1.2. Notes Concerning Radio Waves

This product has received technical standards conformity certification.

When using the IEEE802.11b, IEEE802.11g and IEEE802.11n (2.4GHz) communication, the 2.4GHz frequency
band is used. In this frequency band, industrial equipment such as microwave ovens, scientific, and other medical
equipment, other homogenous wireless stations, local wireless stations for mobile identification that requires
license used in factory production lines, specific low powered wireless stations and amateur wireless stations
(assumed hereafter as “Other wireless stations“), etc., that do not require licensing are operated.
(1) Confirm that “Other wireless stations” are not being used within the vicinity before using this product.
(2)
If, by any chance, interference occurs between this product and the “Other wireless stations“, change the
channel being used by this product, change the location of the device or stop using the device.
(3) In addition, contact us when interference is generated and problem occurs.

It is not possible to communicate with a Bluetooth device using the 2.4GHz band.

When using the IEEE802.11b, IEEE802.11g and IEEE802.11n communication, wireless devices use all 2.4GHz
bands, and the band of mobile identification device can be avoided. The DS-SS and the OFDM methods are
adapted, and the interference distance is 40 meters.
2.4 : Wireless device uses 2.4GHz band.
DS/OF : DS-SS and OFDM methods.
4
: Assumed interference distance of 40m or less.
■■■ : It means all bandwidth can be used and the bandwidth of mobile
identification device can be avoided.

When this product is used with 2.4GHz band and the channel is set manually, the following content is
recommended by the ARIB standard of Association of Radio Industries and Businesses.
“When using this equipment with 2.4GHz band, it is recommended to make either ch1, ch6, or ch11 as the
channel setting in order to decrease the interference and for the improvement of frequency utilization efficiency.“
However, in order to avoid interference with systems other than wireless LAN, it is not limited if it is necessary to
use other than the recommended 1,6,11 channels.

When using a dual channel, there is a possibility of causing interference to other wireless stations that use the
same frequency band.
・ When dual channel is “Enable“, confirm that no interference is caused to the radio signal condition of the
surrounding of other confirmed wireless stations.
・ Change the setting to “Disable“ immediately when interference is generated in other wireless stations.
