The present invention provides a method and apparatus for dynamic adjustment of a sampling plan. Equipment data is collected, manually or automatically. The digitizer includes a data outlet for transferring the detected input as overlay data so the touchpad can visually display the detected input on its touchscreen. As a result, even in a structure provided, the engine section 40 does not need a large capacity non-volatile storage region, thereby configuring a compact mobile communication terminal. The failure information can include, for example, a zone identifier andor an action code.
