Power Play; Get Reset; A Turn-Off - Tandy Color Computer 3 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. (See "Using
the
Cassette Recorder.")
