RADIO SYSTEM
INSTALLING TRANSMITTER BATTERIES
Your TQi transmitter uses 4 AA batteries. The battery compartment
is located in the base of the transmitter.
1. Remove the battery compartment door by pressing the tab and
sliding the door open.
2. Install the batteries in the correct orientation, as indicated in the
battery compartment.
3. Reinstall the battery compartment door and snap it closed.
4. Turn on the transmitter and check the status LED for a solid
green light.
If the status LED flashes red, the transmitter batteries may be weak,
discharged or possibly installed incorrectly. Replace with new
batteries. The status LED does not indicate the charge level of the
battery pack installed in the model.
CHARGING THE RECEIVER BATTERY
To power the radio system in the truck, your Revo 3.3 is equipped
with the RX Power Pack, a rechargeable 5-cell NiMH battery pack.
The RX Power Pack must be fully charged before running the truck.
Use the supplied Molex adapter to connect the battery pack to the
included 2amp DC charger. The charger uses sophisticated voltage-
detection circuitry to monitor the battery and automatically stop
charging when the pack has reached maximum capacity. Revo
3.3 has a built-in charging jack, so you do not have to remove the
battery pack from the model for charging. Follow these steps to
fully charge the receiver battery before operating your model:
1. Plug the Molex end of the included adapter into the
charger. Plug the charger into a 12-volt automotive
auxiliary power socket. The charger is
compatible with 12-volt automotive
auxiliary power sockets only. The LED
on the charger will glow red to
indicate it is ready to charge
a battery.
Do not charge
batteries inside of an
automobile. Read the
Safety Precautions
section of this guide.
2. Plug the black connector of the adapter into
the charging jack located under the right front
of the truck. The charging jack is protected by a
rubber plug.
3. The charger’s LED will flash green, indicating that charging has
begun. The flashing green LED on the charger indicates the
charge progress.
4. When the battery is
fully charged, the LED
will light solid green.
See page 22 for more
information on charger
LED codes.
5. Unplug the charger from the power socket, and unplug the
adapter from the charger and the model. Replace the rubber plug
over the charging jack on the truck.
If the radio system doesn’t
appear to work when the
transmitter and receiver
switches are turned on,
check for correct battery
installation.

Use the Right Batteries
Your transmitter uses AA
batteries. Use new alkaline
batteries. Do not use
rechargeable AA cells to
power the TQi transmitter,
as they will not provide
sufficient voltage for optimum
transmitter performance.
Caution: Discontinue running
your model at the first sign of
weak batteries (flashing red
light on the transmitter) to
avoid losing control.
