The display will show _ to symbolize an empty chessboard.
Press ENTER once more to confirm that you do want to clear the
board. Then add pieces as described previously. If you decide not
to clear the board, press CLEAR to cancel. This feature can be
handy when you want to set up a position with only a few pieces,
where it would be much easier to start out with an empty board!
• Once you have changed the board position as described
above, make sure the color indicator in the display is showing the
correct color of the side to move. Change the color, if necessary, by
pressing BLACK/> or WHITE/<.
• To exit Position Mode, press CLEAR. You will return to normal

Note that any legal position can be set up using the above proce-
dures. The computer will not permit you to set up an illegal position,
such as one where there are more than the prescribed number of
pieces for a normal game, or one where a King is in check and is not to
move. In such cases, the computer will simply beep when you press
CLEAR, and you will not be allowed to exit Position Mode. Check the
position using the PIECE SYMBOL KEYS, if necessary, and correct the
position (by adding a piece, removing a piece, or moving an incorrectly
placed piece). Then press CLEAR to exit Position Mode.

7.1 The ACL Function
Computers sometimes “lock up” due to static discharge or various
other electrical disturbances. If this should happen, take out the batter-
ies and use a pin or another sharp object to press into the hole marked
ACL in the base of the unit for at least one second. This resets the
computer.
