ARTEX AIRCRAFT SUPPLIES, INC. • • Note: 570-1600 COSPAS-SARSAT T.001 and T.007 47 CFR Part 87 (FCC requirements) Per FCC regulations 47 CFR § 2.902, the ELT is tested per “Verification” method, the FCC does not issue certificates for ELTs. The FCC identifier grantee code for Artex is H4K. Programming 1.5 The ME406 or ME406HM is pre-programmed at the factory using a short message format.
PAGE 12
ARTEX AIRCRAFT SUPPLIES, INC. 570-1600 Figure 1 – ME406 Installed View 1.6 Operation In the event of a crash, the ME406 or ME406HM activates automatically (automatic fixed “AF” configuration), and transmits the standard swept tone on 121.5 MHz lasting until battery power is gone. This 121.5 MHz signal is mainly used to pinpoint the beacon during search and rescue operations.
PAGE 13
ARTEX AIRCRAFT SUPPLIES, INC. 570-1600 In addition, for the first 24 hours of operation, a 406 MHz signal is transmitting at 50-second intervals. This transmission lasts 440 ms and contains identification data programmed into the beacon and is received by COSPAS-SARSAT satellites. The transmitted data is referenced in a database (maintained by the national authority responsible for ELT registration) and used to identify the beacon and owner. 1.6.
PAGE 14
ARTEX AIRCRAFT SUPPLIES, INC. NOTE: Any time the ELT is activated, it is transmitting a 121.5 MHz distress signal. Therefore, all activations of the ELT should be kept to a minimum. Local or national regulations may limit testing of the ELT or impose special requirements or conditions to perform testing. For the “Self-Test,” Artex recommends the ELT be “ON” for no more than 5 seconds. Testing should occur during the first 5 minutes after the hour.
