Configurazione e installazione
- Collegamento elettrico: Before initial use, ensure the servo is powered on (within the specified voltage range) and allowed to return to its neutral position.
- S-U300: Requires 4.8V to 6.0V DC.
- S-U400: Requires 6.6V to 7.4V DC (High VoltagE).
Caution: Do not use dry cell batteries as a power source for the servo. Ensure the power supply matches the servo's voltage requisiti.
- Montaggio: Securely mount the servo within your RC model's frame using appropriate hardware. Ensure there is no binding or obstruction to the servo's movement.
- Configurazione del collegamento: After the model's frame is assembled, set the maximum stroke of the servo. This stroke must be consistent with the physical travel limits of the control surface or mechanism it operates to prevent damage to the servo or model.
- S.BUS Compatibility: These servos support the S.BUS method for simplified wiring and setup with compatible receivers. Refer to your receiver's manual for S.BUS connection details.

Istruzioni per l'uso
FUTABA digital servos provide precise and responsive control. Once installed and calibrated, they will respond to commands from your RC transmitter via the receiver.
- Ensure your transmitter and receiver are properly bound and configured according to their respective manuals.
- Always perform a range check before operating your model to ensure reliable control.
- Avoid applying excessive force to the servo horn, as this can damage the internal gears or motor.
- Monitor servo temperature during operation, especially in demanding applications. Overheating can lead to reduced performance and premature failure.
Manutenzione
- Pulizia: Keep the servo clean and free from dirt, dust, and moisture. Use a soft, dry cloth for cleaning.
- Ispezione: Regularly inspect the servo case for cracks or damage, and check the servo wires for fraying or loose connections.
- Ispezione degli ingranaggi: Periodically check the servo gears for wear. While these servos feature durable resin gears, heavy use or crashes can cause wear.
- Magazzinaggio: Store servos in a dry, cool environment away from direct sunlight and extreme temperatures.
Risoluzione dei problemi
- Servo non risponde:
- Check power supply: Ensure the servo is receiving the correct voltage (4.8-6.0V for S-U300, 6.6-7.4V for S-U400).
- Verify connections: Ensure the servo is correctly plugged into the receiver.
- Check transmitter/receiver: Confirm that the RC system is powered on and functioning correctly.
- Erratic Movement or Jittering:
- Interference: Check for sources of electrical interference near the servo or receiver.
- Fluttuazioni di potenza: garantire un'alimentazione elettrica stabile.
- Damaged gears: Inspect gears for signs of wear or damage.
- Weak or Slow Response:
- Basso volumetage: Ensure the power supply is adequate and fully charged.
- Binding: Check for mechanical binding in the linkage system that might be overloading the servo.

Suggerimenti per l'utente
- Quantity Clarification: The product is typically sold as a single servo unit. If you require multiple servos, please ensure you adjust your order quantity accordingly.
- Voltage Corrispondenza: Always double-check that your power source voltage matches the specific requirements of your S-U300 (4.8-6.0V) or S-U400 (6.6-7.4V) servo to prevent damage.
- Linkage Freedom: Ensure all linkages connected to the servo move freely without any binding. Binding can cause the servo to draw excessive current, leading to overheating and premature failure.
- S.BUS Advantage: If your RC system supports S.BUS, utilize it for a cleaner wiring setup and potentially easier configuration of multiple servos.
