Panasonic TOUGHBOOK Operating Instructions
Which manual do I choose?
Every TOUGHBOOK computer model is produced in different marks. To figure out what model and mark (MK) you have, look for your model number sticker. The first four characters are your model. The fifth character defines the MK. Use the lists below for reference.
For example: CF-195D-03LM is a CF-19 MK7. CF-3130451KM is a CF-31 MK5.
