(d) If the ELT is programmed with a location (long message) protocol and disconnected
from the aircraft navigation system or interface device, the message will indicate
“Position Invalid” in lieu of position data, as shown in the right hand example in "Figure
11. Short and Long 406 MHz Message Examples on page 41.
(5) Repeat the activation and deactivation cycle if the ETS fails to read the message on the initial
try. The 406 MHz oscillator may not be warmed up. If continued attempts to read the
message fail, check for self-test error codes and refer to Table 6 on page 43.
