11.4 Requirements 1 -400 MHz: RI 112
The device shall operate as specified in Table 11-1 when exposed to the RF current levels and modulation listed and
illustrated in Figure 11-1. The currents are produced using the BCI test method.
RI 112 can not be used for component category AW (no wire harness). Alternative methods may be used (e.g. TEM cell), but
only with prior authorization by the FMC EMC department. The test method used, including test setup detail shall be
documented in the EMC test plan.
