Effect of Surrounding Metals (Reference)
The V680-D8KF67M can be surface-mounted or it can be embedded in metal. If it is embedded in
metal, the height of the metal casing must not exceed that of the RF Tag.
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.
● V680-HS52 and V680-D8KF67M ● V680-HS63 and V680-D8KF67M
