Even if it did, it would just mean that it would use whatever ICOM decided was the default for the band.
If you are wanting to transmit on a system, then you need to ask the system engineer what the correct setting is.
If you are just receiving, the rule of thumb is that if the transmission is consistetly louder than other channels that you know are programmed correctly, then it is probably programmed as NFM when it should be FM. Conversely, if the channel is quieter than other channels, you've probably programmed a channel as FM when it should be NFM.
What screws up the rule of thumb is some agencies use shoulder mics that the operator might "talk past" resulting in low audio even if the modulation is correct. Similarly, seems that somem agencies have a majority of users who close-talk or yell into the mic...
