CONNECTING TO POWER

INSTALLING BATTERIES

You can power the computer from six C batteries.  We recommend alkaline
batteries, such as Radio Shack Cat. No. 23-551.

Follow these steps to install batteries.

CAUTION:  When you replace batteries, install the inside row of batteries
          within 10 seconds after removing the old ones.  Otherwise, you
          lose the information for the current game.

1.  If you are replacing batteries, press STOP to turn off the computer.

2.  Remove the battery compartment cover by pushing the latch in the
    diretion of the arrow.

3.  Install the batteries, as indicated by the diagrams inside the
    compartment.

4.  Replace the cover.

5.  The first time you install batteries, press STOP to turn it off.  Then,
    press and hold down PLAY and press GO.  This initializes the computer.

The indicators alternately light as the computer runs a brief self-test. 
Then, the WHITE and MODE indicators light.

A fresh set of alkaline batteries provides about 100 hours of playing time.
Replace the batteries when the display becomes dim or the sound becomes
weak.

USING AN AC ADAPTER

To conserve battery power, you can power the computer from a standard AC
outlet.  This requires an optional adapter, such as Cat. No. 273-1455.

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 computer's 9VDC/150 mA jack. 
           Using an adapter that does not meet these specifications could
           seriously damage the computer or the adapter.

           We recommend you install the batteries even if you plan to power
           the computer with an AC adapter.  This protects the information
           stores in the computer's memory in case the AC power fails or
           you unplug the the adapter.  See "Installing Batteries".

Follow these steps to use AC power.

1.  Press STOP to turn off the computer.

2.  Plug the adapter's barrel plug into the computerr's 9VDC/150 mA jack.

3.  Plug the adapter's other end into a standard AC outlet.

CAUTION:  Press STOP to turn off the computer  before you unplug the
          adapter from the outlet or computer.  This helps protect the
          information stored in memory.
