Hello Yono,

Thanks for this information.  One the battery voltage gets down to about
3.6V (think that's the value...), AO-91 will go automatically into safe
mode.  The values of "MIN" in the telemetry logs will help to tell a more
complete picture.  It's reporting as low as 3.31V now.    So yes, it's
behaving as designed and engineered!

73,

Mark L. Hammond [N8MH]
AMSAT Director and Command Station
