Notes on Using 2.4 GHz Devices

WLAN devices operate on the same frequency band used by home electric appliances such as
microwave ovens, industrial, scientific and medical equipment, premises radio stations for identifying
mobile units used in the manufacturing lines of plants (radio stations requiring a license), specified
low power radio stations (radio stations requiring no license) and amateur radio stations.
Before using handset, confirm that premises radio stations, specified low power radios, and

amateur radio stations are not in use nearby.
In the event of handset causing harmful radio wave interference with premises radio stations for

identifying mobile units, promptly change the operating frequency or stop radio wave emission by
turning off the power, etc. and then contact a SoftBank Shop or
measurement against the cross talk (e.g. installing partition.)
Also, in the event of handset causing radio wave interference with specified low power radios and

amateur radio stations, contact a SoftBank Shop or

Notes on Using 5 GHz Devices

In 5 GHz frequency bandwidth, handset can use following bands:
5.2 GHz band (W52/36, 40, 44, 48 ch)

5.3 GHz band (W53/52, 56, 60, 64 ch)

5.6 GHz band (W56/100, 104, 108, 112, 116, 120, 124, 128, 132, 136, 140 ch)

Using wireless LAN built-into handset in 5.2/5.3 GHz outside is prohibited by the Radio Law.
Reception Interference Caused by Bluetooth
®
Bluetooth and WLAN (IEEE802.11b/g/n) use the same frequency band. Using near Wi-Fi (WLAN)
devices may cause radio interference, low-communication speed, noise or connection fault. Or may
cause communication interruption or sound distortion when streaming data is played. In that case,
take the following measures.
Provide distance between Wi-Fi (WLAN) device and Bluetooth

by device.
If the problem persists, power off Bluetooth
