•
In
order
to
provide
strain
relief
and
to
avoid
transmitting
excessive
vibration
to
the
modem
during
installation,
all
cables
connected
to
the
MTX
‐
3G
‐
JAVA
Terminal
must
be
secured
or
clamped
immediately
adjacent
to
the
modem's
connectors.
•
To
protect
the
power
supply
cables,
and
in
order
to
comply
with
fire
safety
requirements,
when
the
unit
is
powered
from
a
battery
or
a
high
current
supply,
a
fast
1.25A
fuse
should
be
connected
in
line
with
the
positive
supply.
•
Any
incompatible
components
or
products
must
not
be
connected

SIM card precautions
Before
handling
the
SIM
card
in
your
application,
ensure
that
you
are
not
charged
with
static
electricity.
Use
proper
precautions
to
avoid
electrostatic
discharges.
•
When
the
SIM
card
hatch
is
opened,
the
SIM
card
connectors
lie
exposed
under
the
SIM
card
holder.
Caution!
Do
not
touch
these
connectors!
If
you
do,
you
may
release
an
electrical
discharge
that
could
damage
the
modem
or
the
SIM
card.
•
When
designing
your
application,
the
SIM
card’s
accessibility
should
be
taken
into
account.
We
always
recommend
that
you
have
the
SIM
card
protected
by
a
PIN
code.
This
will
ensure
that
the
SIM
card
cannot
be
used
by
an
unauthorized
person.
8.4
Antenna precautions
If
the
antenna
is
to
be
mounted
outside,
consider
the
risk
of
lightning.
Follow
the
instructions
provided
by
the
antenna
manufacturer.
•
Never
connect
more
than
one
modem
to
a
single
antenna.
The
modem
can
be
damaged
by
radio
frequency
energy
from
the
transmitter
of
another
modem.
•
Like
any
mobile
station,
the
antenna
of
the
modem
emits
radio
frequency
energy.
To
avoid
EMI
(electromagnetic
interference),
you
must
determine
whether
the
application
itself,
or
equipment
in
the
application’s
proximity,
needs
further
protection
against
radio
emission
and
the
disturbances
it
might
cause.
Protection
is
secured
either
by
shielding
the
surrounding
electronics
or
by
moving
the
antenna
away
from
the
electronics
and
the
external
signal
cable.
