User's Manual

When the computer is running at 6 MHz, the LED power light is red. At

8 MHz, the LED is orange, and at 10 MHz, the LED is green.

After you change the speed, you need to reset the computer by pressing

the RESET button to make the new speed take effect. See “Resetting the

Computer” below.

WARNING: Do not change the speed while you are running a program;

if you do, the computer hangs up. Complete your current

operation, exit the program, and then change the speed

and press

RESET.

Resetting the Computer

You can reset the computer to load a different operating system or to

reload the current operating system. For example, if an error occurs and the

computer does not respond to your keyboard commands, you can reset the

computer and try the same operation again. However, resetting erases all

data in the computer’s temporary memory (RAM), so reset your computer

only as a last resort.

In MS-DOS, you can hold down Ctrl and press C to stop a program’s

operation and return to the MS-DOS command prompt. If an error occurs,

try this method before you reset the computer.

WARNING: Do not reset the computer to exit a program unless you

have to. Some application programs classify and store new

data whenever you exit the program properly. If you reset

the computer while such a program is running, you may

lose data.

There are three ways to reset. Because each is more powerful than the

last, try them in the order listed here:

If you are using MS-DOS, hold d

own

Ctrl

and

Alt

and press the

Del

key on the numeric keypad at the right of the keyboard. The screen goes

blank for a moment and then MS-DOS reloads. (MS-DOS must either

be on the diskette or be autobootable from the hard disk.) If this does

not correct the problem, try the second method.

Press the RESET button on the front panel. This method works even

when the keyboard does not respond to your commands. If this does not

correct the problem, try the third method.
