CAR LIGHT CONTROL

The car light control is mainly to implement the changeover of lighting states and lighting modes by the setting of the transmitter.
This receiver is preset with five modes for controlling model car lights. In each mode, the on/off states of backup lights are consistent; in other words, the backup light is in a high-light state when the model car backs up; otherwise, it is in off state.
The turn signal light, headlight, stop light, tail light and fog light have different on/off states as follows:

• Default mode : In this mode, the turn signal light is in off state regardless of whether the model car makes a turn or not; When braking, the stop light is in a high-light state, and otherwise, it is in off state;
  The headlight, tail light and fog light are in off state.

• Mode A : In this mode, the turn signal light is in a slow flashing state when the model car makes a turn; When braking, the stop light is in a high-light state, and when not braking, it is in a low-light state; The headlight is in a low-light state; The tail light and fog light are in off state.

• Mode B : In this mode, the turn signal light is in a slow flashing state when the model car makes a turn; When braking, the stop light is in a high-light state, and when not braking, it is in a low-light state;
  The headlight is in a high-light state; The tail light and fog light are in off state.

• Mode C : In this mode, the turn signal light is in a continuously slow flashing state regardless of whether the model car makes a turn or not; When braking, the stop light is in a high-light state, and when not braking, it is in a low-light state; The headlight is in a high-light state; The tail light and fog light are in on state.

• Mode D : In this mode, the turn signal light is in a slow flashing state when the model car makes a turn;
  When braking, the stop light is in a high-light state, and when not braking, it is in off state; The headlight is in off state; The tail light and fog light are in on state.

Notes:

1. The CH4 channel of the receiver can output both the light mode signal and the PWM signal. It needs to be set at the transmitter side. Press the CH4 button on the transmitter for a short time, the CH4 channel outputs the light mode. Each time it is pressed,one mode per press (Default Mode, Mode A, Mode B, Mode C and Mode D are switched in turn); Press and hold the CH4 button for a while,then switch the CH4 channel to PWM output.
2. Every time the receiver is turned on, the car light control mode is in Default Mode.
3. Mode C is an emergency light working state. In this mode, the left and right turn signal lights flash synchronously and slowly as emergency lights.
4. This receiver identifies the neutral positions of Steering CH1 and Throttle CH2 automatically when it is powered on. It recommends to power on the receiver again after the trims of the transmitter are turned.

CHARGING THE BATTERY

1. Connect the charger to a USB port then connect the battery to the charger.
2. When charging, the status LED is red, when charged, the status LED is green.
3. Do not let the battery charge unattended!
4. If the battery or charger is hot, disconnect the battery and charger immediately as this may be caused by an internal short-circuit.

ESC FUNCTION INSTRUCTIONS

1. Connect related equipment
   • Make sure the ESC is off before connection. Connect the motor with M+ and M- of ESC. Connect the steering servo to the 3Pin interface marked with «ST» of ESC (- + S connected correspondingly).
   Connect the battery with the positive and negative poles of ESC correspondingly.

2. Normal boot, identification throttle midpoint:
   • After connecting related equipment as step 1, turn on the radio first, move the throttle trigger to the neutral position. Turn on the switch of ESC at last. The receiver will automatically recognize the battery type when it is powered on again. Then it can run it.

Notes:
a. The ESC can be run after completing self-inspection (about 3 seconds) if power on, otherwise it cannot be operated normally.
b. If there is no power output and the red light of ESC flashes quickly after power on, please check whether the throttle trim of the transmitter is set to the «0» position, the receiver will automatically recognize the midpoint of the trim throttle after restarting;
c. If the rotation direction is not correct during running, exchange the two wires connecting motor and ESC.
d. To make sure everything is ok, please turn on the transmitter first and finally turn on the ESC, turn off the ESC first and finally turn off the transmitter.
Note: Please refer to the relevant sections for details about the battery type, drag brake force and running mode of the ESC.

Attention:

• Make sure the product is installed and calibrated correctly, failure to do so may result in serious injury.
• Please carefully check each power device and car frame instructions to ensure the power matching is reasonable before use. Avoid damaging power system due to incorrect matching.
• Do not let the external temperature of the system exceed 90°C /194°F , because high temperature will damage the power system.
• Make sure the receiver’s battery is disconnected before turning off the transmitter, failure to do so can result out of control. Unreasonable setting of the Failsafe may cause accidents.
• After use, remember to disconnect the battery and the ESC. If the battery isn’t disconnected, the ESC will consume electric energy all the time even if it is off. It will discharge completely if connect the battery for a long time, thus resulting in the failure of the battery or the ESC. We are not responsible for any damage caused by this!
• Make sure the receiver is mounted away from motors or any device that emits excessive electrical noise.
• Keep the antenna of the receiver at least 1cm away from conductive materials such as carbon or metal.
• Do not power on the receiver during the setup process to prevent loss of control.
