CHAPTER 6: Troubleshooting
The display is blank.
Check the batteries to see that they are
installed correctly and that they are not
too weak. Otherwise, insert a safety pin
(or another sharp, thin object such as a
pen) into the ACL hole (reset) located on
the lower back of the computer.
Computer gives an improper response.
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
m ov e s were performed corr e c t ly, for
example, and remember you cannot move
and remain in check. You also may not
castle through check.
LCD messages are dim or faded, your
computer functions undependably or
displays impossible moves.
Install new batteries immediately. See
Section 1 above.
Computers can sometimes “lock up”
due to static discharge or other elec-
trical disturbances. If this should
happen,use a slim, pointed object to
press the button marked “ACL” on
the bottom of the unit.
For best results, always use alkaline batteries. Be sure to check their
expiration date because fresh batteries will ensure uninterrupted usage
and enjoyment of the product. Remove the batteries if the product will
not be used for an extended period. If the product does not perform
as expected, check for proper battery charge and correct battery
installation, or try a fresh set of batteries.
