ABSTRACT:
A radio selective calling receiver protects security by remaining inoperable despite manipulation of switches by a third party. The receiver includes a switch state detector which 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, outputs the withheld command input when the correct password is inputted. The receiver also includes an input password judging unit which 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.
