N. Digital Message Verification – Item 5g
1) Activate the ELT by placing the control switch in the “ON” position.
2) Allow the ELT to transmit for 15 to 30 seconds, but not more than 40 seconds.
3) Set the 453-1000 ELT Test Set (ETS) beacon reader to receive and decode the ELT digital message.
Refer to the ETS operating manual (570-1000) for ETS operating instructions and additional details.
NOTE: A beacon reader equivalent to the ETS may be used, provided it is capable of
receiving and decoding the 406 MHz digital message.
4) Deactivate the ELT and read the test message broadcast at “turn-off”. Message examples are shown
in Figure 9 Short and Long 406 MHz Message Examples.
a) The test message broadcast by the ELT at “turn-off” contains all the information in an actual
distress message, except there is a special digital prefix that informs COSPAS-SARSAT satellites
to ignore the message.
b) The left hand example in Figure 9 Short and Long 406 MHz Message Examples is an ELT
programmed for “User Protocol ELT with Serial Number”, with a test Hex ID. The right hand
example is an ELT programmed for “Standard Location Protocol ELT with Serial Number”.
c) Actual messages will vary depending on the protocol and information programmed into the ELT.
d) If the ELT is programmed with a location (long message) protocol and disconnected from the
ELT/NAV Interface, the message will indicate “Position Invalid” in lieu of position data, as shown
in the right hand example in Figure 9 Short and Long 406 MHz Message Examples.

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 37.

O. ELT Reset Check – Item 5h
1) Place the ELT control switch in the “ON” position.
2) Return the switch to the “OFF” position.
3) If the ELT is working properly, the LED will stay on for approximately 1 second and then turn off. If a
series of flashes are displayed, refer to Table 6 on page 37.
NOTE: A 5-flash error indication will occur if the ELT is programmed with a location protocol,
since no navigation input data is present.
