PROBLEM TO BE SOLVED: To make it possible to inform of the existence of an unread message even after receiving a message. SOLUTION: Message data received by data communication are stored in a message memory 5b. At the time, an unread flag is allowed to correspond to the message flag, and at the time of starting each application program by an access to an application program memory 10a, unread flags stored in the memory 5 are checked. When at least one of the unread flags is set up to '1' (ON), an alarm for warning the existence of the unread flag is displayed on a color display part 8. |
