Why did the alert go off when I had no symptoms?


The alert is triggered to prevent heat stroke so you may not yet feel any symptoms at the time of the alert.
According to feedback that has been received, 70% of the alerts are triggered before any symptoms appear.
In such situations, even if you are not aware of it, your core body temperature may continue to rise. It’s therefore important to hydrate, take a break, and check your physical condition before continuing your activity.


Is it possible to change the volume and sound of the alert?


Changing the volume or sound of the alert is not possible. The alert is set to a volume and range that is easy for the human ear to hear, even outdoors or in noisy environments.


Can the product be used in a hot environment?


The product can be used in environments where the temperature is above 40°C.
It can be used up to an ambient temperature near the wrist of 80°C.
