Restricting the operation of an electronic device

A cordless telephone for making an emergency call upon sensing separation of a handset from a charger of a base unit. The handset is normally set in the charger in an idle state. A handset sensor detects separation of the base unit from the charger, and a user interface is used to input an emergency mode setting command and a phone number for an emergency call. A memory stores the input phone number for the emergency call, and a telephone answering device generates a voice message annunciating an emergency situation. When the handset is separated from the charger, a controller mutes a speaker, forcedly hooks off the base unit, reads the phone number for the emergency call from the memory, dials the read phone number, and sends the voice message. A microphone can also be enabled in order to transmit the sounds of the emergency situation to a called party.
