1. use your learning remote: learn the "toggle power" key from your Hitachi remote to your learning remote using the learning remote's learn feature.
2. use your jp1 cable: upload the eeprom memory from your learning remote to IR.exe (available at the yahoo jp1 files section).
3. use IR.exe: click the learn tab in IR.exe and you will see the decode of your "power toggle" signal. You will be told the protocol (such as NEC1, Panasonic, etc), the device and subdevice number that make it unique and set it apart from your other similarly branded devices, and most importantly, IR.exe will list THE OBC (EFC).
4. use the OBC: The OBCs (original button codes) are almost always grouped together by function. If your toggle power OBC is 72, your discrete power toggles are going to be 73 and 74, or 71 and 73, or 70 and 71, or something similar, if they exist.
5. convert to EFC: use KM to create a device upgrade for your device. On the function sheet you will be entering things like "power" and "72" in the columns labeled "function" and "obc". In the column next to the OBC column is the EFC column. Use the numbers here to test unknown EFCs on your device to see if they work (if you want to test EFC 039, point your remote at your device and press set-0-3-9 on your UEI remote). There may be better ways to convert OBCs to EFCs but I am new to all of this.
6. Finish your device upgrade in KM, paste it into IR, download it into your remote, crack open a cold one, and brag to your friends.
