My company has an opportunity to pick up some of these units on service.

I have heard rumors that these are password controlled and that the password changes and also that you need to actually log-in to the units every so often with a service tool.

Was just looking to see what information this group has about these units and if it is very difficult to maintain/service these units. Also any documentation would be appreciated.

They are not difficult to work on or maintain, like any other just a learning curve. Have the building owner get a BOT(Building Only Tool) from fuji and there are no passwords
