Page 9: Introduction, Description And Operation
ARTEX AIRCRAFT SUPPLIES, INC. 570-1600 Introduction, Description and Operation Basic Information This manual describes the operation, installation and maintenance of the Artex models ME406 and ME406HM emergency locator transmitters (ELTs). The information is provided to ensure initial and continued airworthiness. Information presented in this manual is accurate at time of printing, but is subject to change. -
Page 10: Description
ARTEX AIRCRAFT SUPPLIES, INC. 570-1600 Description The ME406 and the ME406HM are type AF (automatic fixed) beacons. The ME406HM also features an additional 5 axis G-switch module that allows the ELT to be activated in any of six axes. These 5 auxiliary “G” switches are a “non-TSO function” as described in FAA Notice 8150.3. -
Page 11: Programming
ARTEX AIRCRAFT SUPPLIES, INC. 570-1600 • COSPAS-SARSAT T.001 and T.007 • 47 CFR Part 87 (FCC requirements) Note: 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. -
Page 12: Operation
ARTEX AIRCRAFT SUPPLIES, INC. 570-1600 Figure 1 – ME406 Installed View 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. -
Page 13: Accuracy
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. -
Page 14: Figure 2 - Elt Front View
ARTEX AIRCRAFT SUPPLIES, INC. 570-1600 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. -

ARTEX AIRCRAFT SUPPLIES, INC. 570-1600 Mount Audio Indicator (“buzzer”) An audio indicator is required for TSO-C126 approval. The indicator, i.e., “buzzer” (P/N 452- 6505) is powered by the ELT and, therefore independent of the aircraft power system. When the ELT is activated, the buzzer ‘beeps’ periodically. The time between pulses lengthen after a predetermined transmitter ‘on’... -
Page 27: Harness Wiring - Remote Switch End
ARTEX AIRCRAFT SUPPLIES, INC. 570-1600 A ground may be connected at either the ‘panel end’ or the ‘ELT end’ of the harness, but both locations should not be grounded. This prevents current flow thorough the shield from other equipment (ground loop). A convenient ground connection is pin 9 of the remote switch connector. -
