4. Setup

4.1 Battery Installation (Transmitter)

1. Open the battery compartment cover on the bottom of the transmitter.
2. Insert four (4) 'AA' batteries, ensuring correct polarity (+/-).
3. Close the battery compartment cover securely.

Note: The transmitter requires 4 'AA' batteries (not included).

4.2 Receiver Installation and Connections

1. Mount the RX-G4 receiver securely in your RC vehicle, away from motors, ESCs, and other sources of electrical interference.
2. Connect your steering servo to the CH1 port on the receiver.
3. Connect your Electronic Speed Controller (ESC) to the CH2 port on the receiver.
4. Connect any optional accessories (e.g., additional servos, light modules) to the CH3, CH4, -HL, -CL-R, and -CL-L ports as required.

Important: This transmitter is only compatible with the receiver included in this set. Ensure all connections are firm and correctly oriented.

4.3 Binding the Transmitter and Receiver

Binding is the process of linking the transmitter and receiver. This system is typically pre-bound from the factory. If re-binding is necessary:

1. Ensure the transmitter is powered off.
2. Power on the receiver (via the ESC or a separate battery). The receiver's LED will likely flash, indicating it's not bound.
3. Press and hold the BIND button on the receiver.
4. While holding the BIND button, turn on the transmitter.
5. Release the BIND button on the receiver once the receiver's LED becomes solid, indicating a successful bind.
6. Turn off both the transmitter and receiver, then power them on again in the correct sequence (transmitter first, then receiver) to confirm the bind.

5. Operating Instructions

5.1 Basic Control

• Steering: Rotate the steering wheel left or right to control the vehicle's direction.
• Throttle: Pull the throttle trigger back for forward movement. Push the trigger forward for braking, then push further for reverse.

5.2 CH1 & CH2 Mixing Control

This feature allows simultaneous control of steering and throttle through a single input. To activate:

1. Hold the SET button.
2. Long press the POWER button for 2 seconds.
3. The system will enter mixing control mode. You can now control both steering and throttle using either the throttle stick or the steering wheel, depending on the specific mixing setup.

5.3 Light Control System

The transmitter features a built-in light control system, allowing easy operation of connected lights.

Figure 4: Demonstrating light control with the transmitter.

• Use the CH3 and CH4 buttons to control connected accessories, such as headlights, right cornering lights, and left cornering lights, if wired to the corresponding receiver ports.

5.4 Adjusting Dual Rate (D/R)

The ST D/R and TH D/R knobs adjust the sensitivity and maximum travel of the steering and throttle channels, respectively. This allows fine-tuning for different driving conditions or personal preference.

Figure 5: Location of Steering and Throttle D/R adjustments.

• Rotate the ST D/R knob to increase or decrease the steering throw.
• Rotate the TH D/R knob to increase or decrease the throttle response.

6. Maintenance

• Cleaning: Use a soft, dry cloth to clean the transmitter and receiver. Avoid using solvents or harsh chemicals.
• Storage: Store the radio system in a cool, dry place away from direct sunlight and extreme temperatures. Remove batteries from the transmitter if storing for extended periods to prevent leakage.
• Battery Check: Regularly check the transmitter batteries for low voltage. The Power LED will indicate low battery status.
