Safety Warnings and Product Information
Warnings
Failure to notice the potential dangers listed below may lead to severe harm or even fatal accidents.
Battery-related warnings
The product uses a CR2032 button cell. Failure to follow the instructions listed below may shorten the battery's shelf life, damage the device, or cause fire, chemical burns, battery leakage, or the risk of injury.
- Do not disassemble, modify, puncture, or damage the device or the battery.
- Do not expose the device or the battery to fire, explosion, or other hazards.
- Do not place or store the device near a dryer, in a car under direct sunlight, or in other high-temperature environments.
- Do not immerse the battery in water or other liquids.
- Do not use any sharp object when removing the button cell.
- Keep the battery out of reach of children. Swallowing the battery may cause chemical burns, soft tissue perforation, or even death. Seek immediate medical help if the battery is swallowed.
Product Introduction
The Magene S314 supports standard Bluetooth and ANT+ protocols. When installed properly on the crank or hub, it accurately measures your cadence or speed. The S314 allows for scientific and pleasant training when installed on a device supporting standard Bluetooth and ANT+ protocols, such as bike computers, sports watches, and cycling apps.
With the battery installed, the sensor is in speed mode if the green indicator blinks and in cadence mode if the red indicator blinks.

Sensor Installation
Notes:
- The sensor can be switched between speed and cadence modes by reinstalling the battery or using the Magene Utility app. The sensor can only be in one mode at a time.
- Use the silicone pad or silicone ring as required by actual conditions.
- To prevent the sensor from being damaged or lost after falling off, ensure that the sensor and the silicone ring do not rub against your shoes and bike during use.
Speed Mode
With the battery installed, the sensor is in speed mode if the green indicator blinks. Install the silicone pad at the bottom of the sensor and use the silicone ring to install the sensor on the front hub. Rotate the wheel and search the sensor using a device supporting the Bluetooth or ANT+ protocol.

With the battery installed, the sensor is in cadence mode if the red indicator blinks. Install the silicone pad at the bottom of the sensor and use the silicone ring to install the sensor on the internal side of the left crank. Rotate the crank and search the sensor using a device supporting the Bluetooth or ANT+ protocol.

| Indicator | Device Status |
|---|---|
| Green indicator blinks | Speed Mode |
| Red indicator blinks | Cadence Mode |
| Red and green indicators blink alternately | Low battery |
The sensor broadcasts via Bluetooth or ANT+ only after correct installation and use. You can then search and connect using a compatible device or app.
- Bluetooth Protocol: Connects to only one device or app at a time. Disconnect first to switch devices/apps.
- Mobile App Connection: Search and connect the sensor within the app. System Bluetooth search/connect is not supported.
- ANT+ Protocol: Can connect to multiple devices simultaneously.
- Sleep Mode: The sensor automatically enters sleep mode after 60 seconds of inactivity to reduce power consumption.
Battery Replacement
Follow these steps to replace the battery:
Step 1: Rotate the position mark on the battery cover counter-clockwise from the locked position to the open position to open the battery compartment.

The instruction is to rotate the mark counter-clockwise from the locked position to the open position to access the battery compartment.Step 2: Place a new battery into the battery holder. Align the position mark on the battery cover with the open position and press the cover down. After ensuring the cover is fully pressed, rotate the mark clockwise to the locked position.

- Why cannot I search and find my new sensor?
Answer: Check if a battery is installed. Verify app compatibility. Reinstall the battery to check indicator lights. If issues persist, contact after-sales technical support.
- Why cannot I search and find the sensor after having used it for a time?
Answer: To reduce power consumption and extend service time, the sensor enters sleep mode after 60 seconds of inactivity. It will automatically wake up and transmit data when you start cycling again.
- Why does the indicator not go on after I reinstall the battery?
Answer: This may be due to the capacitor's energy storage effect; try reinstalling the battery after a 10-second delay. Ensure the electrode clip in the battery holder is properly seated; lift it if it's not springing back, indicating poor contact. The battery may also be dead; replace it with a new CR2032 (3V) battery. If problems persist, contact after-sales technical support.
- Does the sensor have the data calculation latency issue?
Answer: The sensor uses a geomagnetic sensor for data measurement, unlike traditional systems using a reed switch and magnet. This simplifies installation but can introduce a degree of latency in data calculation.
- Why does the sensor run out of battery in a short time?
Answer: The sensor typically operates for 500 hours (actual hours may vary based on environment). Avoid installing the sensor if it is not in use, as it will frequently wake up and accelerate power consumption. If issues persist, contact after-sales technical support.
