The reader is now ready to receive and decode the message. Select “measure”
from “Avionic Tools” screen as shown in Figure 3. The screen will display
“Waiting for Data” as shown in Figure 4 until a valid ELT transmission is received.
Perform a “Self Test” of the ELT by turning the ELT local or remote switch from
“OFF/ARMED” to “ON” for no more than 3 sweeps of the 121.5/243 MHz signal
and then switch back to “OFF/ARMED”. If the received data is invalid, then
“Message Error!” will be displayed. This may indicate excessive distance from
the ELT antenna if testing externally. 0-30 feet distance from the ELT antenna is
recommended, although distances up to 50 feet are possible (as allowed). The
ELT internal 406 MHz oscillator may also need to warm-up. Repeat the ELT test if
necessary.
