* Maximum blocking power is in the housing back direction,
   on a horizontal plane. Target should be in this plane.

* 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 to
  use in an open space at temperature less than 35 C.

* Device should be placed on a flat space, back side of 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.
