CarePredict Tempos are rated IP67, meaning they are 100% protected against solid objects like dust and sand, and they have been tested to work for at least 30 minutes while under 15cm to 1m of water.
If however, there is any damage to the Tempo or erosion of the adhesive (caused by soapy water) then this could allow water intrusion and lead to the Tempo malfunctioning. If a Tempo is looked after properly, there should be no problem wearing it in the pool for swimming or water aerobics.
If your Tempo stops working after getting wet, please check to make sure the glass panel is still on the bottom of the Tempo, covering the heart rate monitor. And then make sure the Tempo is completely dried by removing the battery and leaving the Tempo and battery both out to air dry for an hour or more. It should start working again unless there has been water intrusion. You may see evidence of water intrusion if the glass piece covering the heart monitor fell off, which could be a result of increased pressure if the Tempo was submerged over 1 meter. Since we do not collect any data for swimming, we recommend residents remove their Tempos and leave them by the pool while they swim.
