DESCRIPTION, OPERATION, INSTALLATION AND MAINTENANCE MANUAL
ME406P (453-6611)
(a) It is possible the primary G-switch or one of the auxiliary G-switches could activate the
ELT in either a fixed or rotor wing aircraft as the result of severe maneuvers or a very
hard landing.
(b) To take the ELT from an “ACTIVE” state back to an “INACTIVE” state, a reset must
occur. See SUBTASK 25-62-31-870-005 on page 28.
(6) A warning buzzer is required under C126 TSO approval. The buzzer is powered by the ELT and
therefore not dependent upon the aircraft battery for operation. It is not designed to operate
continuously, but sounds at predetermined intervals and runs for shorter periods toward the
end of ELT battery life.
(7) When operating in portable mode, the functional differences include:
(a) Activation via the local ELT switch only. The G-switch is disabled when the remote
switch harness plug is removed.
(b) An active ELT is indicated by the flashing LED on the ELT front panel.
(c) The portable antenna must be connected to the ELT.

C. Manual Activation
(1) The ELT may be manually activated by placing either the remote switch or the ELT local
switch in the “ON” position.
NOTE: As long as the cockpit remote switch and the ELT local switch are in the ARM (off)
positions respectively, the ELT will automatically activate on impact.

D. Portable Operation
(1) See Figure 8. ME406P Portable Configuration on page 28.
(2) Disconnect the antenna coax cable and remote switch harness plug.
(3) Open the Velcro strap, lift the front of the ELT and slide it out of the mounting tray.
(4) Attach the portable antenna to the ELT BNC male connector.
(5) Move the toggle switch to the “ON” position to activate the ELT.
(6) Maintain the ELT in an upright position, such that the antenna is vertical, for optimum
performance.
