Note: The read range shape that extends behind the 1555 is determined by where the
user is standing, and in which hand he/she holds the 1555. In Figure E-2, the user
operated the 1555 reader in the right hand, and his body blocked the RF. If the 1555
reader is operated in the left hand, the user's body blocks the RF to the right and
behind the 1555.
