installed correctly and that they are not
too weak. Otherwise, insert a safety pin

pen) into the ACL hole (reset) located on
the lower back of the computer.

Use the VERIFY function to check
whether a mistake was made in moving
the pieces. Check also that the to square
has been properly pressed for your move.
Finally, check that the move you wish to
make is legal. Check that en passant

happen,use a slim, pointed object to
press the button marked “ACL” on
the bottom of the unit.
