undeliverable

I have been given a Mitel 5220 to join our existing Mitel IP network but the display is blank when I power it up.
I have tried all sorts of key combinations (superkey, up+down, *,#) when booting but it won't display anything.
I wonder if it has been SIP enabled previously which is why it won't work. Can it be reverted back again ?
Any ideas would be appreciated
Thanks
