Cautionary Notes For the Binoculars (1) Never look at the sun or a bright light with the binoculars. Doing so can cause loss of vision. (2) The binoculars are water-resistant enough for use in the rain. However, they are not for underwater use. (3) If the binoculars are taken from a cold environment to a warm one, condensation may develop on the surface and internal parts. To prevent condensation, first put the binoculars into an airtight plastic bag before taking it to a warm environment.
