A portable radio information terminal with a message-notification mode/message-storage mode setting unit, a message-notifying-device-operation control unit and a display-mark turning-on/off unit. The message-notification mode/message-storage mode setting unit sets the portable radio information terminal in a message-notification mode for notifying the user of a message in the event of an incoming information signal conveying the message or in a message-storage mode for halting an operation to notify the user of a message in the event of an incoming information signal conveying the message. The message-notifying-device-operation control unit enables a selected message-notifying device to notify the user of an incoming information signal in the message-notification mode or prevents a selected message-notifying device from notifying the user of an incoming information signal in the message-storage mode. The display-mark turning on/off unit means displays a display mark of a selected message-notifying device on the screen of an image displaying unit in the message-notification mode or halts an operation to display display marks of all message-notifying devices including a selected message-notifying device in the message-storage mode.
