2.1 Operational Frequencies
406 ELT transmits on 406.037 MHz which is monitored by the Cospas/Sarsat system.
2.2 Out Put Power
The 406.037 will transmit a 5W pulse (520ms) every 50 ± 2.5 seconds for up to 110 hours. An
internal battery clock will inform the pilot during normal self-test if the available transmit power
drops below 36 hours.
2.3 Activation
The pilot has control of a remote that has been installed on the aircraft instrument panel. The
remote is equipped with an ON, ARM, TEST/RESET switch, a tri-color (red/yellow/green) LED,
and an aural alert. With this remote you can run the ELT self-test, GPS Self-Test or activate the
unit in flight if conditions warrant. The unit’s LED will flash green every
½ second and the aural
alert will go off every 5 seconds.

Each flash has duration of
½ second. See Trouble shooting guide Appendix D for details.
In the event of a crash the unit has an automatic activation accelerometer or G-Switch. With a
change of 4.5ft./sec/ (2.3G) the accelerometer senses the dramatic decrease in speed and
activates the 406 transmitter. In the case of a helicopter unit it has a multi-axis accelerometer to
compensate for the different attitudes of flight that might occur.
When the unit is activated by the G-Switch an aural alert (85db) will go off in the cockpit. . The
406 signal can be reset by pressing the TEST/RESET switch. The beacon will automatically
return to an ARM state. The remote switch or the control switch mounted on the front of the
beacon can be used for these functions.
