ABSTRACT:
A system and method for reducing the risk of cellular phone loss, misplacement, and/or theft, the system including a wireless transmitter in a cell phone for intermittently sending security signals to a device (e.g. pager) to be worn by a user. The device includes an alarm which is actuated when either the strength or amplitude of the security signal(s) falls below a predetermined threshold or when such security signals are not received by the device (e.g. pager) for a predetermined period of time. Accordingly, the user is alerted to potential loss, misplacement, and/or theft of the cell phone.
