RF exposure considerations
This module complies with FCC/IC RF radiation exposure limits set forth for an
uncontrolled environment. The module is limited to installation in mobile or
fixed applications. At least 20 Cm of separation distance between the
transmitting antenna and the user’s body must be maintained at all times.
The host manual shall include the RF exposure statements.
If the module is installed in a portable host, a separate SAR evaluation is
required to confirm compliance with relevant FCC portable RF exposure rules.
Antennas
The antenna is permanently attached to the module.
Antenna type: PCB pattern antenna
Label and compliance information
The module is labeled with its own FCC/IC. If the FCC ID/IC is not visible
when the module is installed inside another device, then the outside of the
device into which the module is installed must also display a label referring
to the enclosed module. In that case, the final end product must be labeled in
a visible area with the following:
“Contains FCC ID: CCECRM-1356BM ”, “Contains IC: 22254-CRM1356BM” The host
manual shall include the following regulatory statement:
This device complies with Part 15 of the FCC Rules. Operation is subject to
the following two conditions:
(1) This device may not cause harmful interference, and (2) this device must
accept any interference received, including interference that may cause
undesired operation.
Any changes or modifications not expressly approved by the party responsible
for compliance could void the user’s authority to operate this equipment.
The antenna(s) must be installed such that a minimum separation distance of at
least 20 cm is maintained between the radiator (antenna) and all persons at
all times.
Information on test modes and additional testing requirements
This module is tested in a standalone. Co-location of this module with other transmitters that operate simultaneously is required to be evaluated using the FCC multi-transmitter procedures.
Additional testing, Part 15 Subpart B disclaimer
The modular transmitter is only FCC authorized for the specific rule parts (i.e., FCC transmitter rules) listed on the grant, and the host product manufacturer is responsible for compliance to any other FCC rules that apply to the host not covered by the modular transmitter grant of certification. The host product may need to be evaluated against the FCC Part 15B criteria for unintentional radiators in order to be properly authorized for operation as a Part 15 digital device.
