INSTALLING BATTERIES

Your chess computer uses six C batteries (not included).  Fresh alkaline
batteries, such as RadioShack 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.  While pressing and holding down the tab on the battery compartment
    cover in the direction of the arrow, lift up the cover to remove it.

3.  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, different types of
               batteries (standard, alkaline, or rechargeable), or
               rechargeable batteries of different capacities.

4.  Replace the cover.

CAUTIONS:  Never leave dead or weak batteries in the computer.

           Batteries installed incorrectly might leak and damage the
           computer.

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

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

Note:  Saved game information is lost when you 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 (all clear) hole on the bottom of the computer.
The computer beeps and the display shows [] and 0:00:00.

Note:  Resetting the chess computer erases any game you stored.

USING AN AC ADAPTER

With an optional AC adapter, such as Cat. No. 273-1662, you can operate
the computer from standard AC power.

IMPORTANT:  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 100 milliamps.  Its center tip must be set to negative
           and its plug must correctly fit the 9V 100 mA 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.  Set the AC adapter's 5.5 mm outer diameter/2.1 mm inner diameter
    barrel plug to negative.

3.  Insert the barrel plug into the 9V 100 mA jack on the back of the
    computer.

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