Embr Wave works like a miniature air conditioning unit: in order to deliver cool to your skin, it has to shed heat through the opposite side. As a result, when in cooling mode, Embr Wave will get warm.
The metal sides of Embr Wave may also get hot. Make sure that you aren’t covering the device when it is in use for cooling so that the heat can dissipate properly.
If your device is uncomfortably warm, turn it off for a few minutes to let it cool down. You can further accelerate the recovery process by wearing it loosely or taking it off of your wrist.
If your Embr Wave is too hot to operate, it will flash orange and red lights to indicate that the device is overheated. Overheating every now and then doesn't harm the battery, but it will if the source of heat is constant. As such, while you're not using Embr Wave, we recommend keeping it out of prolonged contact with direct sunlight.
