Waterproof
I learned during a power outage that the unit that I had did not switch to the battery because my unit required electricity to activate the land line unit. I tried a unit that did not relied on a celluar coverage, AT&T which drops calls in my area. I went back to the previous unit which has worked well but I now know that it won’t work in a power outage. It is the only pendant that can be submerged in water and still work. Big difference between water resistant and waterproof. Only company I found that is waterproof.
