Cautions for Wireless Equipment
This product is a wireless device that can use the entire 2.4 GHz band, and is able to avoid the mobile entity identification device range. The GFSK method is adopted as the radio wave method, and the interference distance is 10 m. The 2.4 GHz band is also used in medical devices, Bluetooth, and wireless LAN devices of the IEEE 802.11b/11g/11n standards. Before using this product, check that there are no other “radio stations”* operating nearby. If electromagnetic interference occurs between this product and other “radio stations”*, move this product to another location or stop using this product. * Other “radio stations” refer to industrial, scientific and medical devices using the 2.4 GHz band, the same as this product, other radio stations of this type, licensed radio station premises for a mobile object identification system that is used in factory production lines, certain non-licensed low power radio stations, and amateur radio stations.
WARNING
