First, change the Norstar system date to 11-21-00

2) FTR 9** (into RAD)
3) Press Left softkey 9 times
4) Press Center softkey 3 times
5) Press Right softkey 7 times
6) Press Hold
7) Press 2

  Now wait a few seconds & the Modem will reset.
You will be asked for a new passcode & this will involve
using just digits (0 to 9)!

Note!

Do not do 8) below

8) Press 1

Once done with the RAD be sure to reset the date.

That should be it. I've only used this one time 
(but did it twice to verify that it works).
