Poly Studio P009 Password reset

Hello, My org has a few of these Poly Studio P009's. And they all have different passwords. We are trying to reset them to get them all to the same password. On the one in my office I have reset it. The computer see's it now. The software update took HOURS. But every version of "default" password I have found has not worked. I have tried the following:
Poly12#$
Polycom12#$ (with C and c)
admin
Admin
ADMIN

Nothing is working. Anyone have any ideas?
