My radio shut down, the monitor said lost connection.
It had a bit of a strange shut down.
Now when I shut down I don't see the warning message about low power anymore.
But the radio seems to be working just fine other wise.

Check your DC connections?

I am not sure checking my DC connections would effect the shut off warning showing as it used to.
But everything seems ok otherwise.

A high resistance connection will generate the low voltage message

Yes, as your p/s bleeds off voltage, it will drop below 9.5 VDC and that will trigger the message.

As I understand it, it's not recommended to shut off DC power without powering down the radio first. Is that what you're doing?

While it is not the recommended way to shut down the radio, there are not any reports of corrupted file systems by doing it.  If the radio is not shut down by using the power button and the power is shut off or disconnected, any possible file corruption is corrected by the journaling file system and a fsck is run at the next boot. 

And you will get this error when the radio is powered down normally and then you shut down your power supply.  In this state, the radio is still monitoring the input voltage level and if the voltage drops below 9.5 VDC, the 6700/6500s will display a low voltage error which is a correct operating state because the power supply's voltage is decaying after it is powered off.

Tim, the message does not show when powering down the power supply any more.

Looks like there was a software change that is preventing that message from occurring when the power supply is shut down.  I just tested it and I am no longer seeing the message.
