||The recalled Visonic Amber SelectX Personal Emergency Response System (PERS) kit enables a user to push a button on a pendant to signal a request for assistance. An Amber kit consists of one wireless pendant worn by the user, one Amber brand base station, generally connected to a phone line, a power supply and backup battery. Base stations are white, rectangular and measure about 9-inches wide by 7-inches deep by 2-inches high with grey emergency, call and check buttons. Recalled models have catalog number 0-100729 and serial numbers 1612002383 through 501206949. The first four digits represent manufacture dates April 2012 through December 2012 in WWYY format. The first two digits are week of manufacturer and the second two numbers are the year of manufacture. For example serial number 2312 600299 indicates a manufacturing date of the 23rd week of 2012 or roughly June 2012. Each unit has an external label on the back of the base station, with the product name and serial number. Amber base stations previously recalled due to a different problem also had catalog number 0-100729 and serial numbers 2308600299 through 3013079617.
