2.3 Receiver Overview BIND SERVO SENS Status Indicator 2.3.1 Status Indicator The status indicator is used to indicate the power and working status of the receiver. • • • • Off: The power is not connected. Lit in red: The receiver is on and working. Flashing quickly: The receiver is binding. Flashing slowly: The bound transmitter is off or signal is lost.
3. Getting Started Before operation, install the battery and connect the system as instructed below. 3.1 Transmitter Battery Installation Danger • Only use included batteries Danger • Do not crush/puncture the battery, or short the external contacts. Danger • Do not open, disassemble, or attempt to repair the battery. Danger • Do not expose to excessive heat or liquids. Danger • Do not drop the battery or expose to strong shocks or vibrations. Danger • Do not use the battery if damaged.
4. Operation Instructions After setting up, follow the instructions below to operate the system. 4.1 Power On Follow the steps below to turn on the transmitter: 1. Make sure that： • The battery is fully charged and installed correctly. • The receiver is installed correctly and powered down. 2. Hold the power button until the screen turns on. 3. Connect the power supply to the receiver. Note • • Note Operate with caution in order to avoid damage or injury.
5. System Interface The main interface mainly displays information related to the model, such as transmitter voltage information, function status and so on. Model Name To be added Sensors Function Status Bar Steering Channel Throttle Channel Channel 3 Channel 4 Steering Trim Trigger Trim Hold the lock icon for 2 seconds to lock or unlock the screen. Menu Icon Function Status Bar The function status bar displays the status of various functions.
6. Function Settings This section details functions and their use. 6.1 Reverse The Reverse function is used to correct a servo or motor's direction in relation to the systems controls. For example, if a steering servo is mounted upside down in order to fit inside a model, when the system's steering wheel is turned, the servo will move in the opposite direction. To fix this, all we need to do is reverse CH1. Use: 1. Touch the box next to the channels name.
6.4 Steering Exponential This function changes the steering channel's response curve. There are 2 main parameters: • Rate: Changes the outer limits of the steering, the default and maximum is 100%. • Exp. (Exponential): Changes the steering curve, which changes the response of the steering wheel. The Exp. setting can be positive or negative. Changes to the rate and exponential can be seen on the graph located in the center of the screen.
6.7 Throttle Neutral Throttle Neutral creates a configurable dead zone for the throttle channel. Forward: How far the dead zone extends into the throttle zone. Dead Zone: The point at which the channel will kick in when the trigger passes the threshold. Backward: How far the dead zone extends into the braking zone. Setup： 1. Touch "Forward", "Dead Zone" or "Backward" to select it. 2. Use the + and - icons to to change the percentage as needed. 3. Repeat with other settings as needed. 4.
6.10 A.B.S. A.B.S. stands for auto breaking system. This function is used to stop the wheels from locking which can lead to loss of control or a skid. A.B.S. manages this by regulating the amount of pressure the breaks use, which is done by pumping the breaks on and off rather than a constant force. There are six sub menus for A.B.S. function setting, [Brake return], [Delay], [Cycle length], [Trigger point], [Duty cycle], and [Steering mix].
Duty Cycle Changes the length of each pulse and the gap between them. As the value changes, the length of the braking waves peaks and troughs will change independently of each other and will no longer be symmetrical. Steering Mix A.B.S. can be reduced automatically while turning. This function mixes braking and steering to turn reduce the A.B.S. or replace it with a constant braking pressure.v 6.11 Throttle Speed Throttle Speed changes how quickly the throttle will react, for both braking and throttle.
6.13 Throttle Idle Up Throttle Idle Up is used for models that use a fuel based engine that will stall if left at 0 throttle. Idle up makes sure that the engine always has some throttle in order to keep it from stalling. This function must be assigned to a switch/button in order to be activated (See [Buttons Assign]). If not, the function cannot be activated. Setup: 1. Assign the Throttle Idle Up function to a button. For more information on this see the [Buttons Assign] section of this user manual.
6.15 Boat Mode This function is used only when you are using a model boat. When this function is active, the throttle channel is set to its lowest position and the brake functionality is disabled. To toggle this function, select the box beside [Normal mode]. When the function is active, the text beside the box will change to [Boat mode]. 6.
6.18 Display Servos This function displays the model's channel output and can be used to test output and servo range. Press the icon to start servo test mode, which will move all the channels slowly though their entire range of motion. Press the icon to turn off servo test mode. WARNING: Make sure the model engine is powered off while the test function is activated. 6.19 Race Timers Modes: • • • • Up Timer: Counts up. Down Timer: Counts down from the set time.
6.21 Models This function is used to change, reset, rename or copy model setups. The NB4 can store up to 20 different models in the internal memory. Selecting a model: To select a model touch "Select Model", then touch a model from the list. Naming a model: To rename a model touch "Name:", then use the on screen keyboard to enter a new name. Press the icon when finished to return to save and return to the previous menu. Copying a model: Touch "Copy Model", then touch the model to copy from the list.
7 RX Setup 7.1 Bind With A Receiver To bind with a reciever: 1. Put the receiver into bind mode (Check the receiver's user manual for your receiver on how to enter bind mode). 2. Touch "Bind With A Receiver" in the RX Setup menu. The NB4 will now bind with the receiver and exit automatically when binding is complete. 7.2 Failsafe This function is used to protect the models and users if the receiver loses signal and therefore is no longer controllable. Setup: 1.
8 System 8.1 Backlight Timeout The backlight timeout function controls how long the system will wait before turning off screens backlight. Setup: 1. Select a time from the list. 8.2 Backlight This function controls the backlight brightness. Setup: 1. Use the + and - icons to change the backlight percentage. 2. Touch the icon to save and return to the previous menu. 8.3 Sound This function is used to toggle all system sounds, including power-on/power-off sounds, key sounds and so on.
8.5 LED LED Light changes the color of the LED strip located above the power button. Changing Color: 1. Touch LED Light to enter the menu. 2. Select a color from the list. 3. Touch the icon to return to the previous menu. 8.6 Language Language changes the language for the user interface. Changing Language: 1. Touch "Language" to enter the menu. 2. Select a language from the list. 3. Touch the icon to return to the previous menu. 8.
8.10 Firmware Update The internal software of the transmitter can be updated using the USB interface connected via a windows computer. Once this function is activated, all functions of the transmitter stop. To avoid any loss of control of the vehicle, turn its receiver off before entering this mode. When the firmware is updating, never disconnect the USB cable or remove the battery or the transmitter. 1. Download and open the newest official software. 2. Connect a transmitter with a computer by USB cable.
