A December 2013 recall has been expanded for Linear Personal Emergency Reporting System (PERS) transmitters due to low battery signal failure. The original recall of 48,000 transmitters has been expanded to include an additional 175,000 transmitters.
The batteries used in the transmitters can fail to sound a low battery warning, causing the user to believe the device is properly functioning. These transmitters allow users to push a button to request assistance in an emergency situation. Three different models are included in the recall, and sold between July 2008 and July 2011 by authorized distributors. Consumers with recalled transmitters should contact the company for a free replacement transmitter.
