Installing
the
TV/Game
Switch Box
Your TV/Game
Switch Box
allows
you
to
change from
television
viewing
to
video game
play
and
back by simply
sliding a switch.
The
switch box
is
easy
to
install.
Find the
picture that
looks the
most
like
the back
of
your
TV
set
and
follow those
instructions. All
you need
is
a screwdriver.
If
Your
Television Has Four
Screws
Only:
A. Disconnect the twin-lead wire
from your
television
and
attach
it
to the
ANTENNA
screw
terminals
on
the
TV/GAME
Switch Box.
B.
Connect
the twin-lead
wire
from
the
TV/GAME
Switch Box
to
the
VHF
antenna
terminals
on
your
television
set.
If
you do
not
have
a flat
twin-lead
antenna
wire,
you may
need
to
buy an "impedance-matching
transformer"
(also called a "balun
coil").
It is
also available
at a
nominal
cost
from your
local
TV
and
stereo
stores.
By
attaching a
TV/GAME
Switch
Box
to
each
television
in
your
home, you
can
easily
move
your
ATARI 7800
ProSystem from
room
to
room.
Extra
TV/GAME
Switch Boxes
may
be purchased
separately.
If
Your
Television
Has
a
U-Shaped
Slider or a
Slide
Switch:
A.
Move
the
U-shaped
slider to
make
connection
between
the
two
screws. Or, push
the
slide
switch
to
the
side
marked "300
ohm"
or
"300 Q
."
B:
If
you have
a
round antenna
cable:
Disconnect
the cable
from
your
television.
Screw
the cable
into
the
impedance-matching
transformer.
Attach the impedance-
matching transformer
to the
ANTENNA
screw
terminals
on
the
TV/GAME
Switch
Box.
Or
if
you have
a
flat
twin-
lead antenna
wire:
Disconnect
it
from
the
televi-
sion
and
attach
it
to the
ANTENNA
screw
terminals
on
the
TV/GAME
Switch
Box.
C.
Connect
the short twin-lead
wire from the
TV/GAME
Switch
Box
to the
VHF
antenna
ter-
minals
on your
television
set.
