Abstract: In a selective call receiver including a display and a message memory, when receiving a message including a schedule, it is checked whether a received schedule is overlapped with a stored schedule which has been stored in the memory. When the received schedule is overlapped with the stored schedule, a prompt mark indicating duplication is displayed on screen. Depending on a user's instruction, at least one schedule is selected from the received schedule and the stored schedule. When the received schedule is selected, the received schedule is registered into the memory while deleting the stored schedule from the memory.
