    * This device is not designed to compete in radiation
          power, the advantage is to allow jamming only the
          selected targets, not to spill radiation to unwanted area.

    * If it is desired to have larger coverage, it is suggested to
         use multiple units, distributed 15 meters apart like
         cellular base station to eliminate dead corners, but not
         to spill to unwanted area.

    *Due to the wide frequency bands coverage, this device
          will become warm after one hour continuous usage.
          It is a normal phenomenon, However, user should try t0
          use in an open space at temperature less than 35 C.

          the housing should be pointed to the target direction.
          To be effective, device should be placed closer to
          the spot having strongest base station signal
          in the coverage area.

    *User can use a smart phone to measure signal strength.
