VERIFYING PIECE POSITIONS

You can use the piece symbol keys to verify the location of any piece on
the chess board during your turn.  Each time you press a piece symbol key,
the rank/file board lights indicate the piece's location.

NOTE:  You can use the piece symbol keys only during your turn.

For example, if the white queen is on square D1 and you want to verify its
location, press the queen's symbol key once while [black] is lit. The rank/
file board lights show square D1.  Or, if the black queen is on square F6
and you want to verify its location, press the queen's piece symbol key,
then press [black]/[white] until [white] is lit. The rank/file board lights
flash to show square F6.

To locate all pieces of the same color and type, repeatedly press [black]/
[white] until the indicator lights for the piece's color, then repeatedly
press the piece's symbol key.  If there is more then one of the same color
piece of that type on the board, the rank/file board lights show the
location of a like piece each time you press the piece's symbol key. If you
press [black]/[white] then repeatedly press the piece's symbol key, the
rank/file board lights show the location of a like piece of the other
color's pieces.

PROBLEM SETUPS

You can use the setup mode:

  To erase, re-enter, or relocate pieces any time before or during a game.

  To set up problems or puzzles for the computer to solve.

NOTE:  If you have already started a game, you must press SET UP during
       your turn to enter the setup mode.

       Before using this mode to create your own positions, familiarize
       yourself with this procedure by setting up the board positions
       described in the following examples.
