IntrodJction
Most television
sets
In
current use
will
be suitable
for
the OL provided they are able
to
receive 625 line UHF transmissions, ie. BBC2 and Channel
4.
Locate the aerial socket
at
the back
of
your
TV
and remove the aerial cable that may
be plugged into It
If
your
set
has more than one
socket,
use the one labelled UHF
or
625.
Plug
in
the OLs aerial lead. Use the end that looks similar
to
the onginal aerial
plug, and plug the other end into the socket marked UHF
on
the back
of
the computer.
Plug the power supply into a mains socket and switch
on.
Remove any cartridges from
the Microdrive
slots
and push the small power supply connector into the three pin plug
marked
POWER
on the back
of
the OL. The yellow power light below the
F5
key
should
now be glowing and your
set
up should look
like

OL
When the computer has been
on
for a while, the case above the Microdrives
will
feel
warm; this
is
quite normal. The OL has no on/off switch but can be turned off by
unplugging the power supply connector. Remember that any program
or
data
in
the
machine will
be
lost when
it
is turned off and should first be saved on a Microdrive
cartridge
(for
details
of
how
to
do
this see the Beginner's Guide and Concept sections).
If
the OL
is
not going
to
be used for a while you should also switch the power supply
off
at
the mai
ns.
TUNING
IN
The display signal
to
the television
set
is
near channel
36.
If
your
set
has continuous
tuning, tune
to
channel
36.
If
your television has push buttons, choose
an
unused button
and tune this
to
the computer's signal.
You
may need
to
consult your dealer or the
TV
instruction manual
to
find out how
to
do
this.
Once you are correctly tuned
in
you should see the copyright screen.

The OL doesn't use television sound because
it
has
its
own internal loudspeaker.
You
can
turn
the
television
volume
down
if
you
wish.
