CHEROKEE 180 SECTION III
exceeds
one hour. The
replacement
date
is marked
on
the transmitter
label.
The
unit
has
a three
position
selector switch
placarded
"OFF,"
"ARM"
and
"ON." The "ARM"
position is provided
to set the
unit to
the automatic
position
so that
it
will
transmit only after
impact
and
continue
to transmit
until
the
battery power is drained
to depletion
or
the switch
is
manually
moved
to the
"OFF"
position.
The "ARM"
position
is
selected
when the
locator is installed at
the
factory
and
should
remain
in
that
position
whenever the unit
is installed
in
the
aircraft.
The "ON" position
is
provided so
the unit can
be
used as
a
portable
transmitter
or in
the event the
automatic
feature
was not
triggered
by
impact or to
check the
function
of the transmitter
periodically.
The "OFF" position
is provided
for
the
purpose of changing the
battery
or
if
used as
a
portable
transmitter
or rearming
the unit
if it
should
be
activated
for
any reason.
NOTE
If
the
switch
has been
placed
in
the
"ON" position
for
any
reason,
the
"OFF" position has
to
be selected
before
selecting "ARM." If "ARM"
is selected
directly from
the
"ON" position
the transmitter will
continue
to transmit
in
the
"ARM"
position.
Attached
to the
unit
is
a
portable
antenna,
provided
so
that
the
locator may be
removed
from
the aircraft,
in
case
of
an
emergency,
and
used as a
portable
signal transmitter.
The
locator
should
be
checked
during
the Ground Check
to make
certain
the unit
has not been
accidently
activated.
Check by
tuning a
radio
receiver to
121.5
MHz.
If
you
hear
an
oscillating
audio
sound
the
locator
may
have been activated and should be turned
off
immediately.
Reset
to
"ARM"
position
and check again to
insure
against
outside
interference.
