Please rinse the watch after every workout and let it air dry before wearing again. Keep the heart rate monitor and charging port clean and clear of debris. Avoid excessive exposure to extreme temperatures and aggressive chemicals such as perfumes, sunscreen, alcohol, and cleanser.
Please recharge the watch before the battery reaches 0% to prolong the battery life.
COROS watches aren’t designed or suited for diving activities. Diving activities may damage the watch and aren’t covered by the limited warranty.
Charging port covers don't provide any waterproof capabilities. They are solely for cosmetic reasons. Please remove the covers after every workout in case water/sweat is stuck in the charging port.
