AVc
®
– ActiVe Vehicle cOntROl
™
The Spektrum SRS4220 receiver features Active Vehicle Control
™
(AVC
®
)
technology that responds similar to traction control in full-scale vehicles. In
addition to traction control, AVC technology also increases steering stability
during high speed driving or while driving over rough terrain. As you increase
the AVC sensitivity, the system increases steering stability and traction control,
similar to reducing the amount of steering rate in a computer transmitter.
Reducing the sensitivity value increases the amount of steering control from the
transmitter. The SRS4220 receiver also enables you to quickly turn AVC on or off
if you participate in organized racing.
imPORtAnt:
You must use digital servos with the SRS4220 receiver. Do not use
analog servos as they will reduce the performance of the system and may cause
overheating.

sensitiVity
The AVC/ST RATE dial adjusts the sensitivity, or stability, value in the receiver.
If you increase the sensitivity, the AVC
®
system becomes more sensitive to the
vehicle drifting left or right. You would use maximum sensitivity during high
speed driving or drag racing, when you want the vehicle to stay in a straight line.
As the sensitivity value increases, the amount of steering travel decreases.
Turn the AVC/ST RATE knob counter-clockwise to
reduce the sensitivity.
Turn the AVC/ST RATE knob clockwise to increase the
sensitivity.
imPORtAnt:
The AVC/ST RATE knob will only adjust
the sensitivity when the transmitter is bound to a
DSMR
®
receiver. When the transmitter is bound to a DSM2
®
receiver, the AVC/ST
RATE knob controls the steering dual rate.
Binding
Binding is the process of programming the receiver to recognize the GUID
(Globally Unique Identifier) code of a single specific transmitter. When a receiver
is bound to a transmitter/model memory, the receiver will only respond to that
specific transmitter/model memory.
your spektrum dX2e comes prebound to the vehicle. if you need to
rebind or calibrate, follow the instructions below.
1. With the vehicle on a flat, level surface, insert the Bind Plug in the BIND port
on the receiver.
2. Connect a fully charged battery pack to the ESC.
3. Power on the ESC. The orange LED flashes, indicating the receiver is in bind
mode.
4. Center the ST TRIM and TH TRIM dials on the transmitter.
5. Press and hold the BIND button while powering on the transmitter.
6. Release the BIND button when the orange LED slowly flashes. The transmitter
and receiver are linked when the orange LED is solid.
cAliBRAting (continue from step 6 above)
7. Pull the transmitter trigger to Full Throttle.
8. Push the transmitter trigger to Full Brake, then return the trigger to center.
9. Turn the transmitter steering wheel to Full Right.
10. Turn the transmitter steering wheel to Full Left, then return the steering
wheel to center. The orange LED flashes once.
11. Remove the Bind Plug, then power off the receiver to save the settings.
12. Power off the transmitter.

technOlOgy
If you participate in organized racing, you may be required to turn AVC off. To
turn AVC off:
1. Insert a Bind Plug in the BIND port on the receiver.
2. Insert a second Bind Plug in the DISABLE port on the receiver.
3. Follow the BINDING AND CALIBRATING
steps above to finish disabling AVC.
4. Remove the Bind Plugs, then power off the receiver to save the settings. The
receiver will continuously blink to indicate AVC is disabled.
imPORtAnt:
You must calibrate the receiver each time it is placed in bind
mode. To activate AVC, see the Binding/Calibrating steps above.
