Hello every one,
sorry if put it on the wrong thread..
Recently i bought trimble sitenet900 from ebay USA. its for my customer anyway. And while they want to use it, they said the "frequency or radio" didnt "match". so the device cant communicated each other.

i need to ask about how to unlock/change this trimble sitenet900 frequency.
If anybody here can do it, how much the fee for unlock it...

Really appreciate your help..
