The receiver/pager will then alert the consumer if any of his/her personal items equipped with the transmitters are about to be left behind or separated from him/her. Audible alarm or vibrations alert the consumer once any item equipped with a transmitter is beyond the distance range of the receiver/pager. The receiver/pager can also alert the consumer as to which particular transmitter is out of range using any of the assignable item descriptions available on the receiver/pager (ie: "Wallet", "Cell Phone", PDA", etc . . .).
