D3 does not shut off automatically

[awmuhs@aol.com]

My D3 with 1.2.1 update does not shut off after 15 min of inactivity. Settings/inactivity is set to 15 min. What can I do to fix it?

Is the plane stored outdoors? If so, the D3 may be detecting small movements, such as a breeze blowing over the plane. remove it from the aircraft and take it inside. If it still doesn't power down after 15 minutes, you might want to contact Dynon.
