The binoculars are waterproof. To make full use of this performance,
make sure to check the O-ring in the battery chamber and the contact
surface. If you close the battery chamber cover when it is covered
with sand, hair or other materials, the waterproof property will be lost,
allowing water to enter, resulting in malfunction.
Check the O-ring.
