3. Persediaan dan Pemasangan
The CYCPLUS C3 sensor can function as either a speed sensor or a cadence sensor. The mode is selected by rotating the battery cover. A blue light indicates speed mode, and a green light indicates cadence mode.
3.1. Pemilihan Mod
- Open the battery cover by gently prying it open or rotating it counter-clockwise if it's a twist-lock design.
- Observe the internal switch or indicator.
- Untuk memilih Mod Kelajuan, ensure the internal switch is aligned with the 'S' marking or rotate the cover until the blue light flashes upon activation.
- Untuk memilih Mod Irama, ensure the internal switch is aligned with the 'C' marking or rotate the cover until the green light flashes upon activation.
- Tutup penutup bateri dengan selamat.
3.2. Installation as Speed Sensor
- Ensure the sensor is in Speed Mode (blue light).
- Attach the sensor to the wheel hub using the provided elastic band. For curved hubs, use the curved rubber mat between the sensor and the hub for a secure fit.
- Ensure the sensor is firmly attached and does not interfere with wheel rotation.
3.3. Installation as Cadence Sensor
- Ensure the sensor is in Cadence Mode (green light).
- Attach the sensor to the inside of the crank arm using the provided elastic band. For flat crank arms, use the flat rubber mat between the sensor and the crank for a secure fit.
- Ensure the sensor is firmly attached and does not interfere with pedaling.

5. Penyelenggaraan
5.1. Penggantian Bateri
The sensor uses a CR2032 button cell battery. When the indicator light no longer flashes or the sensor fails to connect, it's time to replace the battery.
- Locate the battery cover on the back of the sensor.
- Use a coin or a small flat tool to gently pry open or twist the battery cover counter-clockwise until it can be removed.
- Keluarkan bateri CR2032 lama.
- Masukkan bateri CR2032 baharu dengan bahagian positif (+) menghadap ke atas.
- Replace the battery cover, ensuring it is securely closed to maintain waterproofing.

5.2. Pembersihan
Lap sensor dengan lembut, damp cloth as needed. Do not use abrasive cleaners or solvents, as they may damage the device.
6. Penyelesaian masalah
- Sensor tidak diaktifkan: Ensure the sensor is properly installed and motion (wheel or crank rotation) is sufficient to wake it up. Check battery level.
- Tidak boleh berpasangan dengan peranti:
- Ensure the sensor is active and within range of your device.
- Check if Bluetooth/ANT+ is enabled on your device.
- Verify the sensor is in the correct mode (speed or cadence) for the data you are trying to receive.
- Restart both the sensor (by removing and reinserting the battery) and your receiving device.
- Note: The Bluetooth of this product can only be applied to corresponding fitness apps (e.g., Zwift) and cannot be directly connected to a mobile phone's general Bluetooth settings due to protocol differences.
- Bacaan tidak tepat: Ensure the sensor is securely mounted and not shifting during use. Check for any obstructions.
- Sambungan terputus-putus: Ensure there are no strong electromagnetic interferences nearby. Check battery level.
