3.3
The MRF24J40MC module conforms to the emission
standards summarized in
can be applied toward product certification and
Declaration of Conformity (DoC).
The European Standards do not provide a modular
approval similar to the USA (FCC) and Canada (IC).
However, the completed compliance testing can be
used as part of the customer’s application for product
compliance approvals. The module test report data can
be used as part of the customer’s product test plan and
can significantly lower customer’s compliance burden.
Depending on the end application, additional testing
may be required. The integrator is responsible for test-
ing the end product for any additional compliance
requirements that become necessary with this module
installed (for example, digital device emission, PC
peripheral requirements and so on) in the specific
country where end device is marketed).
3.3.1
To meet ETSI requirements, the following settings must
be observed by the integrator:
• The MRF24J40MC transmit power setting shall
Only channels 11 through 25 may be selected
(RFCON0 0x200).

Note:
not exceed 18.5 dBm peak (RFCON3 0x203<7:3>
= 00101) which for ETSI 300 328 requirements
equates to 9.8 dBm average (20 percent duty
cycle). When the MRF24J40MC module is
connected to a 2 dBi antenna, the EIRP is less
than 20 dBm. Refer to

(2006-10), Maximum e.i.r.p. spectral density limit,
Section 4.3.2.2, “For wideband modulations other then
FHSS (DSSS, OFDM, etc.), the maximum e.i.r.p.
spectral density is limited to 10 mW per MHz.”
