Notes on Using 2.4GHz 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.
n Before using handset, confirm that premises radio stations, specified low power radios, and
amateur radio stations are not in use nearby.
n 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 SoftBank Customer Support for
