4. Configuració
4.1 Instal·lació de la bateria
The transmitter supports two power supply methods: 2S lithium batteries or 4 AA batteries. The innovative detachable battery box allows direct insertion of a 2S lithium battery balance port.
- Open the battery compartment cover located at the bottom of the transmitter.
- Insert 4 AA batteries, observing correct polarity, or connect a 2S lithium battery to the designated port.
- Tanqueu bé la tapa del compartiment de la bateria.

4.2 Connexió del receptor
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 Binding Process
To establish communication between the transmitter and receiver, follow these steps:
- Assegureu-vos que el transmissor estigui apagat.
- 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.
5. Instruccions de funcionament
5.1 Controls bàsics
The CT-4A features an ergonomic pistol-grip and steering wheel for intuitive control. The throttle speed limit can be adjusted, and it includes brake and fail-safe functions.
5.2 Positive and Negative Channel Settings
This setting allows you to reverse the direction of specific channels if needed for your model.
Vídeo 5.1: Instructions for setting positive and negative channels on the HOTRC CT-4A transmitter. This video demonstrates how to adjust channel direction by holding the REV key and manipulating the CH1 handwheel or CH2 trigger. A sound indicates successful setting.
5.3 Stroke Amount Adjustment
Adjusting the stroke amount allows you to fine-tune the range of movement for your servos.
Vídeo 5.2: Guide on setting the stroke amount for the HOTRC CT-4A. This video shows how to enter adjustment mode by powering on the transmitter while holding the REV key, then using the trim buttons to adjust CH1 and CH2 stroke. The stroke is divided into 5 levels, with the default being the largest.
5.4 Mixing Control Setting
The CT-4A allows for mixed control mode on channels 1-2. This feature can be useful for specific vehicle configurations.
Vídeo 5.3: Demonstration of how to activate mixing control on the HOTRC CT-4A. To enable, press and hold the CH3 and CH4 switches simultaneously while powering on the remote control. The mixing indicator light on the panel will illuminate, confirming successful activation. The same method is used to disable it.
5.5 Out of Control Protection (Fail-Safe) Setting
The fail-safe function protects your model by setting predefined servo positions in case of signal loss, preventing loss of control.
Vídeo 5.4: Instructions for setting the out-of-control protection (fail-safe) function. First, ensure the code is successfully matched. Then, control the transmitter's throttle channel to the desired braking or stalling state. Insert the encoder into the receiver's bind pairing hole. The LED light will flash, then remain solid when the fail-safe is set. Test by turning off the transmitter power and observing if the throttle servo moves to the set position.
