4. 설정 가이드
4.1. 송신기 배터리 설치
The NB-7D transmitter requires 4x AA batteries (not included). To install:
- Locate the battery compartment on the base of the transmitter.
- 배터리 덮개를 밀어서 엽니다.
- AA 배터리 4개를 올바른 극성(+/-)에 맞춰 넣으세요.
- 배터리 덮개를 단단히 닫으세요.
4.2. Receiver and Component Connection
Connect your RC model's components to the RX-G7X receiver as follows. Refer to Figure 4.1 for port identification:
- 채널 1(CH1): 스티어링 서보
- 채널 2(CH2): Electronic Speed Controller (ESC) / Throttle
- 채널 3-7 (CH3-CH7): Auxiliary functions (e.g., additional servos, gear shifts).
- Light Slots (HL, PL, BL, RL, CLR, CLL): Connect the 12-LED light set or other compatible LED lights.
- Winch Slot (M1): Connect your RC winch.

Figure 4.1: Transmitter controls and Receiver port assignments.
4.3. 송신기와 수신기 결합
송신기와 수신기 간의 통신을 설정하려면:
- 송신기의 전원이 꺼져 있는지 확인하세요.
- Connect the receiver to power (e.g., via ESC or a separate battery). The receiver's LED will flash rapidly.
- Press and hold the "BIND" button on the receiver (refer to Figure 4.2).
- BIND 버튼을 누른 상태에서 송신기를 켭니다.
- The receiver's LED should turn solid, indicating a successful bind. Release the BIND button.
- Turn off both the transmitter and receiver, then turn them back on in sequence (transmitter first, then receiver) to confirm the bind.

5. 사용 설명서
5.1. 기본 제어
- 스티어링 휠(CH1): Rotate left or right to control the steering of your RC model.
- 스로틀 트리거(CH2): 당기면 앞으로 가속하고, 밀면 브레이크 또는 후진합니다.
- 전원 스위치: Located on the front of the transmitter, turns the unit on/off.
5.2. Advanced Control Functions
The NB-7D transmitter offers several adjustable settings for fine-tuning control:
- ST.TRIM(스티어링 트림): Adjusts the neutral position of the steering. Use if the vehicle pulls to one side when the steering wheel is centered.
- TH.TRIM(스로틀 트림): Adjusts the neutral position of the throttle. Use if the vehicle moves slightly forward or backward when the throttle trigger is at neutral.
- ST D/R (Steering Dual Rate): Adjusts the maximum steering angle. Lowering this value reduces the steering sensitivity, useful for high-speed driving.
- TH D/R (Throttle Dual Rate): Adjusts the maximum throttle output. Lowering this value reduces the maximum speed, useful for beginners or confined spaces.
- Steering Reverse Switch (ST.REV): 조향 방향을 반대로 합니다.
- 스로틀 역회전(TH.REV): 스로틀 방향을 반대로 합니다.
- CH5, CH6, CH7 Knobs: Control auxiliary channels 5, 6, and 7 respectively. These can be assigned to various functions on your RC model.
- MIX/LED Button: Toggles between General Mode and Mixed Mode, and also controls the LED light system.
- 설정 버튼: Used for various settings and programming functions.
5.3. Light Control System
The integrated light control system allows for realistic lighting effects:
- Connect the 12-LED light set to the corresponding light slots on the RX-G7X receiver (HL: Headlights, PL: Park lights, BL: Backup lights, RL: Right Cornering Light, CLR: Clear, CLL: Clear).
- Use the MIX/LED button on the transmitter to cycle through different light modes or turn lights on/off.
5.4. Mixed Control Function
The multi-channel mixing control function allows you to link multiple channels on the receiver to be controlled by a single channel on the transmitter. This is useful for complex setups requiring synchronized movements.

Figure 5.1: Transmitter in General Mode (factory default setting).

Figure 5.2: Transmitter in Mixed Mode (supports mix control of channel 1 and channel 2).
5.5. Winch Control
Connect your RC winch to the M1 slot on the receiver. Control of the winch will typically be assigned to one of the auxiliary channels (CH5, CH6, or CH7) on the transmitter, depending on your setup and model's requirements.

Figure 5.3: Winch connection to the RX-G7X receiver.
5.6. 낮은 볼륨tage 표시
The LED indicator on the transmitter will flash slowly when the battery voltage drops below 4.2V. This serves as a warning to replace the batteries to prevent loss of control.
6. 유지관리
- 청소: 부드럽고 마른 천을 사용하여 송신기와 수신기를 청소하십시오. 용제나 강한 화학 물질은 사용하지 마십시오.
- 배터리 관리 : 장기간 사용하지 않을 경우 누출을 방지하기 위해 송신기에서 배터리를 제거하세요.
