    Ease of installation

    Corner keystone correction enables angled projection

    All you need to do is designate for points as the corner of the projected image, 
    and this function easily carries out horizontal and vertical keystone correction.

    Curved screen correction

    Barrel and pincushion distortions are easily corrected when projecting 
    onto a curved screen.

    Easy remote monitoring and control over a LAN

    Web browser on a computer connected through a wired LAN system lets you remotely operate projectors and check their status.

    In addition, Multi Monitoring and Control Software is available for monitoring and controlling multiple Panasonic projectors from a single PC.

    The wired LAN terminal is compatible with PJLink™ (class1), an open protocol that is used by many manufacturers, to enable integrated control of systems that contain different brands of projectors.

    Easy lamp and air filter replacement simplifies maintenance

    For easier maintenance, you can replace the lamp from the top and the air filter from the side, even after the projector is installed on the ceiling. This eliminates the need to detach the projector from its mounting bracket in ceiling-mounted applications.

And the SPDriver setting should be set to "Touch mode". ** Multi-touch Screen LED Display : LFB70 and BF1 Series (TH-50LFB70/65LFB70/80LFB70 and TH-50BF1/ TH-65BF1/ TH-80BF1)
