T28P - Power LED won't turn off

[bcdaus]

I have 4 T28P phones I recently purchased. I pushed them all to Firmware 2.73.0.50 and started to configure them.

I can't seem to get the power LED to go off no matter what I select in the Features -> Power LED section.
I want the Power light to be off by default and only show on an incoming call.

No matter what I do I cannot make the light go off. I have deselected all the power LED options and I still get the Green LED showing.

any thoughts ? All the phones are configured through the web interface and I have tried Factory Resetting the phones, but no change.

Version Info
Firmware Version 2.73.0.50
Hardware Version 1.0.1.1

Thanks,
Bill.
