 Mounting on Non-metallic Material
Mount the RF Tag using M3 flat-head screws
from the marked side.
Tighten the screws to a torque of 0.3 to 0.5 N·m.
 Mounting on Metallic Material
The communications range will decrease if there
is metal at the back of the V680-D1KP66T RF
Tag.
If the RF Tag is mounted on metallic material,
use the V600-A86 Attachment (sold separately)
or a non-metallic spacer (e.g., plastic or resin).
Refer to RF Tag Installation Precautions in Section 11 Appendices for information on the effect of metal at the back surface,
