wireless
LAN
When
communicating
with
a
2.4GHz/5GHz
LAN,
be
careful
about
the
following.
Microwave
ovens
and
other
industrial,
scientific,
and
medical
equipment,
as
well
as
indoor
wireless
stations
(wireless
stations
requiring
permits)
and
special
low
‐
power
wireless
stations
(wireless
stations
not
requiring
permits)
used
for
identifying
mobile
units
used
in
plant
manufacturing
line
etc.,
as
well
as
amateur
wireless
stations
(wireless
stations
requiring
permits)
operate
in
the
frequency
band
used
by
this
product.
Before
using
this
product,
double
check
that
no
indoor
wireless
stations,
special
low
‐
power
wireless
stations
for
mobile
unit
identification,
or
amateur
wireless
stations
are
in
operation
in
the
vicinity.
If
this
product
should
cause
harmful
electromagnetic
interference
in
an
indoor
wireless
station
for
identifying
a
mobile
unit,
quickly
change
the
frequency
used
or
stop
emitting
the
electromagnetic
signal,
then
notify
the
store
of
purchase
and
consult
with
them
about
measures
for
avoiding
interference
(for
example,
installing
a
partition
wall).
Besides
that,
if
this
product
should
cause
harmful
electromagnetic
interference
in
a
special
low
‐
power
wireless
station
used
for
identifying
a
mobile
unit,
or
in
an
amateur
wireless
station,
or
some
other

Because
the
2.4GHz
band
frequency
used
in
this
product
overlaps
with
medical
equipment,
microwave
ovens
and
other
industrial
and
scientific
equipment,
as

and
special
low

etc.,
electromagnetic
interference
is
possible.
Before
starting
to
use
this
product,
please
double
check
that
no
indoor
