The ARTEX ELT 4000S is an FAA and EASA portable Survival (S) ELT that transmits on 121.5 and 406 MHz. The ELT transmitter is based on the ARTEX ELT 4000 system and represents the latest ELT transmitter technology with a Lithium-free battery in a survival beacon, exempt from TSO C142 and DO-227 approval. The ARTEX ELT 4000S is buoyant and automatically activates when deployed in water. A manual activation switch is also included for land use. An internal GPS (GNSS) will acquire position data for inclusion in the 406 MHz transmission, and a lanyard allows for attachment to a life raft.
