nx210

I'm considering buying an NX210 that has been retired from a railroad, are these usually password protected? If so, is there any way to bypass the password? Also, do these radios use special firmware like some Icoms?

Does anyone here have any experience on how Kenwood's deal with the OST option for the NexEdge portable's? I am curious if the RX tone on channel stays the same (what is programmed into the firmware for that channel) when OST is on and using different TX pl tones. Hope this makes sense.... Thanks!
