The DF02 (300 Baud) and DF03 (300/1200 Baud) modems appear to be singularly lacking in online documentation. In the case of the DF03 those would be:

EK-ODF03-IP - DF03 Illustrated Parts Breakdown
EK-ODF03-PS - DF03 Modem Pocket Service Guide
EK-ODF03-UG - DF03 Modem Users Guide

Similarly for the DF02. (Note that the actual designations may use a zero rather than a capital letter O in the 4th position; references are inconsistent.)

Does anyone have access to these documents? The only, and only slightly, useful technical documentation I've found are within the KC780 documentation (EK-KC780-TM-007_Jul84.pdf), which illustrates the required settings of the two pairs of DIP switches (or jumpers) on each of the two DF02/03 internal modules but doesn't define any of those settings. The functionality of the front panel push-button switches is not described either.

I've also got a DF03 that I'm looking for the documentation for... sadly, one of the fuses keeps blowing when put into self-test mode.
