• The communication range varies depending on the installation site environment. This is because a metal material and
the ground reflect a radio wave, and water and human body absorb it. Locate an antenna and tag in the communica-
tion range and check the radio wave environment in advance.
• The Read/Write antenna model V690-HMG01 has a communication test command to check the radio wave environ-
ment at a working site. (Refer to Section 3-5.)

5 mW for 2 m mode and 10 mW for 5 m mode.
Circularly polarized wave
2 m mode/5 m mode switched by a host command. (Section 3-2)
2 m mode: 0.2 to 2.0 m (Reference value)
5 m mode: 0.2 to 5.0 m (Reference value)
* Conditions for reference value
• Ambient temperature 20±5°C
• Place the tag at a suitable rotating position so that the logo "omron" can become upright.
(Refer to the figure below.)
• On a medial axis of antenna placed at 1.5 m high in a large room where radio wave noise
is minimized.
