(10) Slide the mounting frame cap into place over the mounting tray and protective top cover.
(11) Secure the mounting frame cap to the mounting tray with the thumbscrews and tighten them
to no more than 18 lb-in (203 N•cm).
(12) Tie up excess slack in the harness and coax cable, such that they form drip loops and there is
enough slack, approximately 5 in. (127 mm), to allow the mounting frame cap to be easily
pulled back.
NOTE: Steps 1 through 11 are applicable any time the ELT has been removed and
undergoes reinstallation. Step 12 is only applicable at initial installation or if the
wiring or coax cable has been disturbed.

(1)
Test the ELT installation in accordance with the requirements of SUBTASK 25-62-13-750-011

continuously upon ELT activation. If the light fails to start flashing, recheck the
interface wiring and connections between the ELT and the cockpit remote switch.

Comply with the GPS/FMC manufacturer’s written post-installation checkout instructions and
verify connection to the C406-N Series ELT has not caused any degradation in GPS/FMC

NOTE: For all “live” RF testing of the 406 MHz message output, only the “test message”
transmitted at ELT turn-off is required to verify C406-N functions. See SUBTASK 25-
