Our At Home personal help buttons, including the falls pendant, utilise a low power (60µW) radio frequency signal (RF) to connect with a Chiptech base unit. These RF transmissions are very brief, typically 0.2 seconds, and only occur at automated test times (typically every 7 hours), and when they are activated by a button press. Our personal help buttons are designed and manufactured to reduce electromagnetic interference with other electronic devices. The pendants can be worn by a user with a pacemaker or other implanted electronic device. However, if the end user has any concerns, please request they consult their medical specialist for further advice.
