Review on Wireless Caregiver Personal Emergency Operating Office Electronics by Cristina Zane

It arrived very quickly and efficiently and is easy to get to work. Has 45 tones to choose from. I just picked the loudest one to wake me up when needed. His bedroom is at one end of the house and mine is at the other end of the 4 bedroom, 3 bath ranch and they are easy to get to. Has a flashing light and a sound and I use both. The battery, C2032A, I believe was already in his button, which he can wear around his neck or lay on a table. I had to buy other AAA.
