5. Binding and Operation

5.1 Binding Procedure (Contra-frequency method)

1. Ensure your remote control is turned off.
2. Repeatedly turn the receiver power ON and OFF three times. The receiver's status light will flash twice, indicating it has entered the frequency binding mode.
3. Turn on your remote control. Access the EXPRESS LUA interface and select the "BIND" option to confirm the binding process.
4. Once the receiver's status light remains steadily ON, the frequency setting is successful, and the receiver is bound to your remote control.

5.2 Status Light Indications

The receiver's status light provides important feedback on its current state:

5.3 Telemetry and Upgrades

The HR7C receiver supports RSSI feedback, providing real-time signal strength information. Additionally, when operating in D8 mode, it supports voltage feedback, allowing for automatic switch detection. The receiver also supports convenient WiFi upgrades and settings for firmware updates and configuration adjustments.

6. Maintenance

• Keep the receiver clean and free from dust, dirt, and moisture.
• Regularly inspect antenna connections for any signs of damage or wear.
• Ensure proper ventilation around the receiver to prevent overheating during operation.
• Avoid exposing the receiver to extreme temperatures or direct sunlight for prolonged periods.

7. Troubleshooting

• Receiver not connecting/no signal:
  • Review the binding procedure (Section 5.1) and check the status light indications (Section 5.2).
  • Ensure the remote control is powered on and correctly configured.
  • Verify the receiver's power supply is within the 4.5-8.4V range and correctly connected.
  • Confirm that both the remote control and receiver are set to compatible signal formats (D8/D16v1/SFHSS).
• Intermittent signal loss:
  • Check antenna placement; ensure they are not obstructed, bent, or damaged.
  • Verify that the operating distance is within the specified control range (greater than 1km).
  • Identify and eliminate potential sources of radio interference in your operating environment.
• No telemetry data displayed:
  • Ensure your remote control system supports telemetry display.
  • Confirm the receiver is properly bound and configured for feedback (especially for D8 voltage feedback).
