4. Configuració i instal·lació

4.1. Instal·lació de la bateria

The BC1200 WL uses one Lithium metal battery. If not pre-installed, open the battery compartment on the back of the computer unit and the speed sensor, insert the battery with the correct polarity, and close securely.

4.2. Mounting the Handlebar/Stem Mount

1. Choose a suitable location on your handlebar or stem that does not obstruct your view o control.
2. Place the mount on the desired position.
3. Secure the mount using the provided O-rings. Wrap the O-rings around the mount and the handlebar/stem, hooking them onto the mount's tabs. Ensure it is tight and stable.

4.3. Mounting the Speed Sensor

1. Attach the speed sensor to the front fork, on the same side as the spoke magnet will be.
2. Use the provided O-rings to secure the sensor firmly to the fork.
3. Position the sensor so that its marked area (usually a small arrow or line) aligns with the path of the spoke magnet.

4.4. Mounting the Spoke Magnet

1. Attach the spoke magnet to a spoke on your front wheel.
2. Adjust the magnet's position so that it passes the speed sensor with a gap of approximately 1-3 mm. The magnet should pass the sensor's marked area.
3. Ensure the magnet is securely fastened and will not slip during riding.

4.5. Initial Setup (Wheel Size, Language, Units)

After battery installation, the computer will prompt you for initial settings:

1. Selecció d'idioma: Use the buttons (usually 'SET' and 'MODE') to navigate and select your preferred language (e.g., English, French, German). Confirm your selection.
2. Unit Selection (KMH/MPH): Choose between kilometers per hour (KMH) and miles per hour (MPH) for speed and distance measurements.
3. Configuració de la mida de la roda: This is crucial for accurate speed and distance readings. Refer to your bicycle tire's sidewall for the ETRTO or ISO size (e.g., 23-622 for 700x23C). Consult the table below or your tire manufacturer's specifications for the corresponding circumference in millimeters (mm). Enter this value into the computer. If your exact size is not listed, measure your wheel's circumference manually by rolling the wheel one full rotation and marking the distance.
4. Configuració de l'hora: Estableix l'hora actual (format de 24 hores o 12 hores).

5. Instruccions de funcionament

5.1. Funcions sobreview

The SIGMA BC1200 WL offers 12 key functions:

• Velocitat actual: Displays your real-time speed.
• Velocitat màxima: Mostra la velocitat més alta assolida durant el trajecte actual.
• Velocitat mitjana: Calculates your average speed for the current ride.
• Distància del viatge: Measures the distance covered in the current ride.
• Distància total: Accumulates the total distance covered since the computer was reset (or first used).
• Temps de viatge: Records the duration of the current ride.
• Total Ride Time: Accumulates the total time spent riding.
• Rellotge: Mostra l'hora actual.
• Speed Comparator: An arrow indicator shows if your current speed is above or below your average speed.
• Temperatura: Mostra la temperatura ambient actual.
• Language Choice (x7): Allows selection from seven different languages.
• KMH/MPH Programming: Option to switch between metric and imperial units.

5.2. Funcions del botó

The BC1200 WL typically has two main buttons, often labeled 'MODE' and 'SET' or similar, usually located on the bottom or back of the unit.

• Botó MODE: Short press to cycle through different display functions (e.g., Trip Distance, Ride Time, Max Speed). Long press to enter or exit certain menus.
• Botó SET: Used to confirm selections, reset values, or enter setup mode. Short press for selection, long press for confirmation/reset.

5.3. Navigating Functions and Menus

A view different functions, short press the MODE button. The display will change to show the next available data point. To enter settings or reset trip data, typically a long press of the SET button is required while on a specific function display.

5.4. Restabliment de les dades del viatge

To reset trip-specific data (Trip Distance, Ride Time, Average Speed, Max Speed) for a new ride:

1. Ensure the computer is displaying one of the trip-related functions (e.g., Trip Distance).
2. Press and hold the SET button for a few seconds until the values reset to zero.
3. Note: Total Distance and Total Ride Time are cumulative and generally cannot be reset by the user.

6. Manteniment

6.1. Neteja

Clean the computer unit and sensor with a soft, damp drap. No utilitzeu productes de neteja abrasius ni dissolvents, ja que poden danyar la pantalla o laasing. The device is watertight, but avoid submerging it in water or using high-pressure water jets.

6.2. Substitució de la bateria

The battery life is approximately 2 years. When the display becomes dim or erratic, it's time to replace the battery. Open the battery compartment on the back of the computer unit (and the speed sensor if applicable), remove the old battery, and insert a new Lithium metal battery (CR2032 or equivalent) with the correct polarity. Securely close the compartment. You may need to re-enter some basic settings after battery replacement.

6.3. Emmagatzematge

When not in use for extended periods, store the computer in a cool, dry place away from direct sunlight. Removing the battery is recommended for very long storage periods to prevent leakage.

7. Solució De Problemes

• No Speed Display:
  • Check if the computer unit is correctly seated in its mount.
  • Verify the battery in both the computer and the speed sensor. Replace if necessary.
  • Ensure the speed sensor and spoke magnet are correctly aligned and the gap is 1-3 mm.
  • Check for any obstructions or damage to the sensor or magnet.
• Incorrect Speed/Distance:
  • Re-check your wheel size setting. An incorrect circumference value will lead to inaccurate readings.
  • Ensure the magnet is securely attached and not slipping on the spoke.
• La pantalla està tènue o en blanc:
  • Replace the battery in the computer unit.
  • Assegureu-vos que la bateria estigui inserida amb la polaritat correcta.
