Exercises: 3.3 and 5.1

Exercise 3.3: Degaussing a CRT Monitor

**You can only degauss a CRT monitor** If you want to reduce the magnetic field of an object. You cant reduce the magnetic field entirely, so you can only attempt to reduce it some.** There may be times that you need to degauss your monitor. For instance, if you have a glare on the monitor you can degauss the magnetic field.

The steps to degauss the monitor are fairly simple. Once the monitor is powered on, the steps are as followed:
1. Press the menu button in front of the Monitor. There are 4 buttons in a circle and then one by itself, on the far right. Make sure to press that button.

You will notice a screen shot that displays a menu of results. The monitor will automatically detect the type of signal that it being received from the graphics adapter. It detects the refresh rate.

2. Select the Extra Controls sub menu by using the up and down arrow keys.
3. Once you press the menu button, the degauss option is already selected. If your CRT needs degaussing, you will hear a distinctive noise and you will also see the image distorting.

The next exercise deals with Printers. Exercise 5.1 covers: Identifying the Parts of a Bubble-Jet Printer.

This is a very helpful tool but a technician should be able to know the difference between the different types of printers. Not only that, once the type is identified, individual parts can then be pointed out within the different types of printers. In this example, we are identifying parts in an inkjet, also called a Bubble-Jet printer.
