The CatEye Velo Wireless Cyclocomputer (CC-VT230W) is a bicycle computer designed to track and display various cycling metrics wirelessly. It comprises a main computer unit, a speed sensor, a magnet, a bracket, and mounting accessories.

Function Description

The primary function of the CC-VT230W is to provide real-time and cumulative data related to your bicycle ride. It displays current speed, average speed, maximum speed, trip distance, total distance, elapsed time, calorie consumption, and a clock. The device uses a wireless speed sensor that attaches to the bicycle fork, and a magnet that attaches to a spoke, to measure wheel rotations and calculate speed and distance.

The computer features a clear LCD screen that shows one main measurement at the bottom, which can be cycled through using the MODE button. A smaller display at the top continuously shows the current speed. A "sensor signal icon" flashes in sync with the sensor signal, indicating proper communication. A "pace arrow" indicates whether the current speed is faster or slower than the average speed, providing immediate feedback on your performance.

The device automatically starts measurement when the bicycle moves and stops when it is stationary. During measurement, the measurement unit (km/h or mph) flashes. All measurement data, except for the total distance (Odo), can be reset to zero by pressing and holding the MODE button on the measurement screen.

For power saving, if the computer does not receive any signal for 10 minutes, it enters a power-saving screen, displaying only the clock. If left in this state for 1 hour, it will display "SLEEP." The computer returns to the measurement screen if the MODE button is pressed or a sensor signal is received.

Usage Features

Mounting the Computer:

The installation process involves several steps to ensure accurate data collection. First, the bracket is mounted on either the stem or the handlebar. When mounting on the handlebar, it's crucial to adjust the bracket's angle so the back of the computer faces the speed sensor when attached. Next, the speed sensor is mounted on the right or left front fork. The sensor must be positioned so that the distance from the computer to the speed sensor is within the signal range (maximum 70 cm or 27 inches). Finally, the magnet is mounted on a spoke. The magnet must pass through the speed sensor zone, and the clearance between the speed sensor and the magnet should be within 5 mm (3/16 inches). After all components are mounted, the computer unit is attached to the bracket by clicking it into place. A test operation is recommended: rotate the front wheel gently to check if the current speed is displayed. If not, recheck the attachment conditions.

Setting Up the Computer:

Before initial use or after a factory reset, the computer needs to be set up. This begins by clearing all data by pressing the AC button on the back of the computer. Then, the measurement unit (km/h or mph) is selected. The tire size is a critical setting for accurate speed and distance calculations. Users can choose a simple setting method by selecting a predefined tire size in inches (e.g., 26”, 700C, 27.5”) or an advanced setting method by manually entering the tire circumference in centimeters (from 100 to 299 cm). The clock is then set, allowing selection between 24-hour or 12-hour display modes and adjusting hours and minutes. Once all settings are confirmed by pressing the MENU button, the setup is complete, and the computer switches to the measurement screen.

Changing Settings (Menu Screen):

From the measurement screen, pressing the MENU button accesses the menu screen, where various settings can be adjusted. These include tire size selection, clock settings, manual distance input, and measurement unit selection.

Tire Size Selection: Allows users to re-select the tire size using either the simple or advanced method.
Clock: Enables adjustment of the time and selection of the 12h or 24h display format.
Manual Distance Input: This feature allows users to manually input a total distance traveled (0 - 99999 km/miles). This is particularly useful when replacing the computer battery or purchasing a new bicycle, enabling continuity from a previous total distance value.
Select Measurement Unit: Allows switching between kilometers per hour (km/h) and miles per hour (mph). After any changes in the menu, it is essential to press MENU to confirm the adjustments. If the menu screen is left inactive for one minute, the computer automatically returns to the measurement screen.

Maintenance Features

Cleaning:

For general maintenance, if the computer or its accessories become dirty, they should be cleaned with a soft cloth moistened with mild soap. Avoid using thinners, benzine, or alcohol, as these can damage the device.

Replacing the Battery:

Both the computer unit and the speed sensor use CR2032 lithium batteries.

Computer Battery: When the display becomes dim, it's an indication to replace the computer battery. A new CR2032 battery should be inserted with the (+) side up. After replacement, the computer setup procedure (including clearing data and re-entering settings like tire size and clock) must be followed. It's recommended to note the total distance value before battery replacement to re-enter it later.
Speed Sensor Battery: If the speed is not displayed correctly even after adjusting the sensor and magnet positions, the speed sensor battery may need replacement. A new CR2032 battery should be inserted with the (+) side up, and the battery cover closed firmly. After replacement, the magnet's position relative to the speed sensor should be re-adjusted as described in the mounting instructions.

Troubleshooting:

The manual provides guidance for common issues:

Sensor Signal Reception Icon Not Flashing (Speed Not Displayed): This often indicates issues with the speed sensor and magnet. Users should check if the clearance between the speed sensor and magnet is within 5 mm (3/16 inches), if the magnet passes through the sensor zone correctly, if the computer is mounted at the correct angle (facing the speed sensor), and if the computer and speed sensor are within the correct distance apart (20 to 70 cm or 8 to 27 inches). If these conditions are met, a flat computer or speed sensor battery might be the cause, as battery performance can diminish in winter. Weak batteries can also cause the computer to react only when very close to the speed sensor. In such cases, replacing the batteries is recommended.
Display Remains Blank When Button is Pressed: This typically points to a flat computer battery, requiring replacement.
Incorrect Data Appear: If incorrect data are displayed, all data should be cleared by following the procedure for setting up the computer.

The device is designed for safe use, emphasizing that users should not concentrate on the computer while riding and should always ride safely. It also advises against disassembling the computer or leaving it in direct sunlight for extended periods.
