Cautions on using Bluetooth devices
Bluetooth operates at radio frequencies assigned to the in-
house radio stations for a mobile object identifier that have
to be licensed and are used in production lines of a factory,
specific unlicensed low power radio stations, and amateur
radio stations (hereafter, referred to as "another radio
station") in addition to industrial, scientific and medical
devices or home electric appliances such as microwave
ovens.
1. Before using the handset, make sure that "another radio
station" is not operating nearby.
2. If radio interference between the handset and "another
radio station" occurs, avoid interference by moving
immediately to another place or "turning off the power".
3. Contact the number listed in "General Inquiries" on the
last page for further details.
