1. A radio telecommunication apparatus comprising:
- signal-receiving means for receiving a signal containing a message, for demodulating the signal, and for outputting the demodulated signal;
memory means, connected to said signal receiving means, having a storage area for storing at least one message contained in the demodulated signal output by said signal-receiving means;
timer means for measuring time and outputting time data;
first input means for inputting and holding message-erasing time data representing a timing of erasing the message stored in said memory means; and
first message-erasing means, connected to said timer means, said first input means, and said memory means, for erasing a message stored in the memory means, said first message-erasing means comparing the time data output by the timer means and the message-erasing time data input by the first input means with each other, and erasing the message stored in the memory means if a coincidence is detected between the time data and the message-erasing time data.

Abstract
A radio telecommunication apparatus comprising a memory circuit for storing a message received, a timer circuit, an input section, and a message-erasing circuit. The input section is operated to set a timing of erasing the message stored in the memory circuit. When the time measured by the timer circuit becomes identical to the message-erasing timing set by operating the input section, the message-erasing circuit automatically erases the message stored in said memory circuit.

5. A method of erasing messages in a radio telecommunication apparatus comprising memory means having a storage area for storing at least one message received, and timer means for measuring time and outputting time data, said method comprising the steps of:
-
setting and holding message-erase time data representing a timing of erasing the message stored in said memory means; and comparing the time data output by the timer means and the message-erasing time data input by a first input means with each other; erasing a message stored in the memory means if a coincidence is detected between the time data and the message-erasing time data.

6. A radio telecommunication apparatus comprising:
-
signal-receiving means for receiving a signal containing a message, for demodulating the signal, and for outputting the demodulated signal; memory means, connected to said signal receiving means having a storage area for storing a plurality of messages each contained in the demodulated signal output by said signal-receiving means; timer means for measuring time and outputting time data; input means for inputting and holding message-erasing time data in association with the respective messages stored in said memory means; and message-erasing means, connected to said timer means, said input means and said memory means, for selectively erasing the messages stored in the memory means, said message-erasing means comparing the time data output by the timer means and the message-erasing time data input by the input means with each other, detecting whether or not the time data coincides with one of the message-erasing time data, and selecting and erasing that one of the messages stored in the memory means which corresponds to the message-erasing time data detected as coinciding with the time data. - View Dependent Claims (7)
