Tandy Color Computer 3 User Manual

Operation
Power Play
The power-on button is on the
left-rear side of the
computer
case as
you face the keyboard.
Turn
on
the
computer
by
pressing the button
in and
then
releasing
it.
When
you
power-up the computer without
a
cartridge installed,
the
screen
displays a
start-up
message that describes your version and
release
of
Color BASIC followed
by
OK
If this
message doesn't appear,
be sure
the display unit is turned
on
and operational.
If
it is, check
the brightness,
contrast,
and/or fine
tuning
controls
and
be sure
they
are adjusted properly. If
the
message
still
doesn't
appear,
turn
off
the system,
recheck
all
the
connections, and
try
again. (For further
assistance, see
the
"Troubleshooting
and
Maintenance"
section
in this
booklet.)
Get
RESET
...
Go
The RESET
button, located
on the
right-rear
side
of
the
computer
as
you
face
the
keyboard,
lets you stop
a
ROM program and then
restart
it
at
the
beginning
without
turning
the computer
off
and on.
Pressing RESET
doesn't erase
the contents
of
memory like
turning
the computer off
does.
Therefore,
when
you
are
programming in
Color
BASIC,
RESET
stops
execution
but
leaves
your program intact.
A
Turn-off
To
turn
off
your computer, press the
power button
on
the
left-rear
side
of
the
computer case.
If
you
turn
off
the
computer
and
then
decide
you
want
to
use it
again,
always
leave
it
off
for at least
15
seconds before
turning
it on.
The
computer's
power
supply
needs
this
much time to
discharge
its stored
energy
before you start
it
up
again.
Keep
in
mind that turning off
the
computer erases all RAM-based
programs
and
data
from memory.
If
you
want
to save data or a
program,
do it before
you
turn
off the computer.

"Using the
Cassette Recorder.")
