A mobile telephone with an emergency call capability protector monitors a battery power supply circuit with an emergency call reserve power detector to determine when the power remaining in the battery power supply circuit has decreased beneath a pre-selected minimum emergency call reserve power level that is greater than the absolute minimum level detected by a monitor and battery depletion detector. A microprocessor operating in accordance with a program stored in an emergency call capability program memory selectively inhibits, subject to override, the making of non-emergency calls and terminates ongoing non-emergency calls when said power detector determines that the power supply circuit has gone beneath said pre-selected minimum emergency call reserve power level. |
