Search tip.

If you have problem to find a manual, schematic or other file for a specific model, e.g. TM-2550 when you search with the keyword "TM-2550" or "TM2550" and not find any thing, it can occur that the model exist in the archive.
Some times a file can cover more models, and when this happened, it is typical named "TM-2530_2550_2570". So if you not find any thing when you search for "TM-2550" or "TM2550", then try to search for "2550" (search after the model number), this will maybe help you find the model you are looking for.
