V680-D1KP52M-BT01/-D1KP52M-BT11
Mutual Interference with RF Tags (Reference)
To prevent malfunctioning due to mutual interference when using more than one RF Tag, leave
sufficient space between them as shown in the following diagram.
Influence of RF Tag Angle (Reference)
Install Antennas and RF Tags as parallel to each other as possible.
Communications are possible even when an Antenna and an RF 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.
