Connecting the
Video
Display
and Keyboard:
1.
Connect the power
cord from the Video
Display to
a source
of 120
volts, 60
Hz
AC
power. Note that one prong
of the
AC plug
is wider
than
the other
—
the wide prong
should
go into the
widest

NOTE: If
you use an AC extension
cord,
you may
not
be able to
plug
the Display's power
cord in.
Do not
attempt
to force
this
wide prong into the
extension

into
the
CTR-41
as
described
in
the
Manual.
Or
make

Connect
the
short
cable
(DIN
plug
on
one
end
and
3
plugs
on
the
other)
to the
TAPE
jack
on the
back
of
the
Keyboard
Assembly.

to
the
CTR-41.
A.
Connect
the
black
plug
into
the
EAR
jack
on
the
side
of
the
CTR-41.
This
connection
provides
the
output
signal
from
the
CTR-41
to
the
TRS-80
(for
loading
Tape
programs
into
the
TRS-80).
Connect
the
larger
gray
plug
into
the
AUX

grams
from
the
TRS-80
onto
the
CTR-41
's tape.
Also, plug
the
Dummy
Plug
(provided
with
the
CTR-41)
into
the MIC
jack
(this
disconnects
the
built-in
Mic
so it
won't
pick-
up
sounds
while
you
are loading
tapes).
NOTE:
Be
sure
you
always
use
the
Dummy
Plug
when
loading
programs
onto
tape
(Recording).
B
Dummy Plug
C. Connect
the
smaller
gray plug
into
the
REM
jack
on the
CTR-41.
This
allows
the
TRS-80
to
automatically
control
the
CTR-41
's motor
(turn
tape
motion
on
and off
for
recording
and playing
tapes).
Notes On Using
The Recorder
There
are a number of things
you should
be
aware of
as
you use
the
Cassette

of this
will
be covered in
greater
detail
in Chapter
9 . . .
but some of
you can't
wait till
then
.
.
. can
you!)
