Setup and Installation

Follow these steps to install your NEWBOLER 3-in-1 Bike Computer Headlight:

1. Install the Magnet: Install the magnet between two spokes on your bicycle wheel.
2. Secure the Transmitter (Speed Sensor): Secure the speed sensor (transmitter) to the fork using a tie. Ensure the yellow line on the sensor aligns with the magnet. The magnet needs to be in the center of this sensing area.

   Focus: Make sure the distance between the emitter (sensor) and the magnet is controlled within 5mm. Rotate the emitter to adjust the distance between the two components.

   

3. Install the Base Seat: Install the screws to fix the base seat (holder) onto your handlebar.

   

4. Mount the Main Body: Push the main body (light and computer unit) into the slot of the fixed base, parallel to the front and back.

   To remove the lamp body, slightly press the end spanner and push the lamp body parallel to the front.

The bike odometer sensor connects wirelessly to the main unit, while the bike bell connects to the main body via wiring.

Operating Instructions

Headlight Operation

The headlight features three lighting modes: Strong light, Low light, and Flashing. Use the control button on the device or the wired remote to cycle through these modes.

Bike Computer Functions

The integrated bike computer displays real-time data such as speed (KMH), trip distance (TRIP DIST), and clock. It uses a sensitive sensor for accurate, satellite-independent measurements.

• Backlight Control: To switch the backlight on or off, long press the "SET" button for 5 seconds. This manual control offers more convenience than an automatic system.
• Data Display: The display shows current speed, trip distance, and time. Specific button functions (SET, MODE) are used to navigate and configure settings. Refer to the on-screen prompts for initial setup of wheel circumference and units.

Electronic Horn Operation

The electronic horn provides a loud 120dB warning. It is controlled via a wired remote, allowing you to keep your hands on the handlebars for safety.

• Sound Modes: There are 5 different sound modes available. To select your desired sound mode, press and hold the "SPK" button on the wired control for 10 seconds.

Charging

The main unit is equipped with a 2000mAh rechargeable battery and features a modern USB Type-C charging port for convenience and wider compatibility.

• Connect the provided USB Type-C charging cable to the port on the device.
• Connect the other end of the cable to a standard USB power source (e.g., computer, wall adapter).
• A charging indicator on the device will show the charging status.

Maintenance

• Cleaning: Wipe the device with a soft, damp cloth. Do not use abrasive cleaners or solvents.
• Water Resistance: The device has an IPX5 waterproof rating, meaning it is protected against low-pressure water jets from any direction. It can withstand rain but should not be submerged in water.
• Storage: Store the device in a cool, dry place when not in use. If storing for an extended period, ensure the battery is partially charged (around 50%) to prolong its lifespan.
• Sensor Battery: The speed sensor uses a CR2032 battery. Replace it when the sensor's performance degrades or the computer shows inconsistent readings.

Troubleshooting

Bike Computer Not Displaying Speed/Distance:

• Check the distance between the speed sensor (transmitter) and the magnet. It must be within 5mm. Adjust the sensor's position if necessary.
• Ensure the magnet is centered with the yellow line on the sensor.
• Verify the CR2032 battery in the speed sensor is not depleted. Replace if needed.
• Confirm the sensor is securely attached and not moving during rides.

Odometer in Sleep Mode / Not Activating Automatically:

• The bike computer is designed to detect movement from the wheel sensor. Ensure the sensor and magnet are correctly installed and aligned (within 5mm gap).
• Start cycling to activate the sensor. If it still doesn't activate, check the sensor battery and alignment again.

Headlight Not Turning On or Dim:

• Check the main unit's battery level and recharge if necessary.
• Ensure the power button is pressed correctly.

Horn Not Functioning:

• Check the wired connection of the horn control to the main unit.
• Ensure the main unit has sufficient battery power.

User Tips

• For optimal accuracy of the bike computer, ensure the speed sensor and magnet are precisely aligned and the gap is maintained at 5mm or less.
• Utilize the manual backlight control by long-pressing the "SET" button for 5 seconds, which can be more convenient than automatic modes in certain lighting conditions.
• Experiment with the 5 different horn sounds to find the one most effective for your riding environment by holding the "SPK" button for 10 seconds.
• Consider the optional floating bracket for a cleaner handlebar setup and enhanced stability.
