4.2 Collegamento del ricevitore

The receiver supports a voltage supply of 4-9V and both numerical and analog servo modes. Connect your servos and other components to the appropriate channels on the receiver.

• Connect the receiver to your RC vehicle's components (servos, ESC, etc.).
• Ensure all connections are secure and correctly oriented.

4.3 Processo di rilegatura

To establish communication between the transmitter and receiver, follow these steps:

• Assicurarsi che il trasmettitore sia spento.
• Insert the bind plug (codec) into the receiver's BIND/CH5 port.
• Power on the receiver. The LED on the receiver should start flashing.
• Press and hold the 'BIND' button on the transmitter while powering it on.
• Release the 'BIND' button once the transmitter powers on. The LED on the receiver should become solid, indicating successful binding.
• Power off both the transmitter and receiver. Remove the bind plug from the receiver.
• Power on the transmitter first, then the receiver. The system should now be bound and ready for operation.

• Ispezione: Periodically check all cables and connectors for signs of wear or damage. Ensure the antenna is not bent or broken.
• Cura della batteria: Always use recommended batteries and follow proper charging procedures for rechargeable types.

8. Risoluzione Dei Problemi

If you encounter issues with your HOTRC CT-4A system, refer to the following common troubleshooting steps:

• Nessun potere: Check battery installation and ensure batteries are fully charged or new. Verify the power switch is in the 'ON' position.
• Nessun problema di segnale/associazione: Re-perform the binding process as described in Section 4.3. Ensure the receiver is powered correctly and within range of the transmitter. Check for any interference from other 2.4GHz devices.
• Movimento irregolare del servo: Check all servo connections to the receiver. Ensure the receiver is receiving adequate power. Verify that the channel settings (positive/negative, stroke amount) are correctly configured.
• Gamma limitata: Ensure the transmitter and receiver antennas are not obstructed or damaged. Avoid operating in areas with high radio interference.
• I controlli non rispondono: Confirm the system is properly bound. Check if the fail-safe function has been triggered due to signal loss.
