The KX-TGQ500 is designed for easy handling with its extra loud volume and large buttons that announce the pressed key number for confirmation. The SOS emergency function provides added security. The device connects wirelessly to a router and can be placed anywhere in the home, making a connection to the phone socket unnecessary. Seniors can benefit from features such as the SOS function, hearing aid compatibility, and an LED that signals incoming calls. Additionally, the pressed key number is audibly repeated, which is very helpful for those with impaired vision.
