The receiver enters the waiting-for-connection state upon power-on, waiting for the connection to the bound transmitter. If the receiver does not connect the bound transmitter within 2S, it automatically enters the binding state. This state lasts for 10S. If the binding with the transmitter is successful, it enters the normal connection state, otherwise, it exits the binding state and returns to the waiting-for-connection state. Note: In case of binding, the receiver LED flashes quickly. In case of waiting-for-connection, the receiver LED flashes slowly. In case of normal connection, the receiver LED is solid on. The binding steps are as below. 1. First put the transmitter into bind mode (See the transmitter's user manual for instructions on how to activate bind mode.). 2. When the receiver is powered on and waits for 2 seconds, it will automatically enter the binding state if it is not connected. 3. After the binding is successful, the LED indicator of the receiver is solid on. Note: Set the transmitter to its binding state first, and then set the receiver to its binding state. If the binding is not finished within 10S, the LED of the receiver will enter its slow flashing state. Protection CH2 CH1 CH3 The receiver supports the low voltage protection function. Low Voltage Protection: The receiver will enter the low voltage protection state in case of detecting low voltage, all channels won't output, and the car light will flash slowly for prompt. The receiver supports the overheating protection and the blocking protection function. Overheating Protection: The receiver will enter the overheating protection state in case of the high internal temperature of the ESC, the CH2 motor channel won't output, but the other channels will output normally. The CH2 motor channel will output normally when the temperature is normal. Blocking Protection: When the external motor is blocked, it enters the blocking protection state, to protect the ESC and the motor. FMS-R3A1 Receiver Car Light Control BIND When the receiver and the transmitter has connected normally, press the BIND button of the transmitter to turn on or turn off the car llight. By default, the car light is off. ESC Running Mode

[ ] 55%70% 100%

ESC Running Mode The running mode can be set to Forward/Reverse/Brake mode or direct Forward/Reverse mode, and by default, the running mode is direct Forward/Reverse mode. When the running mode is set to Forward/Reverse/Brake mode, the maxmam brake force can be set to 55%, 70% or 100%

through the transmitter. Note: The running mode of the ESC can be set at the transmitter side which is bound with the receiver. For the details, refer to the transmitter manual. Failsafe CH2 CH1CH3 CH1CH3 The failsafe function is used to protect the model and personnel when the receiver is out-of-control. The CH2 channel will enter the brake state when the receiver is out-of-

control. By default, the CH1 and CH3 channels are not set, and these two channels will maintain the last output in case of out-of-control. You can set the failsafe value for CH1 and CH3 channels at the transmitter side. 1 Attentions:

Make sure the product is installed and calibrated correctly, failure to do so may result in serious injury. Make sure the receiver's battery is disconnected before turning off the transmitter, failure to do so can result out of control. Unreasonable setting of the Failsafe may cause accidents. Make sure the receiver is mounted away from motors, electronic speed controllers or any device that emits excessive electrical noise. Keep the receiver's antenna 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. FMS-R3A1 Receiver Certifications FCC Compliance Statement This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Warning: changes or modifications not expressly approved by the party responsible for compliance could void the users authority to operate the equipment. This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

-- Reorient or relocate the receiving antenna.

-- Increase the separation between the equipment and receiver.

-- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

-- Consult the dealer or an experienced radio/TV technician for help. EU DoC Declaration Hereby, we declare that the Radio Equipment [FMS-R3A1] is in compliance with RED 2014/53/EU. RF Exposure Compliance This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20 centimeters between the radiator and your body. Environmentally friendly disposal Old electrical appliances must not be disposed of together with the residual waste, but have to be disposed of separately. The disposal at the communal collecting point via private persons is for free. The owner of old appliances is responsible to bring the appliances to these collecting points or to similar collection points. With this little personal effort, you contribute to recycle valuable raw materials and the treatment of toxic substances.
