The equipment
described
in
this manual
generates
and
uses radio-
frequency energy. If
it is
not installed
and used
properly--that is, in
strict
accordance with Apple's instructions-it
may cause interference
with
radio
and television
reception.
This eguipment
has been tested
and complies
with
the
limits for a Class
B
computing
device in accordance
with the specifications
in Subpart
J,
Part t5,
of FCC rules.
These
rules
are designed
to
provide
reasonable
protection against such
interference in a residential
installation.
However,
there is no
gurrantee that the interference
will not occur in
a
Particular
installation,
especially
if a
"rabbit-ear"
television
antenna is
used.
(A
rabbit-
ear antenna is
the telescoping-rod
type usually found
on television
receivers.)
You can
determine
whether
your
comPuter
is causing interference
by
tuming it
off. If the
interference stops, it
was
probably
caused
by the
computer
or its
peripheral devices. To further
isolate the
problem,
disconnect the
peripheral
devices
and their inPut/outPut
(I,/O)
cables
one
at a time. If the
interference stops, it
was caused by either
the
peripheral
device or the
VO
cable. These devices
usually require
shielded I/O
cables.
For
Apple
peripherd devices,
you
can obtain
the
proper shielded cable
from
your
authorized
Apple dealer.
For non-Apple
peripheral devices,
contact the manufacturer or dealer
for assistance.

If
your
computer
does cause interference
to radio or television
reception,
you cnn try to correct
the
interference
by using
one
or
more of the
following measuresi
r Tum the television
or radio antenna
until the interference
stops.
r Move the computer
to one side or the
other of the television
or radio.
r Move the computer
farther away from
the television
or radio.
r Plug the computer
into an outlet
that is on a different
circuit than
the
television or
radio.
(Ihat
is, make certain
the computer and
the radio
or
television set
are on circuits controlled
by different
circuit breakers
or
fuses.)
r Consider installing
a
rooftop
television antenna
with a coaxial
cable
lead-in between
the antenna and
television.
If necessary,
consult
your
authorized Apple
dealer or an
experienced
radioltelevision
technician for additional
suggestions.
