The following table provides the correlation between the numerical setting and the physical value for the EU
module (C1616, hardware Rev A 2.6HR1) and the US module (C1184, hardware Rev E).
C1616 – EU Module (Rev A 2.6HR1) C1183 – US Module (Rev E)

Table 8 – Power level to attenuation mapping tables
As visible from the table and charts above there are big differences in the range of adjustable power for the
EU/ETSI and US/FCC modules. So a power level setting (attenuation value) for the EU module can not be simply
transferred to the US module.
