Care
and
Maintenance
Your
CM-S
should
give
you
a
long
period
of
trouble-free
service
if
it
is
connected
to
the
proper
power
source
and
handled
gently.
If
the
monitor
malfunctions,
have
it
checked
by
a
qualified
Radio
Shack
service
technician.
Installation
and
Location
Hints
The
CM-5
has
openings
for
ventilation
purposes,
to
provide
reliable
operation
of
the
monitor
and
protect
it
from
overheating.
•
Install
the
monitor
at
least
four
inches
(0.1
meters)
away
from
the
wall.
•
Never
cover
the
openings
with
cloth
or
other
material.
•
Never
block
the
openings
on
the
bottom
of
the
monitor
by
placing
it
on
a
bed,
sofa,
rug,
etc.
•
Never
place
the
monitor
in
a
built-in
enclosure
unless
proper
ventilation
is
provided.
•
Never
place
the
monitor
near
or
over
a
radiator
or
heat
register.
•
Never
expose
the
monitor
to
rain,
excessive
moisture,
or
excessive
dust.
Moisture
and
dust
create
fire
hazards.
•
Never
place
the
monitor
on
an
unstable
desk,
cart,
or
stand.
Operation
Hints
•
Operate
the
monitor
from
the
power
source
indicated
on
the
back
of
the
cabinet.
Use
of
a
power
source
that
is
not
marked
on
the
monitor
can
cause
monitor
damage
as
well
as
improper
operation.
•
To
ensure
safe
operation,
the
three-pin
plug
(supplied)
must
be
inserted
into
a
standard
three-pin
outlet
which
is
effectively
grounded.
Extension
cords
used
with
the
equipment
must
be
three-wire
and
correctly
wired
to
provide
connec
tion
to
ground.
Improperly
wired
extension
cords
are
a
major
cause
of
fatalities.
The
fact
that
the
equipment
operates
satisfactorily
does
not
imply
that
the
power
point
is
grounded
and
that
the
installation
is
completely
safe.
For
your
safety,
if
in
any
doubt
about
the
effective
grounding
of
the
power
point,
consult
a
qualified
electrician.
Care
and
Maintenance
•
To
prevent
a
fire
or
electrical
shock,
do
not
overload
wall
outlets
and
extension
cords.
•
Adjust
only
those
controls
that
are
described
in
the
"Adjusting
the
CM-5
Display"
section.
Improper
adjustment
of
other
controls
can
result
in
damage
that
will
require
the
services
of
a
technician.
•
Do
not
allow
anything
to
rest
on
the
power
cord.
The
cord
should
not
stretch
across
a
hall
or
any
other
high
traffic
area.
•
Unplug
the
monitor
from
the
AC
outlet
if
it
is
to
be
idle
during
a
weekend,
vacation,
or
other
extended
period
of
time.
•
If
the
same
characters
or
graphics
are
shown
for
a
long
time
with
the
CON
TRAST
and
BRIGHTNESS
controls
set
to
maximum
positions,
part
of
the
screen
may
be
damaged.
Use
these
controls
with
care.
•
To
prevent
electrical
shock
and
other
hazards,
do
not
remove
the
back
cover
of
the
monitor.
•
Do
not
drop
or
push
objects
into
the
cabinet
openings.
Some
internal
parts
carry
hazardous
voltages
and
contact
can
result
in
electrical
shock
or
fire.
•
Never
spill
a
liquid
of
any
kind
on
the
monitor.
If
liquid
is
accidentally
spilled,
unplug
the
unit
and
have
it
checked
by
a
Radio

Cleaning
the
CM-S
Always
unplug
the
monitor
before
cleaning.
Wipe
the
screen
and
cabinet
with
a
soft
cloth.
If
the
screen
requires
more
than
dusting,
use
a
house-hold
window
cleaner
and
a
soft
cloth.
Caution:
Do
not
use
benzene,
thinner,
or
any
volatile
substances
to
clean
the
unit.
Such
substances
can
permanently
mar
the
finish.
Never
leave
the
unit
in
contact
with
rubber
or
vinyl
for
an
extended
period.
Occasionally,
the
internal
parts
of
the
monitor
may
need
to
be
cleaned
to
prevent
a
fire
or
other
damage
caused
by
dust
particles.
It
is
recommended
that
you
take
the
unit
to
a
Radio
Shack
Computer
Center
for
a
yearly
cleaning.
