This wireless water resistant device is designed to mount on a wall.
Mount one next to the bed-side table or even next to the shower in
the bathroom. These permanent communicators allow for full two-way
voice communication anytime an emergency occurs. These units are
particularly handy if one forgets to carry their pendant with them
to the bathroom in the middle of the night. They operate in standby
for well over a year on 4AAA alkaline batteries...and provide over 5
hours of talk time.
