2. Getting Started (Setup)
2.1 Components
The package includes:

- CR2032 Battery (pre-installed or included)
2.2 Wearing the Heart Rate Monitor
For accurate readings, ensure the heart rate monitor is worn correctly:
- Moisten the two electrode pads on the back of the strap with water or electrode gel. This improves conductivity.
- Attach the sensor module to the chest strap using the two snap buttons. Ensure the EZON logo is facing upwards.

4. Maintenance
4.1 Cleaning the Chest Strap
To maintain hygiene and ensure optimal performance, clean the chest strap regularly:
- Detach the sensor module from the chest strap by unsnapping the buttons.
- Hand wash the fabric strap with mild soap and water. Do not machine wash or tumble dry.
- Rinse thoroughly to remove all soap residue.
- Hang the strap to air dry completely before reattaching the sensor or storing.
- Wipe the sensor module with a damp cloth and dry it thoroughly. Do not submerge the sensor module in water for cleaning, as it is only water-resistant, not fully waterproof when detached.

4.2 Battery Replacement
The C009Pro uses a replaceable CR2032 coin cell battery, offering up to 365 days of use. When the battery is low, your connected app may indicate a weak signal or the device may stop transmitting data.
- Use a small coin to twist open the battery cover on the back of the sensor module.
- Remove the old CR2032 battery.
- Insert a new CR2032 battery with the positive (+) side facing upwards.
- Replace the battery cover and twist it securely to ensure a watertight seal.

5. Troubleshooting

- Verify that Bluetooth/ANT+ is enabled on your receiving device and the sensor is paired correctly within the app.
- Replace the CR2032 battery if it's low or depleted.
- Inaccurate Readings:
- Ensure the strap is snug but comfortable. A loose strap can cause erratic readings.
