Petunjuk Pengaturan
- Mounting the Servo: Securely mount the servo into your RC vehicle's servo tray using the provided screws and brass inserts. Ensure the servo is firmly seated to prevent movement during operation.
- Connecting to Receiver/BEC: Connect the servo's 3-pin connector to the appropriate channel on your RC receiver. If using a separate Battery Eliminator Circuit (BEC), ensure it is properly connected and configured to supply the recommended voltage range (4.8V-8.4V) to the servo.
- Attaching Servo Horn: With the RC system powered on and the servo centered (usually by turning on the transmitter and receiver first), attach the desired servo horn to the servo output shaft. Ensure the horn is aligned correctly for your application. The included 25T metal servo horn is recommended for high-stress applications.
- Kalibrasi Awal: Before full operation, perform a basic calibration to ensure the servo responds correctly to your transmitter inputs. Check for full range of motion and proper centering.

Petunjuk Pengoperasian
The BLS-HV70MG servo operates with a control angle of 180 degrees, responding to standard PWM signals. The pulse width range for control is typically from 500 to 2500 microseconds, with 1500 microseconds representing the neutral position.
- Jil.tagRentang: This servo is designed for high voltage (HV) operation, accepting inputs from 4.8V to 8.4V. Operating within this range ensures optimal performance and longevity.
- Speed and Torque: The servo's speed and torque vary with the input voltage. Volume lebih tinggitages (e.g., 8.4V) will result in faster speeds (0.12sec/60°) and higher torque (71 Kg-cm).
- Kontrol: Use your RC transmitter to send control signals to the servo. Adjust the trim and sub-trim settings on your transmitter for precise centering and endpoint adjustments.

Pemeliharaan
Proper maintenance ensures the longevity and optimal performance of your servo.
- Pelapis kedap air: The servo has an IP67 waterproof rating. While it can withstand splashes and temporary immersion, avoid prolonged submersion or high-pressure water jets. After exposure to water, allow the servo to dry completely before storage.
- Pemeriksaan Gigi: Periodically inspect the metal gears for any signs of wear, damage, or debris. Clean any accumulated dirt or grime.
- Pembersihan: Use a soft, dry cloth to clean the exterior of the servo. Avoid using harsh chemicals or solvents.
- Penyimpanan: Store the servo in a dry, cool place away from direct sunlight and extreme temperatures.

Penyelesaian Masalah
- Servo Tidak Merespons:
- Check all connections between the servo, receiver, and power source.
- Ensure the receiver and transmitter are properly bound and powered on.
- Verifikasi volume catu dayatage is within the servo's operating range (4.8V-8.4V).
- Inconsistent Centering:
- Adjust the sub-trim on your transmitter.
- Check for any mechanical binding or obstruction in the linkage.
- Ensure the servo horn is securely attached and not stripped.
- Excessive Noise or Grinding:
- Inspect the gears for damage or foreign objects.
- Ensure the servo is not under excessive load or binding.
- Terlalu panas:
- Reduce the load on the servo if possible.
- Ensure adequate ventilation around the servo.
- Verifikasi input voltage. tidak terlalu tinggi.
