precautions
relevant
to
the
country
of
operation.
As
a
general
rule,
protective
overalls,
gloves
and
goggles
should
be
worn

chemical
agents,
but
different
countries
may

Anti-static
precautions
The
electronics
section
of
the
SMARTFIND
NAVTEX
is
sensitive
to
electrostatic
discharge
(ESD)
which
can
cause
immediate
or
hidden
long
term
damage.
It
is
important
that
the
PCB
is
only
handled
under
suitable
anti-static
conditions.
Ideally,
a
fully
grounded
workstation,
which
has
conductive
surfaces
to
avoid
the
build
up
of
static
charge,
should
be
used.
As
a
minimum,
the
operator
must
be
connected
to
a
good
earth
point
through
a
resistance
of
1MOhm.
This
is
usually
achieved
by
wearing
a
suitable
wrist
strap.
