Product description

7. Sealed compartment (you can place your own lifebuoy inside before traveling: write your name, address, phone number, blood type, etc. so that rescue personnel can grasp your situation in the first time)

[Battery replacement method] Open the thing and look inside the middle mirror, which is behind the LED light. There is a screw that is the place to replace the button battery.
