Emergency cellular telephone apparatus
First Claim
1. Emergency cellular phone apparatus including, in combination:
- a cellular phone housing;
radio frequency transceiver means for transmitting and receiving modulated radio signals;
audio processing means for voice and signaling modulation and demodulation of said radio signals;
central processing means for controlling call setup activities on the cellular network;
power supply means for delivering necessary voltages and currents to said radio frequency transceiver means and said audio processing means and said central processing means;
actuator means manually accessible from a location external to said cellular phone housing for actuating said radio frequency transceiver means and said audio processing means and said central processing means and said power supply means;
said actuator being modular includes electrical connector means and is selectively connectable to and disconnectable from said cellular phone housing;
said cellular phone housing defining a recess for accommodating said actuator means;
said cellular phone housing includes a socket communicating with said recess for receiving said electrical connector means when said actuator means is accommodated by said recess;
call restriction means in operative association with said central processing means for restricting modulation of said radio signals, during call initiation by operation of said actuator means, to signals required for connection to a predetermined emergency phone number;
incoming call answering means in operative association with said central processing means for establishing audio communications upon actuation of said actuator means by a user of said emergency cellular phone apparatus when an incoming call occurs.

Abstract
Emergency radio telephone apparatus includes a housing, a radio transceiver for receiving and transmitting modulated radio signals, an actuator connected to the housing for actuating the transceiver and initiating the process of making connection to a predetermined emergency phone number. The actuator may alternately be of modular construct, not permanently connected to the housing allowing easy replacement of the emergency call actuator with a modular construction telephone keypad and display, thereby converting the emergency-only radio telephone into a full-functioned radio telephone. A cover can be attached to the transceiver allowing access only to the emergency call actuator thereby restricting calls to only the emergency number. Cover, modular keypad, modular actuator, or transceiver can have a lock to prevent removal of modular components.
