Congratulations on your purchase
of Excalibur Electronics’ innovative LCD Chess! You’ve purchased
both your own personal chess trainer and a partner who’s always ready
for a game—and who can improve
as you do!
Install the Batteries
Using a small Phillips screwdriver,
remove the battery-compartment
panel screw on the back of LCD
Chess. Then remove the panel by
pulling gently from the top. Install
three fresh, alkaline AAA batteries,
making sure to follow the diagram
in each battery slot so that the
polarity (+ or -)
of the batteries is
Excalibur’s LCD Chess is designed so
that it can be held comfortably and
used with one hand.
correct.
Replace the battery compartment
panel by first fitting the two bottom
tabs into their receptacles. When
replacing the screw, secure it gently.
Do not force or over-tighten it.
Play a Game Right Away After
you have installed the batteries, the
display will show the chess board
with all the pieces on their starting
squares. The LCD will also show
"
01 CHESS." This indicates you
are at the first move of the game
and ready to play chess. If it doesn't

MODE and then NEW GAME.
Unless you instruct it otherwise,
LCD Chess gives you the White
pieces—the ones at the bottom of
the board. White always moves
first. (For the complete rules of
chess, see the
brochure included in this package.)
You’re ready to play!
Make your first move with your
choice of two methods. In both
methods, it’s very important to
understand that making a move is
made up of two parts, choosing a
from square and a to square.

Let’s Play Chess
Moving with the
DIRECTION rocker
The first method makes the most of
the central, DIRECTION rocker.
The eight- direction rocker button
may be difficult to use at first. It is
different from some video game
controllers because it allows diagonal movement.
For up, down, left and right movements, it helps if you push the button straight out away from the center of the rocker. Do not press in the
center of the rocker, because you
may cause a diagonal movement to
occur.
1. Push the DIRECTION rocker in
any direction and the White
queen’s rook (the piece on the bottom, left) will flash on and off. The
top of the display will read "
." Then move the circular
FROM
rocker button—to the right, left, or
diagonally—until the piece or
pawn you want to move flashes on
and off.
2. Push the OPTIONS/MOVE button immediately above the circular
DIRECTION rocker.
3. Push the DIRECTION rocker to
move the piece to the square you
want. You’ll see your piece flashing
on possible
it—at the same time it continues to
flash on its
to squares as you move
from square.

Note: Press MODE twice and it
will act as a “clear” key. For
example, use it to stop a square
from flashing in #3 above.
4. Push the OPTIONS/MOVE button again to finalize your move.
The second method of moving uses
the DIRECTION rocker in only
one step (2).
Moving with
the NEXT PIECE
and LAST PIECE KEYS
1. Select the piece you want to
move by pressing the NEXT
PIECE or LAST PIECE key until
the piece you want to move flashes.
2. Then use the center DIRECTION rocker button to move the
flashing piece where you want it.
3. Finally, press the MOVE key to
register your move.
After you make your move, LCD
Chess will reply with its move
automatically. You’ll see the piece
flash on its

of the move number and the
elapsed time for each move.
Playing the Black Pieces
When you want to play the Black
pieces (to let LCD Chess move
first) press the MOVE button twice
before you make your first move as
from square and move
to square. Throughout the

Function Keys" below.) You’ll see
the White and Black pieces switch

Levels of Play
Generally, the higher the level you
select, the better your LCD Chess

will play, and the longer it will
think during its moves. With over
1,000 level setting combinations
(incorporating options such as
RANDOM, INFO, HELP and the train-
ing modes) to choose from, you can
learn and grow with this chess
computer!
The first four levels (1, 2, 3 and 4)
are beginner levels and take
approximately 4, 8, 12 and 16 seconds per move, respectively. Level
5 is a fixed 1-ply (one-half move)
search. Levels 6 through 72 take
about 1 second per level number, so
level 6 will average about 6 seconds per move. The amount of time
taken will vary depending on the
position, the stage of the game, and
whether or not the FAST level
option is on. (See “Options,” pages
4 & 5.)
Level 73 is an infinite level. LCD
Chess will take as long to move as
you want it to, or until it finds a
mate position in its search. Level
!”
73 is good for problem solving
(like the MATE problems available
under OPTIONS), or it can be used
to play against. When you are tired
of waiting, press the MOVE key
while the computer is thinking, and
the computer will stop thinking and
play the best move it’s found so far.
