MANUAL
MAINTENANCE
Maintenance
on
the
ELT
is
normally
limited
to
replacing
the
battery.
The
following
is
a
list
of
the various conditions
which
warrant
battery
replacement.
a.
Visual
inspection
shows
signs
of
leakage,
corrosion
or
unsecured
leads.
b.
Elapsed
replacement
date noted
on
the
battery
case
(this
date
represents
50%
of
the
useful
life
of
the
battery).
NOTE:
The
useful
life
of
the
battery
is
the
length
of
time
which
the
battery
may
be stored without
losing
its
ability
to
continuously
operate
the ELT for
48
hours.
c.
Afteranyemergency
use.
d.
Afteronecumulative
hourof
use.
e.
Afteroperationof
unknownduration.
f.
If the
transmitter
is
stored
in
an area
where the
temperature
is
normally
above
38"C
(100"F),
the
battery
life
will
be
shortened.
CAUTION:
Avoid
storage
of
batteries
at
temperatures
in
excess
of
55"C
(130"F).
The
information
on
battery
life
an
replacement
is
included
in the
data furnished
with each
ELT,
and is
usually
placarded
on
the
battery.
NOTE:
Replacement
batteries
should be
obtained
only
from
ELT
manufacturers,
airplane
manufacturers
or
other
acceptable
suppliers,
since the condition
and
useful
life
of over-the-counter
batteries,
such
as
those
sold
for
flashlights,
portable
radios,
etc.,
are
usually
unknown.
CAUTION:
The ELT
switch
should
not
be
turned
ON
unless
the
ELT
is
connected
to
its associated
antenna
or a
50-ohm
dummy
load.

h.
The
new
replacement
date
should
be
marked
on
the
ELT in
a
visible
area.
This
will
aid
in
future
inspections
of
the
ELT.
This date
is
50%
of
the
useful life of the
battery
as
defined
by
the
battery
manufacturer.
