Calibrating of BH modules

Thas anybody know something about this.
I saw in CanopyRel4.2.3NotesIss1 manual description how to do this.
I try but always I am receiving for submited mac address * which means that is something wrong with mac address.

Than I visit http://moduleIP/mac.html and I found some values and I try to use them for calibration. After that BH link is working but I am receiving some strange RSSI value (-85dBm).

How to fix this?
