ATTACHING THE TRANSMITTER'S ANTENNA

To ensure consistent operation and maximum operating range, tightly screw
the antenna's threaded end into the transmitter's antenna connector.

INSTALLING THE VEHICLE'S ANTENNA TUBE

The antenna tube holds up the antenna wire for the best reception and
range.  Route the antenna wire's loose end through the tube.  Then insert
the tube securely into the vehicle's tube holder.

INSTALLING BATTERIES

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

           Never leave dead or weak batteries in the transmitter or the
           vehicle.

           If you do not plan to use the vehicle for a week or more,
           remove and store the batteries.

           Do not mix old and new batteries.

           Dispose of batteries properly.  Do not bury or burn them.

In the Transmitter

You need six AA batteries (Cat. No. 23-552 or 23-652)to power the
transmitter.

1.  Set the transmitter's ON/OFF switch to OFF.

2.  Slide the battery compartment cover off in the direction of the arrow.

3.  Install six fresh AA batteries, as indicated by the polarity symbols
    (+ and -) marked inside the compartment.

4.  Replace the cover so it snaps into place.

In the Vehicle

You need four AA batteries (Cat. No. 23-552 or 23-652) in the vehicle, so
it can receive signals.

1.  Set the vehicle's ON/OFF switch to OFF.

2.  Lift the tab on the battery compartment lid (located on the bottom of
    the vehicle) and slide the lid back.  Then swing the lid back on its
    hinge.

3.  Install four fresh AA batteries, as indicated by the polarity symbols
    (+ and -) marked inside the compartment.

4.  Replace the cover so it snaps into place.

Note:  If the vehicle does not operate properly or if its range decreases,
       replace all four batteries.

USING THE BATTERY PACK

You need a 7.2-volt rechargeable battery pack (Cat. No. 23-230, not
included) to power the vehicle.  Before you use the battery pack, use
the battery-pack charger (Cat. No. 23-241, not included) to charge it.
Your local Radio Shack store sells the proper battery pack and charger.

Cautions:  When you disconnect the battery pack from the charger, do not
           pull on the connector's wires or you might damage the battery
           pack.

           Do not overcharge the battery pack.  Doing so could damage it. 
           After you recharge the battery pack (12 to 14 hours),
           disconnect it from the charger.

           Use only recommended battery pack and charger.

           Do not charge the battery pack while it is in the vehicle.

Installing the Battery Pack

1.  Set the vehicle's ON/OFF switch to OFF.

2.  Lift the tab on the battery compartment lid and slide the lid back.
    Then swing the lid back on its hinge.

3.  Place the battery pack between the battery compartment and the back
    of the vehicle.  The battery pack's connector must be on the same side
    as the vehicle's matching connector.

4.  Attach the battery pack's connector to the vehicle's connector.  They
    fit together only one way.  Also, be sure the wires do not touch the
    back tires.

5.  Replace the lid.

Notes:  Ifthe vehicle loses power, recharge or replace the battery pack.

        At the end of the battery pack's useful life, it must be recycled
        or disposed of properly.  Contact your local, county, or state
        hazardous waste management authorities for information on
        recycling or disposal programs in your area.  Some options that
        might be available are: municipal curb-side collection, drop-off
        boxes at retailers, recycling collections centers, and mail-back
        programs.

ADJUSTING THE TRIM LEVERS

The neutral trim lever on the transmitter (next to the speed control) lets
you fine-tune the speed control so the vehicle stops completely when you
release the control.

The steering trim lever (next to the steering control) lets you fine-tune
the steering control so the vehicle goes straight when you release the
control.

Follow these steps to adjust the trim levers.

1.  Place the vehicle on a box or a wooden block so the tires do not
    touch the ground.

Note:  To ensure a precise adjustment, do not touch the tires during the
       adjustment procedure.

2.  Set the ON/OFF switches on the transmitter and the vehicle to ON.

3.  If the tires rotate, adjust the neutral trim lever until the tires
    stop.

    If the front tires angle left or right, adjust the steering trim lever
    so they point directly forward.

Note:  You might have to readjust the steering trim lever after you use
       the vehicle a few times.
