INSTALLING/REPLACING BATTERIES

Your chess computer uses six C batteries (not included).  Fresh alkaline
batteries, such as Radio Shack Cat. No. 23-551, can provide up to 200
hours of playing time.

1.  If the computer is on, press and hold down GO/STOP until the display
    is blank to turn it off.

2.  Press and hold down the tab on the battery compartment cover in the
    direction of the arrow, then lift up the cover to remove it.

3.  If necessary, remove and discard the old batteries.

    CAUTION:  Dispose of batteries properly; do not bury or burn them.

    NOTE:  Saved game information is lost when you remove the batteries.

4.  Insert six C batteries as indicated by the polarity symbols (+ and -)
    inside the compartment.

    CAUTIONS:  Use only fresh batteries of the required size and type.

               Do not mix old and new batteries.

5.  Replace the cover.

    CAUTIONS:  Batteries installed incorrectly might leak and damage the
               computer.

               Never leave dead or weak batteries in the computer.

               If the computer will not be used for several days, and you
               do not want to save a game, remove the batteries.

If the computer does not function properly, replace the batteries.  If it
still does not function properly, you might need to reset the computer.
See "Resetting the Chess Computer", below.

Resetting The Chess Computer

If your computer does not work properly after you replace the batteries,
you might need to reset it. To reset the computer, insert a pointed object,
such as a straightened paper clip, into the ACL hole on the bottom of the
computer.  The computer beeps and the display shows ( [] ) and 0:00:00.

USING AN AC ADAPTER

With an optional AC adapter, such as Cat. No. 273-1455, you can operate
the computer from standard AC power.

NOTE:  To save game information, you must install batteries in the computer
       even if you are using an AC adapter.

CAUTIONS:  You must use an AC adapter that supplies 9 volts and delivers
           at least 150 milliamps. Its center tip must be set to negative,
           and its plug must correctly fit the 9VDC/150mA jack on the back
           of the computer.  The recommended adapter meets these
           specifications.  Using an adapter that does not meet these
           specifications could damage the computer or the adapter.

           Turn off the computer by pressing GO/STOP before you unplug the
           AC adapter or its barrel plug.

           Unplug the AC adapter from the AC outlet before you unplug its
           barrel plug from the computer.

Follow these steps to use an AC adapter.

1.  If the computer is on, press and hold down GO/STOP until the display
    is blank to turn it off.

2.  Insert the AC adapter's barrel plug into the 9VDC/150mA jack on the
    back of the computer.

3.  Plug the AC adapter into a standard AC outlet.
