3830 SL  (250-3573)           Keyboard Functions        Faxback Doc. # 1234

Your computer has 84 keys that emulate the functions of a standard 101-key
keyboard.  The keyboard consists of four sections--typewriter keys, control
keys, arrow (cursor) keys, and special keys.  The functions of most of
these keys depend on the program you use.

Using Key Combinations:

You can also control computer functions by using key combinations.  To use
a key combination, press and hold down the first key.  Then, press the
other key(s) in the sequence indicated.  For example, pressing and holding
down FN and then pressing F7 turns off the computer LCD and backlight.
Pressing any key turns the LCD and backlight back on.

Special Key Combinations:

The following key combinations have special significance to the computer
processor or screen.

FN + F1 (Color)--lets you select from various shades of gray when Max
Contrast is disabled in Setup383.  Choose the setting that works best with
the software you are using.

Note: The setting you select using this key combination updates the
      computer CMOS.

FN + F2 (Video)--switches between the built-in screen, an external monitor,
or both.

Note: This key combination might not operate with some software.

If you need to interrupt your work, you can put one or more computer
functions in a standby mode to conserve battery power.

FN + F3 (Speed)--Switches the speed of the processor between fast (25 MHz)
and slow (12.5 MHz).  At the fast setting, the POWER indicator is green.
At the slow setting, the indicator is orange.

FN + F4 (Disk)--Turns off the hard disk drive motor.  The next time the
computer accesses the drive, it automatically turns back on.

FN + F5 (Spkr)--Turns off the internal speaker.  Press FN + F5 again to
turn the speaker back on.

FN + F6 (Bright)--Changes the backlight brightness setting.  Press and hold
down FN.  Then, repeatedly press F6 to step through the three stages of
backlight brightness (low, medium, and high).

FN + F7 (Display)--Turns off the LCD and its backlight.  Press any key to
turn the LCD and backlight back on.

FN + F8 (Serial)--Disables the serial port and modem.  Press FN + F8 again
to enable the port and modem.

FN + F10 (Standby)--Turns off the hard disk drive motor, the LCD and its
backlight, and slows the CPU speed.  Pressing any key turns the LCD and
backlight back on.  As you continue your work, the hard disk drive turns on
the next time you need it and the CPU returns to the normal speed.

Typewriter Keys:

The typewriter keys include the letters and numbers on the keyboard and are
similar to the keys on a standard typewriter.

Control Keys:

You use some control keys to move to a different place in a document.  For
example, pressing PGUP moves the document to the previous page.  Other
control keys move the cursor or delete or insert text at the current cursor
position.  For example, pressing the tab key moves the cursor to the next
tab position.

Arrow (Cursor) Keys:

The cursor keys move the cursor up, down, to the left, and to the right.

Special Keys:

The special keys control the operation of the computer of programs you use.
For example, pressing prtsc/sysrq sends to the printer the information
currently on the screen.

Numeric Keypad:

The numeric keypad on the keyboard (printed in red) is similar to a
calculator keypad.  Press FN + KEYPAD to activate the numeric keypad area.
The KEYPAD indicator lights.  If the NUMLK indicator is not on, press
NUMLK.  The values of the keys on the numeric keypad area are 0-9, decimal
(.), plus (+), minus (-), multiplication (*), and division (/).  Press FN +
KEYPAD again to return to the normal keyboard functions.

Note: To temporarily activate the numeric keypad area, hold down FN while
      you press the desired keys.

You can also use the numeric keypad are to emulate other keypad functions
of a 101-key keyboard.  If you turn off the NUMLK indicator while the
keypad is active, the numeric keypad area provides alternate cursor keys,
HOME, END, PGUP, PGDN, INS, and DEL.  Some programs require you to use
these alternate keys instead of the separately provided keys.  See below.
Press NUMLK to switch between numeric key entry and the alternate
functions.
