ABSTRACT:
A cellular telephone set is capable of allowing release dial lock function by a child even when parent manages an identification number. A control portion of the cellular telephone set is responsive to input of identification number through a key operating portion after dial lock condition is established by dial lock means to make judgment whether the input identification number is a dial lock releasing number in a dial lock releasing number storage region. When the control portion makes judgment that the identification number is the dial lock releasing number, dial lock condition of a predetermined function preliminarily set in an identification number setting information storage region is released.
