This Uniden Emergency Alert Pendant works in conjunction with your existing Uniden cordless phone system so you can easily call for help in case of an emergency. You can set it up to call 5 different numbers of your choice, one at a time until someone answers, allowing you to let someone know you need help. The pendant comes with a belt clip, wrist band and neck strap, allowing you to keep it nearby in a way that's comfortable for you.
