1. Sensor failure: The heart rate monitoring sensor on the rowing machine may be out of order, which makes it impossible to detect the heart rate normally. It is recommended to check whether the sensor is blocked or damaged by sundries. If there is any problem, you can contact the after-sales service for repair or replacement.
2. Incorrect wearing position: The heart rate monitoring sensor is usually located on the handle of the rowing machine. If you hold your hand incorrectly, it may lead to inaccurate heart rate monitoring. It is recommended to place the hand on the handle correctly and ensure that the hand fits completely.
3. Software settings: Sometimes, heart rate monitoring may require specific settings in devices or applications to ensure normal work. It is recommended to check the settings in Huawei Health Application to see if it is necessary to turn on the heart rate monitoring function.
