2. Setup and Installation

Proper installation is crucial for safe and reliable operation of your RC model.

Mounting Guidelines

• Mount the receiver away from motors, electronic speed controllers (ESCs), or any devices that emit significant electrical noise.
• Ensure the receiver's antenna is positioned at least 1cm away from conductive materials like carbon fiber or metal to maintain optimal signal reception.

Physical Dimensions

3. Binding Procedure

Binding connects your FS-FGR4 receiver to your Flysky Noble FS-NB4 transmitter, establishing a secure communication link.

1. Insert the bind cable into the receiver's BIND port.
2. Plug the power cable into any other available port. The receiver's LED will begin to flash rapidly, indicating it has entered bind mode.
3. Activate bind mode on your transmitter. Refer to your transmitter's instruction manual for specific steps.
4. Binding is successful when the receiver's LED changes to a slow flash.
5. Remove both the power and bind cables from the receiver.
6. Reconnect the power cable to the receiver.
7. Verify that the transmitter and receiver function as expected. If any issues occur, repeat the binding process.

4. Forced Update

If the receiver fails to bind after a transmitter update, a forced update of the receiver may be necessary.

1. Short-circuit the BIND port and its separated signal pins using the bind cable. (Refer to the Receiver Components diagram for port identification).
2. Power on the receiver to enter update mode. The receiver's LED will flash in a pattern of three flashes followed by one off.
3. Unplug the bind cable.
4. Select the "forced update" option on your transmitter.
5. The update is complete when the receiver's LED changes from the three-flash pattern to a slow flash.

5. Failsafe Function

The failsafe function is a safety feature designed to protect your model and personnel in the event of signal loss between the receiver and transmitter.

• If the transmitter has not been configured with specific failsafe channel values, the PWM, PPM, and i-bus outputs will cease, while the S.bus output will maintain its last known state.
• If failsafe values are set on the transmitter, the receiver will output these predefined channel values upon signal loss.

6. Operating and Compatibility

Once successfully bound, the receiver will operate in conjunction with your transmitter. Ensure your transmitter is compatible with the AFHDS3 protocol.

Compatibility

The FS-FGR4 receiver is compatible with various Flysky AFHDS3 transmitters. Refer to the table below for specific compatibility details.

7. Maintenance

The FS-FGR4 receiver requires minimal maintenance. Keep it clean and dry. Avoid exposing it to extreme temperatures or moisture. Regularly inspect connections for any signs of wear or damage.

8. Troubleshooting

• Receiver Not Binding: Ensure the bind cable is correctly inserted and the power is connected. Verify the transmitter is in bind mode. If issues persist, attempt a forced update as described in the "Forced Update" section.
• Unexpected Operation: Re-bind the receiver to the transmitter. Check all cable connections and ensure the receiver is mounted away from sources of electrical interference.
• Loss of Control: Verify antenna placement is at least 1cm from conductive materials. Ensure the receiver's battery is adequately charged. Review failsafe settings on your transmitter.
