If the transmitter status LED 
doesn’t light green, check the 
polarity of the batteries. If you 
see any other flashing signal 
from the status LED, refer to 
the chart on page 40 to identify 
the code.
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 
LED) to avoid losing control.
Stop immediately at the first 
sign of weak batteries. Never 
turn the transmitter off when 
the model’s battery pack is 
plugged in. The model could 
run out of control.

INSTALLING RECEIVER BATTERIES
The radio receiver in your model uses 4 AA 
batteries. The battery holder for the receiver 
batteries is located underneath the battery 
cover. The battery cover can be identified by the 
on/off switch.
1. Access the battery compartment by removing 
the 4x12mm and 4x20mm buttonhead cap 
screws from the chassis. Swing the nerf 
bar out just far enough to clear the battery 
compartment cover.
2. Remove the battery holder and install 4 AA 
alkaline or rechargeable batteries. Make careful note of the battery 
polarity by comparing against the diagrams in the battery holder.
3. Insert the battery holder into the battery compartment.
4. Reinstall the battery compartment cover and secure with the screws.
To prevent losing control of your model, it is important to 
stop at the first sign of weak receiver batteries to avoid losing 
control. Visible warning signals include sluggish steering 
response and shortened radio range.
INSTALLING TRANSMITTER BATTERIES
Your TQi 2.4GHz 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 power indicator light does not indicate the charge level of the 
battery pack installed in the model. Refer to the Troubleshooting 
section on page 40 for more information on the transmitter’s status 
LED codes.
Optional Accessory: Rechargeable Receiver Battery
The Slayer Pro 4X4 can be upgraded with the RX 
Power Pack NiMH rechargeable receiver battery 
(part #3036). This battery eliminates the 4-cell 
battery holder and the need to replace alkaline 
batteries. Traxxas recommends the EZ-Peak Plus 
Charger (part #2970) or the EZ-Peak Dual Charger 
(part #2972) for recharging the battery.
