The ELT is reporting low output power due to a bad load or faulty unit. The manual's first action is: “1) Terminate antenna cable at antenna connection end w/50Ω load. Repeat self-test. If error clears, proceed to step 3. 2) Terminate ELT output w/50Ω load. Repeat self-test. If error persists, return to factory for servicing – cannot field repair. If error clears, replace antenna cable. 3) Check coax cable and connectors for shorts and opens, bad center pin. Disconnect, then reconnect cable. Repeat self-test. 4) Check antenna ground for low resistance (should be <100 m Ω) 5) Antenna should be 3' away from any vertical metal. 6) Have antenna checked by factory.”
