Apparatus and method for operating a cellular or portable telephone
First Claim
1. A telephone, comprising:
- a display device;
a keypad;
a transmitting and receiving circuit;
a controller for the transmitting and receiving circuit, the controller being connected to receive input signals from the keypad and to supply output signals to the display device;
a memory for the controller, the memory containing a service program accessible selectably through a master lock code and a one-time lock code, the master lock code permitting access to selected portions of the service program and the one-time lock code usable only once to permit access to a subset of said selected portions of the service program;
wherein a serial number is uniquely associated with said telephone and the one-time lock code is generated based upon the serial number and the master lock code.

Abstract
A technique for activating a cellular or portable telephone includes a circuit for transmitting and receiving signals, a controller for the transmitting and receiving circuit, and a display device, e.g., liquid crystal display. A service program stored in a memory is accessible through a first code and a second code. The first code permits access to portions of the service program, and the second code permits access to fewer portions of the service program. The second code is generated based upon data associated with the telephone, e.g., a serial number and/or the first code. The service program is prevented from being accessed through the second code after the second code is used once. The portions of the service program that are accessible through the second code may be a subset of the portions of the service program that are accessible through the first code, and the portions of the service program that are accessible through the second code may include a routine for storing or setting the telephone number assigned to the apparatus.

8. An apparatus, comprising:
-
means for transmitting and receiving signals; control means for controlling said transmitting and receiving means; display means for displaying information, said display means being connected to said control means; memory means for storing a service program, said memory means being connected to said control means, the service program being accessible through a first code and a second code, the first code permitting access to portions of the service program and the second code usable only once to permit access to fewer portions of the service program; means for generating the second code based upon numerical data associated with said apparatus; and means for preventing the service program from being accessed through the second code after the second code is used once. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18)

19. A method for operating a telephone having a memory containing a service program, said method comprising the steps of:
-
permitting portions of the service program to be accessed through a first code; permitting fewer portions of the service program to be accessed through a second code which is usually only once; generating the second code based upon numerical data associated with said telephone; and preventing the service program from being accessed through the second code after the second code is used once. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
