It
is
recom-
mended
that
you
do
not
use
needle-nosed
pliers
to
disconnect
connec-
tions

these
can
damage
the
soft
metal
or
plastic
parts
of
the
connec-
tors.

Precautions
Computer
components
and
electronic

can
be
damaged
by
discharges
of
static
electricity.
Working

be
extremely
dangerous.
Follow
the
guidelines

wear
a
grounded
wrist
strap
when
you

electricity
by
touching
the
bare
metal
chassis
of
the
unit
case,
or
the
bare
metal
body
of
any
other
grounded
appliance.
·
Hold
electronic
circuit
boards
by
the
edges
only.
Do
not
touch
the
com-
ponents
on
the
board
unless
it
is
necessary
to
do
so.
Don’t
flex
or
stress
the
circuit
board.
·
Leave
all

the
static-proof
packaging
that
they
shipped
with
until
they
are
ready
for
installation.
