whats wrong with the user manual in the pictures above.
If you dont know the codes you will need to get an engineer to default and then reprogram the system.
Came a cross this and thought it was a good idea add yourself to the map. Members will then all be able to get an easy idea where you are.

The site does not give out engineering manuals unless you are in the trade and can prove it.
Apply for trade membership if you are trade and there is a manual in the engineering manuals section.
If you are only using it as a bells only system then you dont need to change it simply because it is old. Bentley are still making them and supporting them with spares and manuals etc.
