If
required,
the
ELT

To
use
the
ELT
as a
portable
unit
in
an emergency,
remove
the
cover
and
unlatch
the
unit
from its
mounting
base,
The
antenna
cable
is
disconnected by
a
left
quarter-turn
of
the
knurled
nut
and
a
pull. A
sharp
tug
on
the
two
sman
wires
will
break them loose.
Deploy
the
self-contained
antenna
by
pulling
the
plastic
tab marked "PULL
FULLY TO
EXTEND
ANTENNA."
Move
the
switch
to

In
the
event
the
transmitter is activated
by
an
impact, it
can
only be
turned
off
by
moving
the
switch
on
the ELT
unit
to

clear
plastic
reset
button
located
on
the
top
of
the
front
face
of
the ELT
and then
moving

remote
switch

turned
on
from

switch
is
normally
in the
ARMED
position.
Moving
the

the
transmitter.
Moving
the
switch
back
to
the ARMED
position

the
trans-
mitter
only
if
the
impact
switch
has
not
been
activated.
The
ELT
should
be
checked
to
make
certain
the
unit
has
not
been
activated
during
the
ground
check.
Check by
selecting
121.50
MHz
on
an
operating
receiver.
If there
is
an
oscillating
chirping
sound,
the ELT
may
have been
activated and
should be
turned
off
immediately.
This
requires
removal
of
the
access
cover
and moving the
switch
to
OFF, then
press
the
reset
button
and
return
the
switch
to
ARM.
Recheck

A
battery
replacement
date
is marked
on
the
transmitter
to
comply
with
FAA
regulations
the battery
must
be
replaced
on or
before this date. The
batterv
must
also
be
replaced
if
the
transmitter has been
used
in
an
emer-
gency
situation
or
if
the
accumulated
test
time
exceeds
one
hour,
or
if the
unit
has been
inadvertently
activated
for
an
undetermined time
period.
NOTE
If
for
any
reason
a
test
transmission is
necessary,
the
test
transmission
should
be
conducted only
in
the
first five
minutes of
any
hour
and
limited
to
three
audio
sweeps.
If
the
tests
must
be
made
at
any
other
time,
the
tests
should
be
coordinated
with
the
nearest
FAA
tower
or
flight
service
station.
