A medical alert button is a great tool for seniors that are living independently. This device can be worn on a pendant or as a wristband and will allow the person to quickly and easily contact help without needing to reach a phone.
However, it is very important to understand the limitations of this type of medical alert, including when the button may not work. Each receiver is different, but they usually will work when the button is within 400 feet of the unit.
However, this distance can be effected by the types of walls in the home or other structures. Some buttons are water-resistant, so can be worn for hand washing and kept right outside the shower and while bathing, however you should check with your medical alert company before wearing your medical alarm pendant in the pool or while swimming.
