Keep Your Gadgets Totally Safe From Water:-

You already have known about the ATM rating. Now from my concern, some safety points for keeping your devices safe within and without water are as follows –

  • For any kind of reason, if you submerge your smartwatch into the water then in that time don’t press any buttons.
  • The ATM rating for wearable gadgets is only for Normal water resistance not for seawater or any other liquids like soft drinks and something else. So it is safe to use your device in normal water. Don’t use it in the sea or water something like that.
  • As I said in the last point that liquid ingress in ATM rating does not mean any types of liquids. Only normal water is suggested. So if your fitness tracker sinks into other liquids then it may damage your device as it can’t endure.
  • Another and last safety point is that every ATM rating is different from each other. 5 ATM is not 10 ATM obviously and also 10 ATM is not 20 ATM. So, suppose, if your device has 5 ATM that doesn’t mean that it can endure everything that endures 20 ATM. Therefore, make sure what ATM rating your gadget has and use it accordingly and also safely.
