Installation Instructions

Battery Installation

To install or replace the battery, use a coin to turn the battery cover counter-clockwise. Insert a CR2032 battery with the positive electrode (+) facing the cover. All previously recorded data will be reset upon battery replacement.

Bracket Installation

Attach the bracket to the bicycle handlebar using the provided rubber slice and ribbon cord.

Transmitter Installation

Secure the transmitter to the bicycle tube with the rubber slices and ribbon cord. Ensure the side marked "SENSOR" faces forward towards the magnet. The maximum distance between the bicycle computer and the transmitter should be 80cm.

Magnet Installation

Disassemble the nut from the magnet's bottom, then fasten the magnet with a screw to the spokes of the wheel and tighten the nut. The minimum distance between the transmitter and magnet should be less than 5mm. The transmitter and gauge unit should be placed vertically, with an angle not exceeding 30 degrees.

Operation Instruction

System Initialization Parameter Setting

All stored information will reset to zero when the battery is replaced. Parameters must be set for accurate riding data. To enter the system initialization parameter setting, either replace the battery or, in CLOCK MODE, press and hold the [MODE] button for 2 seconds.

Configurable Parameters:

• Speed unit (KM/H or MPH)
• Wheel circumference
• Total riding time
• Total riding distance
• Date
• Height
• Weight
• Age
• Language (English, Deutsch, French, Espanol, Italian)

A table of common wheel diameters and their corresponding set values in millimeters is provided to assist with circumference setting. To measure wheel circumference: 1) Refer to the provided table for perimeter set values based on wheel size. 2) Mark a point on the wheel, push the bike for one full rotation, and measure the distance in millimeters, which represents the wheel circumference.

EL Backlight Operation

In any mode, hold [SET] + [MODE] simultaneously for 3 seconds to toggle the backlight ON or OFF. When ON, the backlight remains active for 3 seconds.

Function Display Modes

Press the [MODE] key to cycle through different display modes. These include:

• CLOCK: Displays current time (12H or 24H format).
• STOPWATCH: Starts/stops with a single [SET] press; hold [SET] for 2 seconds to reset.
• TRIP DIST: Current trip distance, which can be cleared.
• RIDE TIME: Current riding time, which can be cleared.
• AVG SPEED: Average cycling speed for the current trip, which can be cleared.
• MAX SPEED: Maximum speed reached for the current trip, which can be cleared.
• TRIP UP/DOWN: Allows setting a target value. Switch to TRIP UP/DOWN mode with [MODE], hold [SET] for 3 seconds to enter setting. Press [SET] to select UP or DOWN, [MODE] to change digits, and [SET] for 3 seconds to exit.
• CALORIE: Calorie consumption measured in KCAL.
• TOT DIST: Records total accumulated mileage. This value can be reset, and will reset if the battery is replaced.
• TOT TIME: Records total accumulated cycling time. This value can be reset, and will reset if the battery is replaced.
• SCAN: Automatically cycles through RIDE DIST, RIDE TIME, AVG SPEED, and MAX SPEED every 4 seconds.

Memory Function

In MEMORY mode, pressing [SET] displays daily riding data, including date, distance, riding time, maximum speed, and average speed. Users can view data for up to seven days. Data stored in memory cannot be cleared manually. Daily cycling data is automatically saved at 12:00 AM.

Data Clearing

To clear current ride data (RIDE DIST, RIDE TIME, MAX SPEED, AVG SPEED), hold the [SET] key for 3 seconds until "RESET" flashes three times. This action resets the current mode's cycling data but does not affect total mileage (TOT-DIST), total time (TOT-TIME), or MEMORY data.

Automatic Shutdown/Boot

The computer enters a dormant state after 4 minutes of no speed signal. It automatically turns on when any key ([MODE] or [SET]) is pressed or when vibration is detected during riding.

Energy Saving

To conserve battery power, the device enters dormancy standby after 4 minutes of no speed signal. It will automatically boot when any button is pressed or riding commences.

Important Notes

• The bicycle computer is designed for use on rainy days but is not waterproof and should not be used underwater.
• Avoid prolonged direct sunlight exposure when the computer is not in use.
• Regularly check the distance between the speed sensor and the magnet.
• Do not use alcohol, thinner, or other organic solvents to clean the computer or its accessories.
• Always pay attention to road conditions to ensure safety.

Troubleshooting
