VI. ILLEGAL MOVES
If you try to make an illegal or an impossible move, you will hear an error tone indicating that your move is not legal and that the computer will not
accept the move.
If you try to make an illegal move or if you try to move a chess-man that belongs to your opponent, you will also hear the error sound.
You can continue to play the game by making another move instead.
If you hear the error signal, and the computer shows you a square by illuminating its coordinates, you must press the square indicated before continuing
the game.
VII. CHECK, CHECKMATE AND STALEMATE
When the computer announces check, it transmits a triumphant beep and lights up the "CHECK" indicator.
In the case of check and checkmate the computer plays a short tune and light ups the CHECK and DRAW/MATE indicators. If the computer is
checkmate, the indicators light up permanently; if you are checkmate, the indicators flash on and off.
If stalemate occurs, the DRAW/MATE light will illuminate which indicates a draw.
If the same position is repeated three times in a row, or if moves have been made without a capture or movement of pawns, this will also cause the
DRAW/MATE indicator to light up; you may continue the game if you want to.
VIII. OFF/SAVE
When a game is finished, you can press the NEW GAME to start a new game or switch off the computer by pressing the SAVE/OFF button. In fact, the
computer is not switched off completely. It saves the current position in its memory and only requires minimum power to do so. In other words, you
can stop playing in the middle of a game, switch off the computer and then switch it back on later in order to continue your game. This also means
that you must press the NEW GAME button after switching on the computer if you want to start a new game.
IX. SOUND AND LIGHT EFFECTS
If you prefer to play in silence, briefly press the SOUND/COLOUR button. This will switch off the sound effects of the computer. To re-activate the sound,
press the SOUND/COLOUR button once again. The sound is also switched on again when you press the NEW GAME button.
