ABSTRACT:
The present invention pertains to an apparatus and method for automatically disabling cell phone ringing and/or cell phone beeping. An RF transmitter is used to transmit an RF non-audible mode or control signal. Upon receiving the non-audible mode or control signal, the cell phone and/or beeper automatically disables its audible alarm. Users are notified of incoming calls and/or pages by means of blinking lights or vibration. When the user no longer receives the non-audible mode or control signal or upon the elapse of a fixed, pre-determined amount of time, the cell phone and/or beeper automatically reverts back to its normal mode of operation whereby incoming calls and pages are indicated by cell phone ringing and pager beeping.
