3. Setup and Installation

3.1. Battery Installation

The M-Wave M14w computer and its wireless sensor require CR2032 batteries. Batteries are included with the product. If not pre-installed, carefully open the battery compartment on the back of the computer unit and the sensor, insert the CR2032 battery with the positive (+) side facing up, and securely close the compartment.

3.2. Mounting the Computer Unit

The computer unit can be mounted on your bicycle's handlebar or stem without the need for any tools.

1. Place the mounting bracket on your desired location on the handlebar or stem.
2. Secure the bracket firmly using the provided zip ties or straps, ensuring it is stable and does not rotate.
3. Slide the M14w computer unit onto the mounting bracket until it clicks securely into place.

3.3. Installing the Speed Sensor and Magnet

The wireless speed sensor and wheel magnet work together to measure your speed and distance.

1. Attach the wireless speed sensor to the front fork of your bicycle using the provided zip ties or straps. Position it on the side where the wheel magnet will be installed.
2. Attach the wheel magnet to a spoke on the front wheel.
3. Adjust the position of both the sensor and the magnet so that they are aligned and the gap between them is approximately 1-3mm when the wheel rotates. The magnet should pass directly in front of the sensor's marked detection area.

3.4. Initial Configuration

After installation, you will need to configure the computer for accurate readings.

1. Power On: The device will automatically power on when motion is detected or a button is pressed.
2. Unit Selection: Press the "Mode" button to cycle through settings. Use the "Set" button to select between Metric (km/h) and English (mph) units.
3. Wheel Size Setting: This is crucial for accurate speed and distance measurements. Refer to your bicycle tire's sidewall for its circumference in millimeters (e.g., 2070mm for a 700x23c tire). Use the "Set" and "Mode" buttons to input this value into the computer.
4. Clock Setting: Set the current time using the "Set" and "Mode" buttons.
5. Pairing (if necessary): The computer and sensor should automatically pair. If not, consult the troubleshooting section or perform a manual pairing sequence (often involves holding a button on the sensor or computer during initial setup).

4. Operating Instructions

The M-Wave M14w features two primary buttons: "Set" and "Mode", located at the bottom of the display.

4.1. Navigating Modes

Press the Mode button to cycle through the various display functions. The M14w typically displays:

• Current Speed (SPD): Your real-time riding speed.
• Average Speed (AVS): Your average speed for the current trip.
• Maximum Speed (MXS): The highest speed recorded during the current trip.
• Trip Distance (DST): The distance covered during the current trip.
• Total Distance (ODO): The cumulative distance covered since the computer was reset or first used.
• Riding Time (TM): The duration of your current ride.
• Clock (CLK): Current time.
• Scan Mode: Automatically cycles through various functions.

4.2. Adjusting Settings and Resetting Data

To adjust settings or reset trip data:

• Entering Settings: In clock mode, press and hold the Set button to enter the setting menu (e.g., for wheel size, unit selection). Use Mode to change values and Set to confirm and move to the next setting.
• Resetting Trip Data: To clear current trip data (DST, AVS, MXS, TM), navigate to any of these modes and press and hold the Set button until the values reset to zero. The Total Distance (ODO) cannot be reset through this method.

4.3. Auto Power On/Off

The M14w features an automatic power-saving function. The device will automatically power on when it detects movement from the wheel sensor or when any button is pressed. It will power off after a period of inactivity to conserve battery life.

5. Maintenance

Proper maintenance ensures the longevity and accuracy of your M-Wave M14w bicycle computer.

• Cleaning: Wipe the computer unit and sensor with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these can damage the display or casing.
• Water Resistance: The M14w has an IP44 rating, meaning it is protected against splashing water from any direction. While it can withstand light rain, avoid submerging the device in water or exposing it to high-pressure water jets.
• Battery Replacement: When the display becomes dim or erratic, it's time to replace the CR2032 batteries in both the computer and the sensor. Ensure correct polarity when inserting new batteries.
• Sensor and Magnet Alignment: Periodically check that the speed sensor and wheel magnet remain properly aligned (1-3mm gap) and securely fastened. Vibrations from riding can sometimes cause them to shift.
• Storage: If storing the bicycle computer for an extended period, it is recommended to remove the batteries to prevent leakage and potential damage to the device.

6. Troubleshooting

If you encounter issues with your M-Wave M14w, try the following troubleshooting steps:

• No Display / Dim Display:
  • Check if batteries are correctly installed.
  • Replace batteries in both the computer unit and the sensor.
• No Speed/Distance Reading:
  • Ensure the wheel magnet and speed sensor are properly aligned and the gap is within 1-3mm.
  • Check if the sensor battery is dead or low. Replace if necessary.
  • Verify that the computer and sensor are paired. If not, try re-pairing by removing and reinserting the computer battery, then spinning the wheel to activate the sensor.
  • Ensure the computer is securely seated in its mounting bracket.
• Inaccurate Readings:
  • Double-check the wheel circumference setting. An incorrect value will lead to inaccurate speed and distance.
  • Ensure the sensor and magnet are not obstructed by dirt or debris.
  • Interference from other wireless devices or strong electromagnetic fields can sometimes affect readings. Try moving away from such sources.
• Difficulty Setting / Sporadic Operation (as per user feedback):
  • If the device is difficult to set or operates sporadically, try a full reset. This often involves removing the battery for a few minutes, then reinserting it. Be aware that this will clear all settings and trip data, requiring re-configuration of wheel size and time.
  • Ensure buttons are not stuck or dirty.
• Computer Not Powering On Automatically:
  • Ensure the sensor is active and transmitting. Spin the wheel to check.
  • Check sensor battery.
