4. Setup

4.1 Mounting the Computer and Cadence Sensor

Use the provided computer mount to securely attach the device to your bicycle handlebars. The cadence sensor should be installed on the crank arm. Ensure both are firmly in place to prevent movement during rides.

4.2 Initial Power On and Basic Settings

1. Press and hold the left button to power on the device.
2. Upon first use, you may need to configure basic settings such as time zone and measurement units (e.g., kilometers or miles). Refer to the on-screen prompts or the device's menu for navigation. Setting the correct time zone is crucial for the automatic backlight adjustment system to function accurately.

4.3 Sensor Pairing (ANT+ and Bluetooth)

The ROCKBROS BC supports external sensors via ANT+ and Bluetooth for enhanced data collection (e.g., heart rate monitors, power meters, speed sensors). To pair a sensor:

1. Ensure the external sensor is active and within range of the bicycle computer.
2. Navigate to the device's sensor pairing menu.
3. Select the type of sensor you wish to pair (e.g., cadence, heart rate, power).
4. The computer will search for available sensors. Select your sensor from the list to complete pairing.

4.4 Tire Circumference Setting

For accurate distance tracking, especially when not relying solely on GPS, it is recommended to set your tire's circumference in millimeters (MM). This setting is typically found in the device's system or calibration menu. Consult your tire's specifications or measure it directly for the most precise value.

5. Operation

5.1 Power On/Off

• Power On: Press and hold the left button.
• Power Off: Press and hold the left button for several seconds until the device powers down.

5.2 Starting and Stopping a Ride

• After powering on, press the left button again to begin recording your ride data. The trip time will start counting.
• To pause or stop recording, press the left button.

5.3 Display Navigation

The right button allows you to cycle through different display pages, each presenting various aspects of your current ride, average data, or maximum values.

5.4 GPS Functionality

The device uses multiple satellite systems for precise positioning. For optimal performance, ensure the device has a clear view of the sky and avoid moving it during the initial positioning phase.

This image highlights the bicycle computer's dynamic positioning system, showing icons for GPS, GLONASS, BDS (Beidou), and Galileo satellites, indicating its multi-system support for accurate tracking.

5.5 Data Display Customization

You can customize up to 5 data display pages, with each page capable of showing a maximum of 7 data elements. This allows you to prioritize the metrics most important to your ride. Refer to the device's settings menu to configure your preferred data layouts.

• Storage: Store the computer in a cool, dry place when not in use. Avoid extreme temperatures.

8. Troubleshooting

• GPS Connectivity Issues: If the device takes a long time to connect to GPS or shows inaccurate readings, ensure you are in an open area with a clear view of the sky. Avoid moving the device during the initial GPS lock.
• Inaccurate Speed/Distance: Verify that the tire circumference setting is correctly entered in the device's settings. Ensure the cadence sensor is properly installed and paired.
• Backlight Not Adjusting Automatically: Check that the correct time zone is set on the device. The automatic backlight system relies on accurate time zone information.
• Sensor Not Pairing: Ensure the sensor is active, has sufficient battery, and is within range. Try restarting both the computer and the sensor.
