VK-R4A Receiver Function Instructions
VK-R4A based on ANT protocol is a three-in-one receiver with ESC and LED light group control
board. It has an external single antenna, can output PWM signal and light control signal, can
implement two-way transmission, adopts automatic binding, and has a compact design, which
can be adapted to various models.
6.1 Attentions
•
Make sure the product is installed and calibrated correctly, failure to do so may result in
serious injury.
•
Please carefully check each power device and car frame instructions to ensure the power
matching is reasonable before use. Avoid damaging power system due to incorrect matching.
•
Do not let the external temperature of the system exceed 90
℃
/194
℉
, because high
temperature will damage the power system.
•
Make sure the receiver's battery is disconnected before turning off the transmitter, failure to
do so may lead to unintended operation or loss of control.
•
After use, remember to disconnect the battery and the ESC. If the battery isn't disconnected,
the ESC will consume electric energy all the time even if it is off. It will discharge completely if
connect the battery for a long time, thus resulting in the failure of the battery or the ESC. We
are not responsible for any damage caused by this!
•
Make sure the receiver is mounted away from motors or any device that emits excessive
electrical noise.
•
Keep the antenna of the receiver at least 1cm away from conductive materials such as carbon
or metal.
•
Do not power on the receiver during the setup process to prevent loss of control.
6.2 Use Guidance
1
.
Connect related equipment.
• Make sure the ESC is off before connection. Connect the motor with M+ and M- of ESC.
Connect the steering servo to the 3Pin interface marked with “ST” of ESC (- + S connected
correspondingly). Connectthe battery with the positive and negative poles of ESC correspondingly.
Tips
：
If the rotation direction is not correct during running, exchange the two wires connecting motor
and ESC.
2. Normal boot, identification throttle midpoint
• After connecting related equipment as step 1, turn on the radio first, move the throttle trigger to
the neutral position. Turn on the switch of ESC at last. The receiver will automatically recognize
the battery type when it is powered on again. Then it can run it.
