Chapter 3
Operating DCU 220
This chapter provides information about the use of DCU 220.
If you are new to computers, reading this chapter will help you learn the operating basics. If
you are already a computer user, you may choose to read only the parts containing
information unique to DCU 220.
CAUTION:
Do not expose your skin to DCU 220 when operating it in a very hot or cold
environment.
DCU 220 can get uncomfortably warm when you use it in high temperatures. As a
safety precaution in such a circumstance, do not place DCU 220 on your lap or touch
it with your bare hands for extended periods of time. Prolonged body contact can
cause discomfort and potentially a burn.
Using the keyboard
Your keyboard has all the standard functions of a full-sized computer keyboard plus an Fn
key added for specific functions.
The standard functions of the keyboard can be further divided into four major categories:
Typewriter keys
Cursor-control keys
Numeric keys
Function keys
Typewriter keys
Typewriter keys are similar to the keys on a typewriter. Several keys are added such as the
Ctrl, Alt, Esc, and lock keys for special purposes.
The Control (Ctrl) / Alternate (Alt) key is normally used in combination with other keys for
program-specific functions. The Escape (Esc) key is usually used for stopping a process.
Examples are exiting a program and canceling a command. The function depends on the
program you are using.

Cursor-Control Keys
Cursor-control keys are generally used for moving and editing purposes.
Note:The word “cursor” refers to the indicator on the screen that lets you know exactly
where on your screen anything you type will appear. It can take the form of a vertical or
horizontal line, a block, or one of many other shapes.

Numeric Keypad
A 15-key numeric keypad is embedded in the typewriter keys as shown next:
Numeric keys facilitate entering of numbers and calculations. When Num Lock is on, the
numeric keys are activated; meaning you can use these keys to enter numerals.
NOTE:
When the numeric keypad is activated and you need to type the English letter in the
keypad area, you can turn Num Lock off or you can press Fn and then the letter
without turning Num Lock off.
Some software may not be able to use the numeric keypad on DCU 220. If so, use the
numeric keypad on an external keyboard instead.
Function keys
On the top row of the keys are the function keys: F1 to F12. Function keys are
multi-purpose keys that perform functions defined by individual programs.
Fn key
The Fn key, at the lower left corner of the keyboard, is used with another key to perform the
alternative function of a key. To perform a desired function, first press and hold Fn, then
press the other key.
