Installation
Mutual Interference with Tag (Reference)
To prevent malfunctioning due to mutual interference when using more than one Tag, leave sufficient
space between them as shown in the following diagram.
Influence of Tag Angle (Reference)
Install Antennas and Tags as close to parallel to each other as possible. Communications are possible
even when an Antenna and a Tag are mounted at an angle, but the communications distance will be
shortened. The relation between the angle and the communications distance is shown below.
