• If this error code persists there may be a problem with the antenna installation.
This can be checked with a VSWR meter. Check the antenna for opens, shorts,
resistive ground plane connection.
4 Flashes
Low power detected. Occurs if output power is below about 33 dBm (2 watts) for
the 406 signal or 17 dBm (50 mW) for the 121.5 MHz output. Also may indicate
that 406 signal is off frequency. For this error code the ELT must be sent back for
repair or replacement.
5 Flashes
Indicates that ELT has not been programmed, or is incorrectly programmed. Does
not indicate erroneous or corrupted programmed data.
6 Flashes
Indicates that the G-switch loop between pins 5 and 12 at the D-sub connector is
not installed. ELT will not activate during a crash.
• Check that the harness D-sub jumper is installed by verifying less than 1 ohm of
resistance between pins 5 and 12.
7 Flashes
Indicates that the ELT battery has too much accumulated operation time (> 1hr,
see below). Battery may still power ELT; however, it must be replaced to meet
FAA specifications. May also indicate damage to the battery circuit.
