RM5800 User Manual
1. An external label must be provided on the outside of the final product enclosure specifying the
FCC identifier as described in 5.1.3 below.
2. The antenna must be electrically identical to the FCC-approved antenna specifications for the
RM5800 as described in 5.1.2 with the exception that the gain may be lower than specified in
Section 5.1.2.
3. The device integrating the RM5800 may not cause harmful interference, and must accept any
interference received, including interference that may cause undesired operation.
4. An unintentional radiator scan must be performed on each final device integrating the RM5800,
per FCC rules and regulations, CFR Title 47, Part 15, Subpart B. If the final device system (host
product and modular transmitter) exceeds the spurious emissions or output power limit, the
product must not be marketed in the United States.
5. Professional installation as per section 4.3 of the modular integration manual, available upon

5.1.1
FCC Antenna Selection
The antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20
cm from all persons and must not be collocated or operating in conjunction with any other antenna or
transmitter within a host device, except in accordance with FCC multi-transmitter product procedures.
Compliance to FCC rule 15.203 must be ensured in the final design of the product. Reference KDB
353028 for direct guidance on meeting this requirement. This can be done by either ensuring the
professional installation of the final product or designing it in such a way as to make the antenna
integral to the final product. Further, the RM5800 is only utilized by Emerson internal companies, and is
not available to the general public. The RM5800 is an industrial network communication module and
only works on Wireless Hart protocols and as such is part of an industrial process control system
professionally installed and maintained per Section 4.3 of the modular integration manual, available
upon request.
5.1.2
