Grundig 70-720/8 text

[GGV]

Hello from Australia to everyone.

I am new on this forum.
The Satellite TV and computers are my time spending.


Could some one help me with Grundig 70-720/8 text TV.
It is locked and I don't know the code.
The user manual or only the unlocking cod will be good.

Thahks
