Abstract

A cellular telephone set is capable of being released 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.

Claims

1. A cellular telephone set being set and releases of various function when an input identification number is judged as correct identification number including dial lock for disabling key input, comprising:

holding means for holding a preliminarily set dial lock releasing number dedicated for releasing dial lock;

judgment means for making judgment whether the input identification number input in dial lock condition is said dial lock releasing number held in said holding means; and

means for releasing dial lock condition when said judgment means makes judgment that said input identification number is said dial lock releasing number.

2. A cellular telephone set as set forth in claim 1, wherein functions to be released dial lock condition by said dial lock releasing number can be set arbitrarily.

3. A cellular telephone set as set forth in claim 2, wherein said function is a calling function.

4. A cellular telephone set as set forth in claim 2, wherein said function is a calling function to preliminarily registered telephone numbers.

5. A cellular telephone set as set forth in claim 2, wherein said function is an internet browsing function.

6. A cellular telephone set as set forth in claim 2, wherein said function is transmitting and receiving function of an electronic mail.

7. A cellular telephone set as set forth in claim 1, wherein a plurality of dial lock releasing numbers can be set arbitrarily, each dial lock releasing number corresponds to at least one function.

8. A dial lock releasing method in a cellular telephone set being set and releases of various function when an input identification number is judged as correct identification number including dial lock for disabling key input, comprising:

step of making judgment whether the input identification number input in dial lock condition is a dial lock releasing number a preliminarily set dial lock releasing number dedicated for releasing dial lock held in a holding means;

step of releasing dial lock condition when said judgment means makes judgment that said input identification number is said dial lock releasing number.

9. A dial lock releasing method set as set forth in claim 8, wherein functions to be released dial lock condition by said dial lock releasing number can be set arbitrarily.

10. A dial lock releasing method set as set forth in claim 9, wherein said function is a calling function.

11. A dial lock releasing method as set forth in claim 9, wherein said function is a calling function to preliminarily registered telephone numbers.

12. A dial lock releasing method as set forth in claim 9, wherein said function is an internet browsing function.

13. A dial lock releasing method as set forth in claim 9, wherein said function is transmitting and receiving function of an electronic mail.

14. A dial lock releasing method as set forth in claim 8, wherein a plurality of dial lock releasing numbers can be set arbitrarily, each dial lock releasing number corresponds to at least one function.

15. A program for performing a dial lock releasing method in a cellular telephone set being set and releases of various function when an input identification number is judged as correct identification number including dial lock for disabling key input, making a computer executing:

process of making judgment whether the input identification number input in dial lock condition is a dial lock releasing number a preliminarily set dial lock releasing number dedicated for releasing dial lock held in a holding means;

process of releasing dial lock condition when said judgment means makes judgment that said input identification number is said dial lock releasing number.

16. A program as set forth in claim 15, which makes said computer to execute process of releasing dial lock condition of the preliminarily set function upon inputting of said dial lock releasing number.
