Note 2: Press RESET anytime to turn off unwanted transmission.
*WARNING Do not allow ELT On test duration and G Switch 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.
**WARNING
Any time that the ELT Main Switch is lifted and flipped from “OFF” to “ARM”, a 406 MHz self test burst is transmitted
(after 25 seconds),however it is specially coded as a “self test, Bit reversal” signal that is ignored by the COSPAS-SARSAT satellites
