be supervised by an adult. Do not allow children access to the interior of this product and do not permit them to handle any cables.
