It does not necessarily need to be the correct firmware. Even with the incorrect firmware loaded there would be no problems using the system if the frequency selected puts your system within our ISM band. The class licence states 915-928MHz for the ISM band. Any value between 916MHz and 927MHz (center frequency) will keep you within the LIPD class licence. These channel frequencies are 1MHz inside the band limits to ensure all emissions are kept within the band.
I have one of the earlier units that were not user programmable for frequency. I deliberately specified it to be 923MHz to make sure it was legal.
True but you don't want to have to reprogram in the field because someone's on your frequency and have to try and figure out what the legal frequency is. Only reason to have another firmware is if your about to launch overseas.
