3.3 Wearing the Chest Strap
- Moisten Electrodes: Lightly moisten the electrode areas on the back of the chest strap with water or conductive gel. This ensures good contact with your skin.
- Position the Strap: Place the chest strap directly against your skin, just below your pectoral muscles. The EZON logo should be facing forward.
- Adjust Fit: Adjust the strap length to ensure a snug but comfortable fit. It should not be too loose, as this can affect heart rate detection.
- Pairing: The watch should automatically detect the chest strap when it's worn correctly and within range. Look for a heart rate icon or reading on the watch display.

5. Maintenance
5.1 Watch Battery Replacement
The watch uses a standard coin cell battery (e.g., CR2032). When the display dims or functions become erratic, it's time to replace the battery.

- Gently pry open the back cover.
- Remove the old battery, noting its orientation (+/-).
- Insert a new battery with the correct orientation.

5.2 Chest Strap Battery Replacement
The chest strap also uses a coin cell battery (e.g., CR2032).
- Locate the battery compartment on the chest strap transmitter. It usually has a twist-off cover or small screws.
- Open the compartment and remove the old battery.
- Insert a new CR2032 battery with the positive (+) side facing up.
- Close the compartment securely, ensuring the seal is intact for water resistance.
5.3 Cleaning
