Electrical power is provided by the aircraft 24V system which keeps the two D-sized
lithium batteries fully charged. When activated, the ELT transmits a swept tone on 121.5 MHz
until battery exhaustion and 440 msec data bursts at 50 second intervals for the first 24 hrs.
Received by the COSPAS-SARSAT satellite system, the data burst contains aircraft
identification data programmed into the beacon and provides location accuracy of
approximately 3 km.
100. The ELT is activated either automatically during a crash (a change in velocity or
deceleration greater than 4.5 fps ±0.5) or manually by selecting the instrument panel remote
switch to ON. Once activated, the ELT may be switched off by selecting either the remote
switch or the switch on the ELT case to the ON position and back to ARM.

NOTE
406 ELTs are individually registered to specific aircraft and are not
interchangeable without first being re-programmed.
NOTE
406 ELTs as installed in this aircraft are not GPS equipped.
