 Influence of Surrounding Metal
The V680-D8KF67M can be surface-mounted or it can be embedded in metal. However, do not allow
the height of the metal to exceed the height of the V680-D8KF67M.
 Mutual Interference of RF Tags
If you use more than one RF Tag, separate them by at least the interval shown below to prevent
malfunctions due to mutual interference.
If the distance between the RF tags is too short, read / write distance will be reduced.
