A recordingreproducing apparatus includes an optical source and a near-field light generating unit. Transfer port apparatus is adapted to be coupled to a movable canister and a stationary isolator. The MS determines a first Precoding Matrix Index and a second PMI for interference from an adjacent Base Station. The sensor is calibrated using a known target. The received tuning values are stored in to a memory of the device including the RF radio module and applied to the RF radio module. Extensive use of the high resolution and bandwidth of such user input devices is combined with strategies to avoid unintentional inputs and with dense and intuitive interactive graphical displays.
