devices
In the bandwidth used by this cell phone, in
addition to home electric appliances such as
a microwave oven and industrial/scientific/
medical devices, in-plant radio stations
used to identify mobile objects used in
production lines of a factory that require a
license, specified low power radio stations, or
amateur radio stations that do not require a
license (hereafter "other radio stations") can
be in operation.
1. Before using this cell phone, confirm that
"another station" is not being operated
nearby.
2. In the event of this cell phone causing
harmful radio wave interference with
"another station", promptly change the
location or stop radio wave emission by
turning off the power, etc.
