Panasonic Toughbook Serial Number Breakdown

These are custom made models so the model numbers cannot be looked up in panasonic. Anyway, here is a link to the option list for a cf-29 Imagebin - A place to slap up your images. I have circled the T, 3 and 4. Software spellkaster torrent. How does the T relate to the model number on the back of the tough-book and the number options in that row? For example I have a Cf.

As a new reseller, I am looking for explanation of what all the details after the cf-19 cf-30 and so on. I am passed a list with the details of what is included with the units for resale but do not have yet, a master list of abbreviation. Take for example the tough-book android tablet the FZ-A1BDAAVAM. I know it is a tablet based on the FZ-A1 description.

But what do all the lettering after the model discretion mean? Does Panasonic or another site have a master description of all the lettering?
