  • Page 8: Introduction

    By using the BA72A you are provided with a terminal-orientated, ergonomi- cal and customer-friendly cashier’s workplace. The BA72A is the enhanced version of the BA72. It is equipped with the PanelLink technology with the new highlights: cable distance support up to 5m, flexible All-in-One cable for Touch Screen, loudspeaker and supply volt- age.

  • Page 9: Advantages At A Glance

    The low-energy, flickerfree and radiation-free colour monitor of the BA72A is an Active-Matrix-Display in TFT-technology (Thin Film Transistor). Therefore, it is especially suited for multimedia applications as it offers brilliant colour representation, an excellent contrast ratio and a high dis- play speed.

  • Page 10: Unpacking And Checking The Delivery Unit

    If damage has occurred during shipping or if the package contents do not match the delivery note, immediately inform your Wincor Nixdorf sales outlet. Transport the device only in its original packaging (to protect it against im- pact and shock).

  • Page 11: Ba72A Components

    BA72A Components Screen Module The screen module represents the main unit of the BA72A. It comprises of a TFT-LCD colour screen, the TFT-interface and an inverter that genera- tes the voltage for backlighting the screen. As an option the screens are available with Touch Screen including a loudspeaker.
