Blaupankt 520 Car Stereo, for 2000 Holden Astra

I recently changed had to change the battery in my Astra as well and I guessed the security code 1111 and it goes into "TESTMODE" and everything works for a few minutes and then switches off again.
It's a Blaupunkt 520:
Holden Part no 29057957
Bosch Part no 8 622 401 324
How do I get it out of TESTMODE?

Nokia Phones sECURITY cODE !!!!

You are saying that you bought your cellphone from a resale shop, well according to me if your cellphone is a used one, the first owner of the cellphone must know the password. your should contact the dealer from whom you buyed your cellphone for the security code.
TRY THESE CODES ON YOUR CELLPHONE (these are default codes for the nokis phones)-

if above codes does not apply, then just try them once again with five digits.
(example- 1111,{five digit- 11111})
