6. Plug modular cable into remote and install switch into
instrument panel with (4) mounting screws the split
panel and the “Horseshoe” bracket (from behind unit).
Tighten the two (2) switch retaining nuts.
7. Record the next remote battery replacement date on
one of the adhesive labels supplied and apply to the
ELT in a readily visible location.

ARTEX ME--406
The Artex ME--406 remote ELT switch (Figure 39--18)
is located on the Instrument Panel. The location is de-
termined by optional equipment per sales order. The
ELT is located in the tailcone and is accessible by re-
moving radio access panel on right or left side of aircraft
tailcone. The ELT antenna is located on top of tailcone
underneath the fiberglass dorsal fin.
Refer to the Artex web site www.artex.net for latest in-
formation and updates to the information provided in
this service & maintenance manual regarding the Artex
ME--406 ELT.
In a crash, an acceleration activated crash sensor (G--
switch) turns the ELT “ON” automatically when a
change in velocity (deceleration) of 4.5 fps
±
0.5 fps is
sensed. Activation is also accomplished by the cockpit
instrument panel mounted remote switch or local
switch on the ELT. To deactivate the ELT, set either
switch to “ON” position and the back to “ARM.”
The ELT does not have an “OFF” position. A jumper be-
tween two pins on the front of the D--sub connector
must be in place for the “G” switch to activate the unit.
The jumper is installed on the mating half of the connec-
tor so that when the connector is installed, the beacon
is armed. This allows the beacon to be handled or
shipped without “nuisance” activation (front connector
removed).
NOTE:
The ELT can still be manually activated using the
switch on the front of the ELT. Care should be
taken when transporting or shipping the ELT not
to move the switch or allow packing material to
become lodged and toggle the switch.
Self Test Mode
Upon turn--off, the ELT automatically enters a “Self--
Test Mode.” The ELT transmits a 406 MHz test coded
pulse that monitors certain system functions before en-
tering the “ARM”ed mode. The 406 MHz test pulse is
ignored by any satellite that receives the signal, but the
ELT uses this output to check output power and correct
frequency. If the ELT is left activated for approximately
50 seconds or greater, a distress signal is generated
that IS accepted by one or more SAR satellites. There-
fore, when the self--test mode is required, the ELT must
be activated then, returned to “ARM” within about 45
seconds, otherwise a live distress message will be
transmitted.
NOTE:
All activations of the ELT should be kept to a
minimum. Local or national regulations may limit
testing of the ELT or special requirements or
conditions to perform testing. For the “Self--
Test,” it is recommended that the ELT be “ON”
for more than 5 seconds during the first 5 min-
utes after the hour.
In addition to output power of the 121.5/406 MHz sig-
nals and 406 MHz frequency, other parameters of the
