Take into consideration the effects of the mounting location when mounting the
Tag. Communications range may be reduced if the Tag is near certain objects.
The extent to which the distance will decrease depends on the actual material
and its shape. Check the back of the Tag for the effects of metal and resin ob-
jects.
The graph below shows the percentage reduction in communications range
when a metal object is mounted behind the Tag. The horizontal axis represents
the distance between the metallic plate and the Tag. The vertical axis represents
the percentage decrease in communications range, where communications
range with no metal object interference is taken to be 100%.
Range between metallic plate and back of Tag (mm)
The following table shows the results of measuring the communications range
when the Tag is mounted to a resin object. The extent to which the distance will
decrease depends on the actual resin material and its shape.
