ABSTRACT:
If a user attempts to provide a protection attribute to a new message while the number of old messages which have a protection attribute and are retained is equal to the maximum number of protected messages, a portable radio terminal, such as a pager system, displays on an LCD 13 the oldest received message having a protection attribute. Only the messages having a protection attribute are displayed on the LCD 13 in chronological order of receipt by rotating a rotary switch 4. A message whose protection attribute is canceled is determined by pressing the rotary switch 4 while a message which the user desires to cancel is displayed. Simultaneously, the foregoing operation enables a new message which the user desires to protect to be provided with a protection attribute. An operation for canceling the protection attribute of an old received message and an operation for providing a protection attribute to a new message, both being required when the number of protected messages is equal to the maximum number of protected messages, are grouped into one operation, thus rendering simpler an operation for providing a protection attribute to a new message.
