Swimming with my A300
A300 is suitable for swimming and it is water resistant. When swimming, it is recommended to use a Polar H7/H10 heart rate sensor. In water, H7/H10 sends the heart rate at the GymLink frequency to A300. The sensor's other frequency, Bluetooth® Smart, is used for other sports when H7/H10 is paired with your A300.
When measuring heart rate in water, you may experience interference because:
- The ECG signal strength is individual and may vary depending on the individual’s tissue composition. Problems occur more frequently when measuring heart rate in water.
- Pool water with high chlorine content and seawater are very conductive. Sensor electrodes can short-circuit in these conditions preventing ECG signal detection.
- Jumping into water or strenuous muscle movement during competitive swimming may shift the sensor on your body where ECG signals aren't detected.
It is essential that you wash the device and the wristband if you wear them in a swimming pool where chlorine is used for keeping the pool clean. Wash the device and the silicone wristband after each training session under running water with a mild soap and water solution. Please remove the device from the wristband and wash them separately. Wipe them dry with a soft towel. Don't charge the device when it is wet.
