Suggestions for Use and Care of the Monitor 100

Warning: Don’t leave your monitor exposed to direct sunlight. The heat can damage the case and even the electronics. Never put cups glasses or any vessel containing liquids on or beside the monitor devices. Remember that spilling a liquid into any electronic instrument can damage circuitry.

Here are some guidelines for using your Apple Monitor 100 and for keeping the monitor in good working order:

Position the computer and monitor as you prefer for your work. The computer line of Apple computers is large enough to place the Apple Color Monitor 100 directly on top of the computer’s case. Try and see if you like it there. If not, you can place the monitor to the side.

Important note: Remember that an active monitor generates signals that can interfere with a disk drive’s ability read a disk. If your system seems to have trouble reading disks, move the disk drive or drives away from the monitor.

You will probably want to use white-only display for text programs such as word processing, and reserve color for graphics programs. If you choose color mode while text is on the screen, the text will be white. Some software mixes color graphics and text in a single display. If the text in such a display contains color splotches, white-only mode will make the text easier to read.

To keep your eyes from tiring, avoid staring into the monitor for long periods of time without a break. Focus on a distant object from time to time. Whenever you look for any length of time into a light source such as a TV or a computer monitor, you may feel bleary-eyed. Though we have designed the screen to be comfortable for all users, you may still experience eye fatigue. If you feel your eyes tiring, just look away from the screen and focus on objects at varying distances awhile. By exercising your eye muscles in this way, you can avoid or relieve eye strain.

The Monitor 100 tough and can take some heavy knocks, but don’t abuse it!

The monitor’s vents are recessed to help prevent moisture from getting inside. But still, a spill could damage internal circuits. Before moving your monitor, be sure to unplug the video cable from it, and the power cord from the wall socket. When lifting and carrying the monitor, use the special finger recesses under the monitor sides.

The screen of the monitor is quite rugged. But still, to avoid scratching the screen, it’s a good idea not to lay the monitor face down. Like TV screens, monitor screens attract dust because of static electricity, and built-up dust makes for uncomfortable viewing. An occasional wipe with a dry, lint-free cloth will keep your monitor’s screen clean. Avoid smearing or smudging the screen with your fingers. The oil from your fingers will make dust adhere to the screen. The monitor’s screen has an etched anti-glare surface, which greatly reduces eye fatigue and makes reading easy, even when light reflects off its surface.

Remember, if you don’t take proper care of your monitor (if you abuse it, spill liquids on it, or drop foreign objects inside) or if you open it and try to modify it, your warranty will be void.


  • On Monitor 100, frequently used controls are easily accessible behind a protective door on the front of the monitor. Those buttons which were less frequently used were on the back.
  • AppleColor Monitor 100 is not compatible with the Apple IIGS. For the owners of the AppleColor Monitor 100 who were upgrading their IIe’s to the Apple IIGS, and wanted to avoid having to purchase a new monitor, there is a workaround: to make it compatible with the Apple IIGS, users had to connect a cable provided with the Monitor 100 to the Apple IIGS. This configuration made all colors available.
