・Noise Interference, metals, and other transceivers are not allowed around the transceiver.
・Communication distance may be shorter than the above value due to the tag deviation.
・Must not be any slant between the transceiver and the antenna center of the tag.
・For the gain setup, see the programming manual.
-important-
(When Flash-ROM is rewritten,) Do not change the gain value more than 100 times.
