Abstract
A mobile unit having a unit for transmitting and receiving signals to and from a base station by radio telephony, an input unit for use in entering information, a display and a control unit, is provided with a first memory in which 'unwritten' or 'written' is stored as a state of a password for enabling the dial lock, and a second memory in which a password for enabling the dial lock is stored. When a dial lock signal is supplied from the input unit, the control unit writes a password entered at the input unit in the second memory and changes the state of a password in the first memory from 'unwritten' to 'written.' Thereafter, except after providing the password, the mobile unit cannot be used for calling. Moreover, the password cannot be modified.
