I don't have enough context to understand what "vrtm-089" refers to. This could be:

1. A model number or product code

2. A code used in a specific system or database

3. Part of a file name or document identifier

4. An internal reference for an organization

Without more information about the context in which you're using this term, I can't provide a more specific or accurate response. If you have any additional details about where you encountered this code or what it might relate to, please share them and I'll do my best to assist you further.
