<p>The present invention is directed toward realizing a radio selective calling receiver that protects security by remaining inoperable despite manipulation of switches by a third party. The device is composed of: a switch state detector that detects the manipulated state of switches of the switch unit, and that, when functions are selected while a password input mode is in effect, withholds command input by selection switches when the correct password is not inputted, and outputs the withheld command input when the correct password is inputted; an input password judging unit that collates an input password with a collation password stored in a collation password memory, judges whether or not the inputted password is correct, and outputs a judgment result; a password input control unit that causes a display unit to display a request for password input when in the password input mode; a function/item selection control unit that outputs a selected function activation signal and a selected item command signal based on command input from the switch state detector; and a password input mode setting unit that sets or cancels the password input mode. <IMAGE></p> |
