Using
the
PLB
afloat
The
PLB
is
totally
waterproof
but
is
not
designed
to
operate
when
floating
on
the
surface
of
the
water.
It
is
buoyant
and
will
not
sink
if
dropped
into
water.
If
possible
keep
it
out
of
the
water
when
in
use.
Place
it
high
up
on
your
Personal
Flotation
Device
(PFD),
lifejacket,
or
chest
and
clear
of
any
wave
wash.
Any
trapped
water
in
the
Antenna
Well
should
be
removed
periodically
by
shaking
the
PLB.
Aboard
a
liferaft
The
principle
is
to
give
the
PLB
as
clear
a
view
of
the
sky
as
possible
whilst
keeping
it
flat.
If
the
raft
is
full,
it
may
be
necessary
to
elevate
the
PLB
or
hold
it
outside
the
liferaft
canopy.
Attach
the
lanyard
to
your
clothing
so
in
the
event
of
separation
from
the
liferaft
the
PLB
will
stay
with
you.
Aboard
ship
Operate
the
PLB
on
deck;
position
it
to
have
the
clearest
possible
view
of
the
sky.
Lay
it
flat
on
the
deck
with
the
antenna
pointing
up
towards
the
sky.
Aviation
The
PLB
is
not
designed
for
activation
aboard
an
aircraft
although
they
are
often
used
as
an
additional
carry-off
safety
device.
Take
care
not
to
place
the
PLB
in
the
shadow
of
the
aircraft.
Lay
it
on
a
flat
surface
with
the
antenna
pointing
up
towards
the
sky
and
with
the
maximum
amount
of
sky
possible
in
view.
Vehicles
Because
of
the
shielding
effect,
the
PLB
probably
will
not
operate
effectively
when
inside
a
vehicle.
It
is
best
placed
outside
on
the
roof,
hood
or
trunk.
