Ameri-King AK-451-ELT - Manual (Page 76)

WARNING
Do not allow test duration to exceed 5-10 seconds. A false alarm may be
generated.
Any time the ELT is activated, it is transmitting a 121.5 MHz and 243.0 MHz
distress signal. If the ELT operates for approximately 50 seconds, a “live” 406
MHz distress signal is transmitted and is considered valid by the Cospas-Sarsat
satellite system.
Any time that the ELT Main Switch is lifted and flipped from “OFF” to “ARM”,
a 406 MHz self test signal is transmitted (after 25 seconds), however it is
specially coded as a “self test” signal that is ignored by the COSPAS-SARSAT
satellites.
Note: Press RESET anytime to turn off unwanted transmission.
