Safety
Use
the
following
safety
guidelines
to
help
protect
yourself
and
the
N37B
.
•
Do
not
attempt
to
service
the
N37B
yourself.
Always
follow
installation
instructions
closely.
•
Be
sure
that
nothing
rests
on
the
AC
adapter's
power
cable
and
that
the
cable
is
not
located
where
it
can
be
tripped
over
or
stepped
on.
•
Do
not
cover
the
AC
adapter
with
papers
or
other
items
that
will
reduce
cooling;
also,
do
not
use
the
AC
adapter
while
it
is
inside
a
carrying
case.
•
Use
only
the
AC
adapter,
power
cord,
and
batteries
that
are
approved
for
use
with
this
N37B
.
Use
of
another
type
of
battery
or
AC
adapter
may
cause
risk
of
fire
or
explosion.
•
If
you
use
an
extension
cable
with
the
AC
adapter,
ensure
that
the
total
ampere
rating
of
the
products
plugged
in
to
the
extension
cable
does
not
exceed
the
ampere
rating
of
the
extension
cable.
•
When
you
move
the
N37B
between
environments
with
very
different
temperature
and/or
humidity
ranges,
condensation
may
form
on
or
within
the
N37B
.
To
avoid
damaging
the
N37B
,
allow
sufficient
time
for
the
moisture
to
evaporate
before
using
the
N37B
.
•
When
you
disconnect
a
cable,
pull
on
its
connector
or
on
its
strain
relief
loop,
not
on
the
cable
itself.
As
you
pull
out
the
connector,
keep
it
evenly
aligned
to
avoid
bending
any
connector
pins.
Also,
before
you
connect
a
cable
make
sure
both
connectors
are
correctly
oriented
and
aligned.
