Service Mode Telefunken TTV-29SX

Question

Hi there!
If you would be so kind as to provide me with the service mode sequence on a Telefunken TTV-29SX or perhaps a link to such info. I have browsed the web for any support but to no avail. Our support on the TTV Range is very limited. Your help would be greatly appreciated.

Kind Regards
