4. Nastavení: Párování přijímače
Follow these steps to bind your R4FGM receiver to a compatible Radiolink transmitter:
- Zapnutí přijímače: Connect the R4FGM receiver to a power source (3.0-10V). The LED indicator on the receiver will flash slowly, indicating it is not yet bound.
- Zahájení vazby: Long press the binding button on the receiver. The LED indicator will begin to flash quickly, signifying that the binding process is active. Release the button.
- Zapnutí vysílače: Turn on your compatible Radiolink transmitter.
- Potvrzení vazby: Once the binding is successful, the LED indicator on the receiver will stop flashing and remain solid green. Additionally, a signal tower icon will appear on the LCD screen of your transmitter, confirming a successful connection.
- Test připojení: Connect a servo to the receiver and operate the steering wheel on your transmitter to verify that the servo responds correctly.

5. Operation: Gyro Function
The R4FGM receiver features an integrated gyroscope to assist with vehicle stability. You can easily control and adjust this function:
- Toggle Gyro Mode: To switch the gyro mode ON or OFF, short press the binding button on the receiver three times within one second.
- LED Indicator for Gyro: A red LED indicates the gyro is ON, while a green LED indicates the gyro is OFF.
- Adjust Gyro Sensitivity: On your compatible Radiolink transmitter (e.g., RC4GS V2/V3, RC6GS V2/V3), navigate to the 'Gyro' menu. Ensure 'MIX' is ON and 'MODE' is set to 'VR'. You can then turn the VR knob on your transmitter to adjust the gyro sensitivity to your preference.

7. Údržba
To ensure the longevity and optimal performance of your R4FGM receiver, consider the following maintenance tips:
- Udržujte v suchu: While robust, avoid exposing the receiver to excessive moisture or water. If used in environments where water exposure is possible, consider additional waterproofing measures.
- Jemně čistěte: Use a soft, dry cloth to clean the receiver. Avoid harsh chemicals or solvents.
- Správné skladování: Pokud přijímač nepoužíváte, skladujte jej na chladném a suchém místě mimo dosah přímého slunečního záření a extrémních teplot.
- Zabezpečená připojení: Pravidelně kontrolujte všechna kabelová připojení, abyste se ujistili, že jsou bezpečná a nepoškozená.
8. Řešení problémů
If you encounter issues with your R4FGM receiver, consider these common troubleshooting points:
- Přijímač není vázán: Ensure your transmitter is a compatible Radiolink model. Verify that the receiver is powered correctly (3.0-10V) and that you are performing the binding sequence (long press button until fast flashing, then release).
- Žádný signál/rušení: Check the antenna placement on the receiver and ensure it is not obstructed. Confirm that there are no strong interference sources nearby. The FHSS algorithm provides good anti-interference, but extreme conditions can still affect performance.
- Gyro Not Working: Ensure the gyro mode is activated (red LED on receiver). Check your transmitter's gyro settings (MIX ON, MODE VR) and adjust sensitivity.
- Servo nereaguje: Verify that the servo is correctly plugged into the receiver and receiving power. Check the binding status between the receiver and transmitter.
