User Manual

2. Apply power to the receiver. It can be from 3.7 to 8.4 volts DC. Please refer to
picture on the side of the receiver for the correct pinout
(GND, VCC, SIGNAL)
3. You will see the orange LED rapidly blinking. That means the receiver is in Bind
mode.
4. Follow the procedures of your specific transmitter to enter Bind Mode, the
system will connect within a few seconds. Once connected,
the orange LED on the receiver will blink several times and go solid indicating the
system is connected.
If binding is not successful try to move receiver at least 2-3 meters from
transmitter during binding. Receiver is extremely sensitive
and close proximity to the transmitter oversaturates it.
5. Remove the bind plug from the BIND and THRO ports on the receiver before
you power off the transmitter and store it in a convenient
place.
After you’ve set up your model, it’s important to rebind the system so the true
low throttle and neutral steering positions are set.
NOTICE:
Remove the bind plug to prevent the system from entering bind mode the next
time the power is turned on.
Smart Failsafe Feature
The GR300R features failsafe. It remembers the steering wheel and throttle
trigger positions during the bind process with your transmitter.
(generally full brake and neutral steering). This stores the failsafe positions.
Continue to hold the failsafe positions until the binding process is
complete. When the signal is regained, the system immediately regains control.
When the receiver only is turned on (no transmitter signal is present), the throttle
channel has no output, to avoid operating or arming the
electronic speed control. All other channels are driven to their preset failsafe
positions set during binding.
