Hereinafter, FIGS. 3 and 4 according to the present invention will be described with reference to the configuration of the PDA of FIG. The operation method of 4 will be described in detail.

First, when a user wants to set a lock function (Key-Lock) on the PDA, the user inputs a password through the key input unit 11 and sets a lock function, and the control unit 30 sets the input password. Is stored in the RAM 60. In addition to the password, the RAM 60 further stores user information (name, address, mobile phone number, etc.) input by the user through the key input unit 11. Will be.

When the lock function is set by the password input as described above (S10), the controller 30 thereafter performs a user authentication process by comparing the password for each use request of the PDA.

That is, the controller 30 outputs a message " Please enter a password " through the display unit 12 at the time of use request of the PDA (S20) (S21), and thus the user inputs the key input unit 11 When the password is input through the control unit 30 performs a user authentication process for comparing the input password and the password previously stored in the RAM (60) (S22).

If both passwords are the same, and the user authentication is successful (S30), the controller 30 determines the user as a legitimate user, releases the lock function, and performs the normal operation of the PDA according to the user's request. (S31) If both passwords are not the same, the display unit 12 re-outputs a message requesting a password input and re-executes the user authentication process.

The controller 30 continues to perform the user authentication process a predetermined number of times (for example, three times) (S40). If both passwords are not the same and the user authentication fails continuously, the controller 30 switches to the lost mode and locks the lock. In this case, the control unit 30 temporarily permits use of some predetermined keys (for example, numeric keys, etc.) according to the lost mode, which will be described in detail below. do.

The controller 30 outputs the following scheduled menu screen through the display unit 12 as it is switched to the lost mode (S41).

<Lost Mode>

1: Check user information

2: Send text message

3: Direct call

......................

Accordingly, the user selects and selects a specific specific item from among the above items through the key input unit 11, and the specific item is designated through numeric key input through the key input unit 11.

If the user selects 1, which is a "confirm user information" item, the controller 30 reads user information stored in the RAM 60, that is, user name, address, telephone number, and the like. This is output through the display unit 12, so that the PDA learner can make a phone call to the original owner of the PDA by dialing the output user's telephone number.

If the user selects "2," which is a text message transmission item, the control unit 30 switches to the text message transmission mode so that the user can input a text message within a predetermined time. The 30 permits the use of the text key of the key input unit 11 only for a predetermined time in accordance with the switching to the text message transmission mode. Accordingly, the PDA learner writes the following text message through the key input unit 11, "I have acquired the PDA. Please contact 019-2201-XXXX", and the control unit 30 is prepared as described above. Sending a text message to the CDMA communication module 40 along with a mobile phone number previously stored by the original owner of the PDA, the short message service which is one of the mobile communication services. The short message service is an access / paging channel or a traffic channel for receiving a short message between mobile terminals or between a mobile communication terminal and a short message. A service that allows short text messages to be exchanged between receivers. The size allocated to the user data field is up to 255 characters. The CDMA communication module 40 is configured to transmit the received data in a format that can be transmitted in the form of a short message on the mobile communication network so as to be interpreted by the exchange of the CDMA mobile communication network.

Therefore, the original owner of the PDA can receive a text message, "Obtained the PDA. Please contact 019-2201-XXXX" through his mobile communication terminal, thereby making a phone call with the learner of the PDA.

In addition, if the user selects "direct call" item 3 among the above items, the control unit 30 requests a direct telephone call with the original owner of the PDA through the display unit 12. Please press the button for 2 seconds. " Accordingly, the PDA learner presses a confirmation key for about 2 seconds according to the above message. Accordingly, the control unit 30 uses the CDMA communication module 40 to store a telephone number (mobile phone number) previously stored by the user. By sending a call to the call connection request, a direct telephone call can be made between the original owner of the PDA and the PDA learner.

When switching to the lost mode as described above, the controller 30 performs a proper operation on the corresponding item selected on the menu screen according to the lost mode (S42), thereby simply contacting the learner of the PDA and the original owner of the PDA. Let this be done.

On the other hand, the control unit 30 maintains a locked state to prohibit use of all keys after the proper operation according to the lost mode is completed.

As mentioned above, preferred embodiments of the present invention are disclosed for purposes of illustration, and those skilled in the art can improve and change various other embodiments within the technical spirit and technical scope of the present invention disclosed in the appended claims below. , Replacement or addition would be possible.
