Triomin Triton - Timekeeper

Hello all,

First time poster.

I live in Denmark and unfortunately my German is not very good. But I manage reading with help from Google Translate
I hope its ok that I post in English. I guess most of you may be better at understanding this instead of a Google translation. Otherwise, please let me know and I'll do my best to translate my questions to German.

I recently acquired a Triomint Trioton with a dead Timekeeper battery. I realize that I need to replace the battery and initialize the NVRAM in the Timekeeper.

Question:

1) Is the ST25 Service Keyboard sufficient for initializing the NVRAM, or do I need to program the [definition=9]TK[/definition] NVRAM with a known good image?
2) The manuals and list of service codes on the inside of the control box is missing. I managed to find a photo of the service codes, for a Triton, from this forum. So this is great. However, I was hoping to find some more documentation on this machine. I appreciate if anybody has any additional documents they are willing to share.

Thank you.
