That's A Switch - Tandy Color Computer 3 Manual

Installation
That's a
Switch
Not only
is
your
computer a computer,
it's
also
a miniature
television
broadcasting
station.
A
built-in
television interface (called
an
RF
Modulator)
sends
out
a
VHF
signal that
your
set
"sees"
the
same
way
it
"sees" a network
television
show.
The Antenna
Switchbox
that
comes
with
your
computer
lets
you
select either television-station
reception
or
computer
input without
having
to
connect
and
disconnect
the
computer
every time the
television
is
used. This
Antenna Switchbox
consists
of
a
short section
of
twin-lead cable,
two screw
terminals, a coaxial connector,
and
a
slide switch.
We
suggest you
attach the
Switchbox
to
the
back
of
your
TV
set
(see Figure
1).
Select
a smooth,
flat
surface on the
back
of
the
television that
is
well
within
reach
of
the
antenna
cables.
Wipe
off
any
dust,
dirt,
or
grease
from
the
mounting
surface;
then
remove
the
backing from the
double-sided adhesive tape
on
the
Switchbox. Press
the
Switchbox
against the
back
of
your
TV
cabinet
in
the desired
location.
