2. Setup
2.1. Installation
The AR620 features an internal antenna design, simplifying installation. Position the receiver securely within your model, ensuring it is protected from vibrations and potential damage. The compact footprint allows it to fit in a wide range of models.
2.2. Binding Process
The AR620 utilizes a large bind button, eliminating the need for traditional bind plugs. To bind the receiver to your Spektrum transmitter:
- Ensure your transmitter is powered off and the model's power source is disconnected.
- Press and hold the bind button on the AR620 receiver.
- While holding the bind button, connect power to the receiver. The receiver's LED will begin to flash rapidly, indicating it is in bind mode.
- Release the bind button.
- Put your Spektrum transmitter into bind mode (refer to your transmitter's manual for specific instructions).
- Once binding is successful, the receiver's LED will glow solid, indicating a successful connection.
- Disconnect power from the receiver, then power off your transmitter.
- Reconnect power to the receiver and then power on your transmitter. The system should now be linked.
The AR620 supports two bind-sequence options, allowing flexibility in how you initiate the binding process (either while powering up or after power is connected).
3. Operation
3.1. Telemetry
The AR620 is integrated with fly-by range telemetry, providing valuable flight data. This includes flight log information and receiver battery pack voltage data. Access to this telemetry is automatic when used with telemetry-capable Spektrum transmitters. No additional setup is required to monitor receiver battery voltage, offering immediate peace of mind regarding your power source.
3.2. SmartSafe Failsafe
The SmartSafe Failsafe feature is designed to enhance safety. In the event of signal loss, this system locks the throttle position of your model until the receiver has successfully initialized and confirmed a stable lock to the transmitter. This prevents unintended throttle inputs during signal interruptions, providing an added layer of protection for your model.
4. Maintenance
The Spektrum AR620 receiver is designed for durability. To ensure optimal performance and longevity:
- Keep the receiver clean and free from dust, dirt, and moisture.
- Avoid exposing the receiver to extreme temperatures or direct sunlight for prolonged periods.
- Ensure all connections to the receiver (servo leads, power) are secure and free from corrosion.
- Periodically inspect the receiver for any signs of physical damage.
- Store the receiver in a dry, cool environment when not in use.
5. Troubleshooting
5.1. Receiver Not Binding
- Ensure the transmitter is in bind mode and the receiver's LED is flashing rapidly before releasing the bind button.
- Verify that the receiver is receiving adequate power.
- Check for any interference sources nearby.
- Confirm that your transmitter is compatible with DSMX/DSM2 receivers.
5.2. Loss of Signal / Intermittent Control
- Check the range of your system. Ensure you are within the operational range of your transmitter.
- Inspect all wiring for loose connections or damage.
- Ensure the receiver is not obstructed by carbon fiber or other conductive materials that can block RF signals.
- Verify the receiver battery voltage using the telemetry feature. A low battery can cause signal issues.
5.3. Servos Not Responding
- Confirm the receiver is successfully bound and its LED is solid.
- Check that servos are correctly plugged into the appropriate channels on the receiver.
- Ensure the power supply to the receiver and servos is sufficient.
