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
or freshly charged batteries. The power indicator light does not
indicate the charge level of the battery pack installed in the model.
INSTALLING RECEIVER BATTERIES
The radio receiver in your Nitro 4-Tec uses 4 AA batteries. The receiver
battery holder is located underneath the top plate, just to the right of
the fuel tank.
1. Press the tab on
the reusable zip
tie to release the
battery holder.
2. Remove the battery
holder and install 4
AA alkaline batteries.
Make careful note of
the battery polarity using the diagrams in the
battery holder.
3. Stretch a rubber balloon over the battery
holder to prevent fuel contamination.
4. Install the battery holder into the car
and secure it to the top plate with the
reusable zip-tie. Make sure the battery
holder is secure in the model and will not
come loose to prevent interference with the
middle drive belt.
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 batteries.
Rechargeable batteries 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.
Your model can be upgraded with the RX
Power Pack NiMH rechargeable receiver
battery (part #3037). This battery eliminates
the 4-cell battery holder and the need to
replace alkaline batteries. Traxxas
recommends the EZ-Peak Plus charger (part
#2933) for recharging the battery. A special
wiring harness (part #3034) is required for the Nitro 4-Tec (includes a
handy external charging jack).
Traxxas’ integrated TRX Power System is the easiest way to add the
power and economy of rechargeable batteries to your Nitro 4-Tec.
Consult your hobby dealer for purchasing information.
