Caution To prevent malfunction with other systems when receiving data in the NEC transmission
format, not only fully decode (make sure to check Data Code as well) the total 32 bits of the
16-bit custom codes (Custom Code, Custom Code’) and the 16-bit data codes (Data Code,
Data Code) but also check to make sure that no signals are present.
