 V680-HS63
 Effect of Surrounding Metals on the Antenna (Reference)
In addition to surface mounting, it is also possible to embed the V680-HS63 in a metal casing to protect
it from being struck by other objects. To prevent malfunctioning, allow a space of at least 30 mm
between the Antenna and the sides of the metal casing. If the space is less than 30 mm, the read/write
distance will be greatly diminished. In addition, the height of metal casing must not exceed that of the
Antenna.
 Mutual Interference between Antennas (Reference)
To prevent malfunctioning due to mutual interference when using more than one Antenna, leave suffi-
cient space between them as shown in the following diagrams.

Note
1. Do not bend the cable into a curve
tighter than 22 mm in radius.
2. The communications distance will
be reduced significantly if the
Antenna is installed closer than 30
mm to metal surfaces.
