Abstract

PROBLEM TO BE SOLVED: To allow a portable phone to surely cope with sending of an emergency call and to enhance its use-friendliness by suppressing consumption of a battery, when a battery residual capacity is decreased without the need for provision of a standby battery to the mobile phone. SOLUTION: In this portable phone, a storage section 7 stores a contact destination number on emergency and operating procedures in advance. When a battery voltage detection section 2 detects that the consumption of a battery 1 exceeds a prescribed value, a switch is thrown to a position (b) to stop supply of power. When an emergency call detection section 6 detects the occurrence of an emergency call through the depression of an emergency button 4, power from the battery 1 is supplied to each section via the switch thrown to a position (c). A control section 13 reads the stored contact destination number and the operation procedures from the storage section 7, allows a display section 8 to display them, so as to discriminate whether or not an operation entry is a call transmission instruction. In the case that the operation entry indicates transmission instruction, the call is made to the designated contact destination number and when the end of speech is detected, the switch is again thrown to the position (b) and supply of power is stopped.
